US Strikes on Iran: Latest Developments, Targets and Impact on Iran-US Relations

Strait of Hormuz Updates on September 21 show a sharp split between two accounts of the same waterway. Kpler data reported by Reuters shows a dozen commodity vessels crossed over the weekend, down from 35 the weekend before. Meanwhile, US Central Command (CENTCOM) says volumes over the past two weeks are the highest in six months. Oil, LNG, insurance and diplomacy all depend on which picture is closer to the truth. This article separates verified data from claims made by each side. What Is the Strait of Hormuz and Why Is It Important? The strait separates the Arabian Peninsula from Iran and connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. At its narrowest it is 21 nautical miles (39 km) wide. Iranian and Omani territorial waters overlap in the passage. Saudi Arabia, Iraq, Kuwait, Qatar, the UAE and Bahrain all sit behind it. In 2025, about 20 million barrels per day (mb/d) of crude and products moved through it, roughly 25% of seaborne oil trade, with about 80% headed for Asia. Before the war it also carried about a fifth of the world’s LNG. The sections below combine this background with the latest Strait of Hormuz Updates on shipping, diplomacy and oil supply. Latest Strait of Hormuz Updates Traffic. Before the war began on February 28, the strait handled about 125 large commercial vessels a day. Kpler counted just four trackable exits on Sunday, September 20. Producers keep exporting on tankers with transponders off, so tracked counts understate real flows. LNG. Bloomberg data shows at least two LNG carriers transited this week, while two others made ship-to-ship transfers outside the strait, offshore Oman. Attacks. Iran said it attacked a Togo-flagged oil tanker on Thursday night, September 17, and maritime incident monitors said another ship was struck on Wednesday. Diplomacy and prices. Brent traded around $101.71 on Monday, its lowest since September 10, as traders weighed hopes for UN-week diplomacy. President Trump said he would be open to meeting Iranian President Masoud Pezeshkian. Strait of Hormuz Updates: Iran’s Position Iran’s positions come from officials and state media, and are not independently verified. In August, Iran said it would not fully reopen the strait until the US meets conditions including war compensation, sanctions relief and a permanent end to the conflict. On September 19, Iran’s security chief Mohsen Rezaei said Tehran had conveyed its conditions to mediators. Iran’s own institutions are not fully aligned. Its Foreign Ministry said on August 5 that it was finalizing a shipping-route agreement with Oman. Iranian state media reported that parliament was reviewing a plan to ban vessels linked to the US, Israel and other “hostile countries” and to charge other ships fees of up to 7% of cargo value. The two tracks have not been reconciled. Iran and the US have also given opposing accounts of conditions on the water. In June, Iran’s foreign ministry said shipping was “operating normally,” while CENTCOM said Iran did not control the strait. Strait of Hormuz Updates: US Position and Maritime Operations A US official told NPR in August that no party controls the lanes and that temporary routes must carry no approvals, permissions or tolls. Secretary of State Marco Rubio said in June that the strait would be toll-free under any final agreement. On September 19, CENTCOM commander Adm. Brad Cooper said US forces had assisted more than 2,000 commercial transits with coordinated protection, and that all Iranian mines had been cleared from the primary transit lanes. He also said about one billion barrels of oil left the Gulf in recent months, while Iran exported “zero barrels” because of a US blockade. Trump has said the waterway’s condition is acceptable for now with US military escorts. These are US military claims, and Iran disputes the US account of control over the lanes. Strait of Hormuz Updates: Shipping and Tanker Traffic The numbers differ because sources measure different things. Lloyd’s List Intelligence counted 114 transits from August 17 to 23, a rise of more than 30% on the week before, and said figures could rise as “dark” transits are confirmed. Lloyd’s List’s editor said cargo now moves through a relay of shuttles, ship-to-ship transfers and a limited pool of willing vessels, which concentrates the risk. CENTCOM counts escorted transits, while Kpler counts trackable commodity vessels. Neither is a full census. Costs. S&P Global reported in July that war-risk insurance had risen from 1–3% of hull value to 7.5–10%. Other trade estimates are lower and vary by date and voyage. Reuters-sourced reporting says freight from the Gulf of Oman to China hit a record $11.50 a barrel after the Saudi pipeline attack. Strait of Hormuz Updates: Impact on Global Oil and Gas Supplies EIA figures show Hormuz oil flows fell from 21.6 mb/d in the fourth quarter of 2025 to 4.9 mb/d in the second quarter of 2026. JPMorgan analysts said total Middle East oil flows averaged 17.1 mb/d over the past 10 days, 6.1 mb/d below the 2025 average. Saudi crude exports slumped to 2.4 mb/d in August, the lowest since at least 2013, and recovered to over 4 mb/d in September. The IEA estimates 410 million barrels have been drawn from global stockpiles since the war began. LNG is tighter. Executives told The National that about 36 million tonnes of Qatari and Emirati supply has been missing this year compared with 2025. The market has absorbed about three-quarters of the early-March losses, mainly through US production and redirected cargoes. Strait of Hormuz Updates: Alternative Routes and Shipping Options Only Saudi Arabia and the UAE have crude pipelines that can bypass the strait, with an estimated 3.5 to 5.5 mb/d of capacity. Saudi Arabia’s East-West pipeline was expanded to 7 mb/d, but the Yanbu terminals on the Red Sea have nominal loading capacity of only about 4.5 mb/d. That route is now under pressure. Reuters attributes attacks on the pipeline to the Houthis, and Saudi Aramco has halted some Yanbu shipments. The Houthis have also declared a blockade at Bab el-Mandeb, and going around Africa adds 20 to 25 days. Qatar’s LNG has no overland export option. The IEA’s Rebecca Schulz said that even after new pipeline projects finish, more than 10 mb/d would still need to pass through the strait to restore Gulf exports. Strait of Hormuz Updates and Iran-US Relations The waterway is now bound up with almost every dispute in Iran-US relations: the US blockade of Iranian exports, sanctions, compensation demands and Iran’s claim to oversight of the strait. The June memorandum of understanding required Iran to reopen the strait and charge no fees during its 60-day negotiating period. That framework has since broken down. The legal question is contested too. Under UN maritime law, ships have a right of transit passage through international straits, and Article 26 bars charges for mere passage. Iran’s toll plan directly challenges that reading. Strait of Hormuz Updates: Recent Diplomatic Efforts No signed reopening agreement exists. What exists are proposals and stalled talks. Iran-Oman corridor (proposal): Iran said in August it was finalizing a route agreement with Oman. A Malaysian Reserve report on September 17 said the two were close to a deal, but no major outlet reported one concluded. Salalah meeting (postponed): Oman’s foreign minister announced on September 13 that the September 14 meeting between Gulf diplomats and Iran was indefinitely postponed “in the interests of consensus.” Saudi Arabia had submitted amendments over concerns that the language could create a new status quo. Bahrain had refused to attend, while the UAE was pursuing quiet diplomacy. China: Iranian sources say China asked Iran to help rein in the Houthis after a Saudi appeal. Strait of Hormuz Updates: What Happens Next? Few next steps are confirmed. UN General Assembly week is the main diplomatic window, and Trump has said he is open to meeting Pezeshkian. No meeting has been announced. The postponed Salalah meeting has no new date, and no change in shipping restrictions has been announced. Aramco plans to raise exports through Hormuz this month and next. Whether traffic recovers, or whether attacks on ships continue, remains uncertain. Check back for further Strait of Hormuz Updates as diplomatic and shipping developments unfold. Strait of Hormuz Updates Timeline February 28: war begins and commercial traffic collapses. Late March: Lloyd’s List reports an IRGC-linked vetting scheme for approved transits. Mid-June: MoU signed, and the US lifts its blockade on June 18 according to one tracker. Iran re-declares closure on June 20, which CENTCOM disputes. August 5–6: Iran announces the Oman route work, and parliament reviews toll and ban plans. August 17–23: Lloyd’s List counts 114 transits. September 11: The East-West pipeline shuts down. September 13–14: Salalah meeting postponed. September 16–17: two tankers reported struck. September 19: CENTCOM update. September 21: Brent around $101.71, with Kpler reporting a weekend drop to 12 vessels. Frequently Asked Questions About Strait of Hormuz Updates What is the current situation in the Strait of Hormuz? Traffic is far below prewar levels by tracker data, while CENTCOM says volumes are at a six-month high. Attacks on ships continue. Why is the strait important to global oil supplies? About 20 mb/d passed through it in 2025, around 25% of seaborne oil trade, and bypass options are limited. How do Strait of Hormuz Updates affect shipping costs? Higher insurance, record freight rates, ship-to-ship transfers and longer alternative routes. What is Iran’s position on the Strait of Hormuz? Iran says it will not fully reopen the strait until its conditions are met, and its parliament is weighing tolls. How are Iran-US tensions affecting the strait? Disputes over the blockade, tolls, compensation and control of the lanes keep traffic depressed. Are ships currently passing through the Strait of Hormuz? Yes, but in reduced numbers, and many transit with transponders off.

Iran nuclear inspections are the process by which the International Atomic Energy Agency (IAEA) verifies whether Iran’s nuclear program is being used for peaceful purposes. These inspections sit at the center of a decades-long verification effort and, in 2025 and 2026, have become one of the most contested issues in global nonproliferation policy. Disputes over inspector access have also become tightly linked to the broader Iran-US relations dynamic, shaping sanctions decisions, diplomatic talks and UN Security Council debates. Understanding how Iran nuclear inspections actually work is essential to following these debates. What Are Iran Nuclear Inspections? Nuclear inspections are on-site checks carried out by IAEA officials to confirm that a country’s declared nuclear material and facilities are being used only for peaceful purposes, not diverted toward weapons development. Inspectors visit facilities, review records, install monitoring equipment such as cameras and seals, and take measurements of nuclear material. This is a technical verification process, not a political or intelligence assessment. IAEA inspectors report only on what they can independently confirm through access, documentation and physical measurement — they do not make judgments about a country’s intentions. That distinction matters in Iran’s case, where IAEA findings, US and European government statements, and Iranian official positions have frequently diverged. What Does the IAEA Inspect in Iran? Iran nuclear inspections cover a wide range of technical checks. Under Iran’s Safeguards Agreement with the IAEA, inspectors are authorized to examine: Nuclear material — tracking quantities and locations of enriched uranium and other safeguarded material Uranium enrichment facilities, including centrifuge halls at sites such as Natanz and Fordow Nuclear research and fuel-cycle facilities, including conversion and fuel fabrication plants Nuclear material accounting — reconciling declared stockpiles against physical inventories Environmental sampling — swabs and samples used to detect undeclared nuclear activity Monitoring equipment — cameras and seals that provide continuity of knowledge between visits Facility design information and access rights, which determine how thoroughly a site can be checked Why Are Iran Nuclear Inspections Important? Inspections give the international community independent, technical confirmation that declared nuclear material isn’t being diverted for weapons purposes. This matters for several reasons: it underpins global nonproliferation commitments under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), it builds diplomatic trust that can support sanctions relief or negotiated agreements, and it allows early detection of activities that fall outside a country’s declared program. Importantly, verification findings are distinct from political accusations — an IAEA statement that it “cannot verify” something is not the same as a finding that weapons activity is occurring, though the two are often conflated in public debate. History of Iran Nuclear Inspections The history of Iran nuclear inspections dates back to the early 2000s, when previously undeclared enrichment-related activities at Natanz and a heavy-water facility at Arak were revealed, triggering years of IAEA investigations and UN Security Council sanctions. Iran signed but did not fully ratify the Additional Protocol, which allows broader inspector access, and cooperation fluctuated for over a decade. That changed with the 2015 nuclear deal, which introduced the most intensive monitoring regime the IAEA had ever applied to a single country. It unraveled after the US withdrawal in 2018, and Iran progressively reduced its cooperation and monitoring commitments in the years that followed. The most dramatic rupture came after Israeli and US military strikes on Iranian nuclear facilities in June 2025 — during a 12-day conflict — after which Iran suspended cooperation with the IAEA and passed legislation requiring its Supreme National Security Council to approve any future inspections. Iran Nuclear Inspections and the 2015 Nuclear Deal The Joint Comprehensive Plan of Action (JCPOA), reached in July 2015 between Iran, the P5+1 powers (the US, UK, France, Russia, China and Germany) and the EU, made IAEA verification central to sanctions relief. Iran agreed to limits on enrichment levels, centrifuge numbers and stockpiles, alongside expanded monitoring including additional cameras, more frequent inspections and provisional application of the Additional Protocol. In exchange, the US and international partners lifted a range of nuclear-related sanctions. After the US withdrew from the agreement in 2018 and reimposed sanctions, Iran began stepping back from its commitments starting in 2019, gradually increasing enrichment levels and restricting monitoring access, including disconnecting some IAEA cameras in 2021 and further curbing cooperation in subsequent years. Challenges Facing Iran Nuclear Inspections Verification in Iran has faced sustained and escalating obstacles. Iran has stated that its cooperation has been constrained by threats to its nuclear facilities and personnel, arguing that normal safeguards implementation is legally difficult under current security conditions. The IAEA, for its part, reported that as of early 2026, Iran had allowed access to each of its unaffected nuclear facilities at least once since the June 2025 strikes, but had not provided declarations, reports or access relating to facilities that were damaged in the attacks. By mid-2026, the Agency’s quarterly report stated it remained largely unable to verify Iran’s implementation of its Safeguards Agreement or its JCPOA-related commitments, and said it had lost continuity of knowledge across all of Iran’s declared nuclear facilities, leaving it unable to account for the size or location of Iran’s enriched uranium stockpile. These gaps illustrate how fragile Iran nuclear inspections have become since 2025. Latest Iran Nuclear Inspections Developments Cooperation has moved through several distinct phases since mid-2025. In September 2025, Iran and the IAEA reached what became known as the Cairo Agreement, brokered with Egyptian mediation, establishing procedures for inspections and safeguards implementation across Iran’s declared facilities. Iran terminated that agreement on November 20, 2025. In January 2026, the IAEA warned Iran in writing that without further cooperation, it could not conclude that no declared nuclear material had been diverted from peaceful use. A February 2026 report said the Agency believed most of Iran’s stockpile of highly enriched uranium was stored at an underground tunnel complex at Isfahan, and urged Tehran to allow access there. Limited inspections did continue in early 2026, including at the Laboratory for Fuel Fabrication and a waste storage site at Karaj in February, and — reportedly at Russia’s urging — at the Bushehr power plant in June 2026. Diplomatic pressure escalated through 2026’s Board of Governors sessions. In June 2026, the Board adopted a resolution calling on Iran to disclose stockpile information and grant inspectors full access. Tensions peaked in September 2026, when the United States, joined by France, Germany and the UK (the “E3”), introduced a resolution at a special Board session citing Iran’s continued non-compliance and calling for the matter to be referred to the UN Security Council and General Assembly. The resolution passed on September 9, 2026, with Russia, China and Niger voting against it. Iran’s government dismissed the move as politically motivated and said it would have no practical effect. Separately, the E3’s 2025 invocation of the JCPOA “snapback” mechanism to reimpose UN sanctions remains disputed — Russia and China argue the underlying UN resolution expired in October 2025 before snapback took effect, while most other Council members treat the sanctions as reinstated, leaving unresolved questions about the sanctions committee’s mandate. Iran’s Position on Nuclear Inspections Iranian officials maintain that the country’s nuclear program is peaceful and that its safeguards obligations remain intact in principle, but that cooperation must reflect the security realities created by the 2025 military strikes and threats against nuclear personnel. Iran’s foreign ministry has said that eliminating these threats would create the conditions for renewed cooperation with the Agency, and Iranian diplomats have repeatedly characterized recent Board resolutions and Security Council actions as politically driven rather than technically justified. Iranian officials frame their approach to Iran nuclear inspections as conditional on security guarantees, not a rejection of verification in principle. US and International Concerns About Iran’s Nuclear Program The United States and European governments have expressed concern over Iran’s uranium stockpile, enrichment levels reported near weapons-grade purity, and the IAEA’s inability to verify material following the 2025 strikes. These are largely government and diplomatic positions rather than confirmed IAEA findings; the Agency itself has been careful to frame its statements around what it cannot verify due to lack of access, rather than asserting weapons activity is underway. Independent nonproliferation analysts have separately noted unresolved questions about the recovery status of equipment and enriched uranium from the damaged sites. Much of the international debate over Iran nuclear inspections centers on these unresolved technical gaps rather than confirmed conclusions. How Iran Nuclear Inspections Affect Iran-US Relations Verification access is now one of the central pressure points in Iran-US relations. US sanctions policy, snapback disputes at the UN, and any future negotiations over Iran’s nuclear program are all shaped by whether and how IAEA inspectors can confirm the status of Iran’s declared and previously undeclared material. Until inspection access is restored to pre-2025 levels, both diplomatic trust-building and sanctions-relief negotiations remain constrained. Iran Nuclear Inspections Timeline Early 2000s: Undeclared enrichment activity revealed; IAEA investigations begin July 2015: JCPOA signed, introducing expanded monitoring May 2018: US withdraws from the JCPOA 2019–2021: Iran reduces nuclear commitments and monitoring cooperation June 2025: US-Israeli strikes on Iranian nuclear sites; Iran suspends IAEA cooperation September 2025: Cairo Agreement reached with Egyptian mediation November 2025: Iran terminates the Cairo Agreement; Board reinstates reporting mandate February 2026: IAEA reports Isfahan tunnel complex likely holds most HEU stockpile June 2026: Board resolution demands stockpile disclosure and access September 2026: Board refers Iran’s case to the UN Security Council and General Assembly Frequently Asked Questions What are Iran nuclear inspections? They are on-site checks by IAEA inspectors verifying that Iran’s declared nuclear material and facilities are used only for peaceful purposes. Who conducts nuclear inspections in Iran? The International Atomic Energy Agency, a UN-affiliated technical body, conducts inspections under Iran’s Safeguards Agreement. What does the IAEA look for during inspections? Inspectors verify nuclear material quantities, check enrichment and fuel-cycle facilities, review records, and use monitoring equipment and environmental sampling. Why are Iran nuclear inspections important? They provide independent confirmation for nonproliferation purposes and underpin diplomatic trust in any nuclear-related agreement. How are Iran nuclear inspections connected to the JCPOA? The 2015 deal built its sanctions relief around an expanded IAEA verification regime; cooperation has narrowed sharply since the US withdrew in 2018. What is the current status of Iran nuclear inspections? As of September 2026, the IAEA says it cannot fully verify Iran’s safeguards compliance or account for its enriched uranium stockpile, and the Board of Governors has referred Iran’s case to the UN Security Council.

The United States and Denmark have signed off on a security deal for Greenland, ending a months-long standoff that began when President Donald Trump threatened to seize the Arctic territory by force. Trump announced on Truth Social that Denmark would grant the US “permanent control over security, and all other needs” in the semi-autonomous Danish territory, with the agreement expected to be formally signed next week at the UN General Assembly. NATO welcomed the arrangement, saying it would help stabilize the region. Denmark’s Prime Minister Mette Frederiksen and Greenland’s Prime Minister Jens-Frederik Nielsen issued a joint statement calling the deal a step toward “strengthened security,” though neither leader released details of what it actually contains. What the deal reportedly includes No official text has been published. The BBC has contacted the Danish Embassy in the US and the White House for comment. In the meantime, an unnamed US State Department official described the broad strokes of the agreement without providing a copy. According to that official, the deal would not expire even if Greenland becomes an independent country at some point in the future. It gives the US unilateral authority to build additional military structures on the island, with no approval required from either Greenland or Denmark. The official said this includes “permanent access, basing and overflights rights.” The agreement also bars non-NATO countries from building bases in Greenland and blocks what the official called “adversaries” — specifically naming Russia and China — from making investments in sectors considered sensitive to US security. Under the current setup, the official said, those countries have been able to invest in sensitive parts of Greenland’s economy without any investment screening. It remains unclear exactly how this arrangement differs from a 1951 agreement between the US and Denmark, which already allows the US to station an unlimited number of troops in Greenland. The US currently keeps more than 100 military personnel at Pituffik Space Base, on the territory’s northwestern tip. Trump claims a win, but no territory changes hands Trump wrote that the deal came at “no cost to the United States” and would let Washington “do what is necessary” to “secure and defend the security of Greenland.” He said it also bars any US adversary from maintaining a military presence in Greenland or making “sensitive investments in Greenland, without our express written approval.” For months, Trump pushed to buy or annex Greenland outright, arguing the island was vulnerable to Russia and China and pointing to its strategic location and mineral deposits. Those demands triggered backlash from Greenlanders, Danes, and other NATO allies, and US Vice-President JD Vance’s visit to Pituffik Space Base earlier this year was widely seen in Copenhagen and Nuuk as a provocation. Despite the rhetoric, no territory has changed hands, and Frederiksen’s statement specifically noted the deal recognizes “the sovereignty and territorial integrity of the Kingdom and the right of the Greenlandic people to self-determination.” Danish media have framed this as a win for Copenhagen’s diplomacy. The newspaper Berlingske ran the headline “Don’t tell Trump that it’s the Kingdom of Denmark that has won,” while a Politiken correspondent in the US wrote that “Trump didn’t get Greenland, but he was allowed to take a victory lap on social media.” Reactions from Nuuk, Paris, and beyond Nielsen, Greenland’s prime minister, called it “gratifying that we are about to enter into an agreement that ensures and strengthens the security of Greenland, the Kingdom of Denmark, the United States and the Western alliance.” He added: “The agreement recognises Greenland’s interests and our place in international co-operation. It is for the benefit of us all.” French President Emmanuel Macron offered a more cautious take, telling the AFP news agency the deal helped “reaffirm Danish sovereignty” over the island. “I simply note that Danish sovereignty is respected, that international law is respected, and that this is what we were asking for. So it’s a good thing,” he said. Not everyone in Greenland is convinced yet. MP Naaja Nathanielsen called it “news we have all been hoping for” in a social media post, but added: “It is absolutely crucial that any agreement preserves our right to self-determination.” Former Greenlandic politician Aaja Chemnitz was more guarded, saying she looked forward to the deal being finalized but “until then, I’m sceptical.” She added: “I don’t have much confidence in Trump.” The agreement still needs to clear what Frederiksen and Nielsen’s joint statement described as “the necessary parliamentary procedures to enter into force” once it’s signed. Why Greenland matters to Washington Greenland sits between North America and the Arctic, making it valuable for early-warning missile detection systems and for tracking vessel movement in the region. Trump has said the island is essential to his planned Golden Dome missile defense system, which is meant to protect the US from attacks by Russia and China, and has suggested European allies could take part in building it. The territory also holds large, largely untapped reserves of rare earth minerals used in mobile phones, electric vehicles, and other technology. That resource wealth, combined with its geographic position, has kept Greenland on Washington’s radar well before Trump’s latest push. With the text of the agreement still unreleased, much of what happens next depends on details that haven’t been made public. Whether the deal genuinely settles the dispute or simply postpones the next round of pressure from Washington will likely become clearer once Denmark, Greenland, and the US put pen to paper next week.

The UN human rights office published a report on Friday documenting 1,004 verified cases of conflict-related sexual violence in Ukraine between February 2022 and July 2026, attributing 89 percent of them to Russian forces and 11 percent to Ukrainian ones. Investigators recorded gang rape, genital mutilation and the use of electric shocks on men’s genitals in Russian detention, and threats of sexual violence and beatings to the genitals in facilities run by Ukraine. The Office of the UN High Commissioner for Human Rights built the figures from interviews with survivors of abuse committed by both sides. The count covers the period from Russia’s full-scale invasion through July of this year. Most of the survivors are men The most striking finding in the report cuts against what most people assume about wartime sexual violence. In detention settings, the majority of victims were men, particularly prisoners of war and civilian detainees. Women and children were also affected, mostly in Russian-occupied areas rather than in captivity. Danielle Bell, who heads the UN Human Rights Monitoring Mission in Ukraine, said the public understanding of the problem does not match what her team found. She noted that in the Ukraine context, most survivors are men, and that men and women need different approaches to recovery. That distinction matters for anyone designing support services. Medical care, legal aid and psychological treatment built around female survivors will miss the group that makes up the bulk of documented cases here. What happened in Russian custody Russian authorities inflicted sexual violence on Ukrainian prisoners of war and detained civilians at every stage of captivity, according to the report. That covers the moment of capture, transfer between facilities, interrogation and the length of detention itself. The pattern appeared both in occupied parts of Ukraine and inside Russia. Documented violations include rape, gang rape and genital mutilation. Interrogators also applied electric shocks to men’s genitals using a Soviet-era military field telephone that detainees call a “tapik,” a device that generates current when its handle is cranked. Investigators concluded that Russia took no steps to prevent these acts, investigate them or prosecute the personnel responsible. The Russian government also ignored requests for information from OHCHR. Its permanent mission in Geneva declined to comment on the findings. Ukraine’s record Nearly half of the violations attributed to Ukrainian authorities involved threats of sexual violence and beatings to the genitals, directed at Russian and third-country prisoners of war and detainees. OHCHR documented no cases of rape of Russian prisoners by Ukrainian forces. The geography of those reports is worth noting. Prisoners described abuse in 10 official detention facilities and 55 unofficial or transit locations. The unofficial sites outnumber the formal ones by more than five to one, which points to a monitoring gap in exactly the places where oversight is weakest. OHCHR credited the Ukrainian government with taking some preventive measures and with cooperating with its requests for information. Accountability, the office said, remains limited. Cooperation is not the same as prosecution. Ukraine’s foreign ministry welcomed the report in a statement, saying it showed the scale of violations committed by Russia and the steps Kyiv has taken to prevent such violence and compensate victims. The statement said nothing directly about the incidents involving Ukrainian forces. The numbers are almost certainly too low The report warns against reading 1,004 as a total. Conflict-related sexual violence goes badly under-reported in every war, and the conditions in this one make the gap wider than usual. Russia has refused to give OHCHR access to occupied Ukrainian territory, to prisoners of war and to civilian detainees. Investigators could not enter the facilities where they believe most of the abuse occurred. Everything documented in Russian custody comes from people who got out and agreed to describe what happened to them. Survivors also face reasons not to speak. Shame, fear of reprisal against family still in occupied areas, and the near-total absence of services for male survivors all suppress reporting. Some detainees remain in captivity and cannot report anything at all. Volker Turk, the UN High Commissioner for Human Rights, said he is deeply alarmed by how common these acts appear in the documented record. He added that he fears they are almost certainly continuing while the fighting goes on. What happens next Three things will determine whether this report changes anything. Access is the first. OHCHR cannot verify what it cannot see, and Russia has blocked entry to occupied territory and detention sites since 2022. Without that access, every future report will carry the same caveat and the same undercount. Any prisoner exchange or ceasefire arrangement that includes independent monitoring of detention facilities would change the evidentiary picture immediately. Prosecution is the second. The International Criminal Court and Ukraine’s own prosecutor general both have open investigations into conflict-related sexual violence. Cases involving Russian personnel will mostly proceed in absentia, since Moscow will not surrender suspects. Cases involving Ukrainian personnel are a test Kyiv now faces in public: it welcomed the report while declining to address its own forces’ conduct, and OHCHR has already said accountability efforts there fall short. Care for survivors is the third and the most immediate. Ukraine’s health system and the aid organizations working alongside it have to reach a survivor population that is mostly male, mostly released prisoners of war, and largely invisible to programs designed for women. Bell’s point about different approaches was not a rhetorical aside. It describes a service gap that exists right now, for people who came home from captivity and have nowhere to go with what happened to them.

For anyone following Iran US Ceasefire Updates, the situation is unsettled. The 14-point memorandum of understanding (MoU) signed on June 17 formalized a ceasefire and opened a 60-day window to negotiate a permanent deal. That framework has since broken down, and no replacement has been announced. Peace talks remain stalled, the Strait of Hormuz remains contested, and diplomats are working around the UN General Assembly. This article separates what is confirmed from what each side claims. For broader context, see our Iran-US relations overview. What Is the Current Status of the Iran US Ceasefire? No formal ceasefire is operating as the June MoU intended. On July 8, President Trump said that “as far as I’m concerned, it’s over,” while adding that he would allow peace talks to continue. Iran has not declared the arrangement dead. On September 1, President Masoud Pezeshkian said Iran would “immediately reciprocate” if the US returned to its MoU commitments. Fighting has been uneven since July. TIME reported that active hostilities resumed in early September, with tankers near Hormuz coming under fire. The independent GlobalSecurity tracker, an aggregator rather than an official source, reports no new Iranian attack on any host state for nine consecutive days as of September 18. That is an informal lull, not an announced truce. On September 17, Trump told Axios he is approaching a critical juncture over whether to restart attacks. How the Iran US Ceasefire Agreement Developed The framework behind these Iran US Ceasefire Updates has three stages. April. A Pakistan-brokered two-week ceasefire was announced on April 7, hours before a Trump deadline over Iranian infrastructure. No jointly agreed text was released, and the two sides’ differing public statements foreshadowed later disputes. Vice President JD Vance then traveled to Pakistan for talks, and the ceasefire was extended indefinitely in late April. June. The MoU set a 60-day negotiating period. The US agreed to end its naval blockade, refrain from new sanctions and work on an economic reconstruction package. Iran agreed to clear Hormuz of mines and allow trade. The ambiguity. The text asked Iran for “best efforts” on safe passage without fees for the 60 days only, which left open the possibility of later service fees. The two sides read that language differently. Major Developments Since the Ceasefire June 25: Iran launched a drone strike on a ship in Hormuz, which the US interpreted as a violation. The exchange of fire ended shortly afterward. July 7–8: Iran struck three vessels, and the US rescinded Iran’s license to sell oil internationally. Trump then declared the ceasefire over, and the US hit 90 targets according to CENTCOM. July 28: Mediators led by Qatar and Pakistan reported progress after both sides paused attacks. August 8–10: Iran set six conditions for reopening Hormuz, and Trump responded by demanding compensation from Tehran (details below). August 30–September 2: The US struck Larak Island, and the IRGC retaliated against US bases in Jordan. On September 2 the IRGC announced further operations against US positions in Jordan, Bahrain and Iraq. September 8–9: CBS News, citing people with direct knowledge, reported that Iranian missiles damaged US aircraft at Muwaffaq Salti Air Base in Jordan. Iran US Ceasefire Updates: Violations and Disputes Both governments accuse the other of breaking the deal. TIME reported that the MoU collapsed when Washington and Tehran accused each other of violations and could not agree on next steps. The US points to Iranian attacks on commercial shipping. Iran and its officials argue the MoU allowed it to keep some authority over the strait. Iranian Parliament Speaker Mohammad Bagher Ghalibaf said Hormuz “will only open with Iranian arrangements.” Vance said US strikes were directly linked to Iranian actions in the strait. A separate dispute concerns nuclear inspections. GlobalSecurity’s daily war calendar records that Vance called an inspection agreement a major milestone while an Iranian spokesperson disputed that Iran had agreed to readmit IAEA inspectors. That claim is unverified here, so readers should treat it as contested. The Role of Diplomacy and Negotiations These Iran US Ceasefire Updates also cover the diplomatic track. Public signals from Washington have shifted. On August 27, Trump said the US did not want to speak to Iran. On September 14 he said the US was open to restarting negotiations, and on September 16 he said he had heard from Iran “directly” without giving detail. The last official high-level talks took place in Switzerland in June. Iran is also sending mixed signals. Pezeshkian and Foreign Minister Abbas Araghchi emphasize diplomacy, while hard-liners such as IRGC General Ahmad Vahidi favor confrontation. Mohsen Rezaei, secretary of the Supreme National Security Council, said on September 14 there would be “no talks until Iran’s conditions are met.” Those conditions were laid out on August 8. Iran’s Supreme National Security Council said Hormuz would stay closed until the US ends threats and attacks on Iran and its allies, lifts the naval blockade, pays war compensation, lifts sanctions and releases frozen assets. Trump answered on August 10 that he would require compensation from Iran. The US is also pursuing economic pressure. Treasury Secretary Scott Bessent said Washington intends to economically “asphyxiate” the regime. Why the Strait of Hormuz Matters to the Iran US Ceasefire No set of Iran US Ceasefire Updates is complete without Hormuz. Around a fifth of global oil production flowed through the strait before the war began on February 28. Kpler data shared with TIME showed five ships crossing on September 16, against about 138 in a typical prewar 24-hour period. Oil prices rose above $100 a barrel in the week of September 9, the first time since July. Iran’s stated position is that the waterway is now a bargaining tool. An IRGC spokesman said Tehran’s strategy is to maintain control of the strait until its conditions are accepted. Washington’s position is that the passage must stay open. Trump has repeatedly said the US has near-total control of the waterway, though traffic remains disrupted. The Red Sea adds pressure. Yemen’s Houthis captured Perim Island in the Bab el-Mandeb Strait last week, and experts told TIME this could give Tehran added leverage. Iran US Ceasefire Updates: International Mediation Efforts Pakistan: brokered the April ceasefire and hosted the first high-level talks. Qatar: a key mediator, whose prime minister visited Tehran on August 27. Oman: involved in talks with Iran on a temporary shipping corridor and mine clearance in the strait. Gulf states: postponed a planned meeting with Tehran on reopening Hormuz on September 14. China: privately asked Iran to help rein in the Houthis, according to Iranian sources cited by Reuters. United Nations: Russia and China vetoed a US resolution on September 17 that would have renewed the mandate of UN experts monitoring nuclear sanctions on Iran. Iran US Ceasefire Updates: What’s Blocking a Lasting Deal? Hormuz control: Iran seeks a continuing role and possible fees, while the US wants unrestricted passage. Sanctions and assets: Iran demands full relief and release of frozen funds, while the US is adding economic pressure. Blockade and forces: Iran wants the naval blockade lifted and US forces withdrawn. Nuclear program: inspection access and the future of Iran’s program remain contested. Compensation: Iran demands war reparations, and Trump has demanded compensation from Iran. Trust and sequencing: each side says the other must move first, and Iran’s leadership is publicly divided. What Happens Next in the Iran US Ceasefire Story? The next entry in these Iran US Ceasefire Updates will likely follow the UN General Assembly. Only a few steps are confirmed. Trump is expected to meet Gulf leaders on the sidelines of the UN General Assembly on Tuesday, September 22, to discuss next steps, according to Axios. The State Department has approved visas for Iran’s core UN delegation, including Pezeshkian and Araghchi. No direct US-Iran meeting has been announced. Whether talks resume, or whether the US restarts strikes, remains uncertain. Iran US Ceasefire Updates: Full Timeline Date Event February 28 US and Israeli strikes on Iran begin April 7 Two-week ceasefire announced Late April Ceasefire extended indefinitely June 17 14-point MoU signed June 25 First alleged violation July 8 Trump says the ceasefire is “over” July 28 Mediators report progress after a pause August 8 Iran issues six conditions Aug 30–Sept 2 US strike on Larak Island and IRGC retaliation September 8–9 Iranian strike on Jordan base reported September 17 Trump says he is weighing whether to restart attacks September 22 Trump expected to meet Gulf leaders at the UN FAQ: Iran US Ceasefire Updates What is the current status of the Iran US ceasefire? The June MoU framework has collapsed, and no new formal ceasefire has been announced. An informal lull in reported strikes has held since about September 9, according to one tracker. When did the Iran US ceasefire begin? The first ceasefire was announced on April 7, 2026, and the MoU followed on June 17. What were the main terms of the Iran US ceasefire? A 60-day negotiating window, an end to the US blockade, no new US sanctions, Iranian mine clearance, and trade through Hormuz. Why has the Iran US ceasefire faced difficulties? Disputed Hormuz language, attacks on shipping, US retaliation and mutual violation claims. Are Iran and the United States currently negotiating? Not formally. Trump says he is open to talks, Iran says none can happen until its conditions are met, and mediators are still working. Why is the Strait of Hormuz important to the Iran US ceasefire? It carries about a fifth of global oil, and control over it is Iran’s main leverage.

The Iran US nuclear talks have gone through one of the most turbulent stretches of any modern diplomatic process — swinging between cautious optimism, outright war, and a written agreement that collapsed within weeks of being signed. As of mid-September 2026, the ceasefire established by the Islamabad Memorandum has effectively broken down. After President Trump declared the agreement “over” in early July, fighting flared repeatedly through the summer, including a fresh round of US and Iranian strikes in the first two weeks of September. The IAEA’s Board of Governors has now adopted a resolution urging Iran to cooperate on nuclear inspections, and both sides continue trading strikes even as diplomats say a return to talks remains possible. Here’s how the talks got here, what was actually agreed to, and why the fighting resumed. How the Iran US Nuclear Talks Began The current round of diplomacy traces back to March 2025, when President Trump sent a letter to Iranian Supreme Leader Ali Khamenei proposing new negotiations, while warning of serious consequences if Iran refused. After initial hesitation, Iran agreed to indirect talks, and the first round was held in Muscat, Oman, in April 2025, led by US special envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi. Several more rounds followed in Rome and Muscat over the following weeks, with both sides describing the Iran US nuclear talks as constructive even as sharp disagreements persisted over Iran’s uranium enrichment rights, its stockpile of highly enriched uranium, and the scope of sanctions relief. Trump’s team pushed for a complete end to Iranian enrichment, while Tehran insisted enrichment was a non-negotiable right. A 60-day deadline set by Trump passed without an agreement, and on June 13, 2025, Israel launched large-scale strikes on Iranian military and nuclear targets, triggering what became known as the Twelve-Day War. The United States subsequently struck Iran’s Fordow, Natanz, and Isfahan nuclear facilities directly. Talks collapsed, and Iran suspended cooperation with the International Atomic Energy Agency (IAEA) shortly afterward. The Path Back to the Table — and a Second War Diplomacy resumed in early 2026 following mass protests inside Iran, even as the US continued building up its military presence across the Middle East. But the reprieve was short-lived. On February 28, 2026, the United States and Israel launched a fresh round of large-scale strikes on Iran, marking the start of what’s now referred to as the 2026 Iran war. The strikes included the assassination of Ali Khamenei himself, along with senior security official Ali Larijani, who had been closely involved in the negotiations. Months of fighting, competing ultimatums, and stalled talks followed. Trump alternated between demanding what he called Iran’s unconditional surrender and expressing optimism that a deal was close — CNN later counted at least 38 separate occasions between March and June 2026 where Trump claimed an agreement was imminent. A brief two-week ceasefire announced on April 7 quickly ran into complications when Israel struck Lebanon the same day, with Iranian officials warning the truce couldn’t hold unless it extended to Lebanon as well. The Islamabad Memorandum The breakthrough — such as it was — came on June 17, 2026, when Trump and Iranian President Masoud Pezeshkian remotely signed the Islamabad Memorandum, a framework agreement aimed at ending hostilities. Trump signed it during a dinner with French President Emmanuel Macron at the Palace of Versailles following the G7 summit, while Pezeshkian signed separately in Tehran. According to a summary from the UK House of Commons Library, the memorandum calls for a permanent halt to military operations on all fronts, including between Israel and Hezbollah in Lebanon, and states that Iran will not possess a nuclear weapon. It also outlines a roughly $300 billion reconstruction plan for Iran, a process for lifting sanctions, and a framework for IAEA inspection of Iran’s nuclear program and disposal of its enriched uranium stockpile — with the detailed terms of all three left to be worked out in follow-up talks during an initial 60-day window. The agreement was not universally welcomed. Israeli Prime Minister Benjamin Netanyahu reportedly told Trump that Israel did not consider itself bound by the memorandum’s Lebanon provisions and would keep its forces in place. Inside Iran, hardliners criticized the deal, even as Khamenei’s son Mojtaba Khamenei publicly endorsed it despite what he described as reservations. The Ceasefire Collapses The 60-day window that followed the memorandum’s signing proved short-lived. Late in June 2026, Trump accused Iran of violating the truce by launching drone attacks on shipping in the Strait of Hormuz, and US Central Command responded by striking Iranian missile and drone storage sites along with coastal radar stations. By early July, the situation deteriorated further. After Iran struck commercial vessels in the Strait of Hormuz to assert its claim over the waterway, Trump declared on July 8, 2026, that the Islamabad Memorandum was “over,” though he said negotiators could keep talking. Sustained fighting has continued on and off ever since, with US and Israeli strikes and Iranian retaliation across the Gulf region. Hostilities briefly quieted for roughly a month in August 2026, but renewed strikes broke that calm at the end of the month. On September 1, a US strike reportedly hit a home hosting a wedding in Iran, killing several people, and Iran responded with missile and drone attacks across the region. By September 9, Iran’s Revolutionary Guard had struck a US base in Jordan and US Central Command said it had destroyed several Iranian oil tankers, even as Trump suggested on social media that the war could wind down after November’s US midterm elections. The Core Unresolved Issue in Iran US Nuclear Talks: Inspections Nearly three months after the memorandum was signed, the disagreement that keeps resurfacing is over IAEA access to Iran’s nuclear sites. Director-General Rafael Grossi has said the memorandum explicitly commits Iran to having its nuclear activities supervised by the agency, and that inspections of the bombed enrichment facilities are going to happen, regardless of the timeline. Iranian officials have pushed back, arguing that under the memorandum’s terms, questions about inspecting war-damaged sites can only be resolved as part of a final, comprehensive agreement — not before one exists. In practice, that dispute has meant the IAEA has been unable to visit Iran’s Fordow, Natanz, or Isfahan facilities since the strikes, and has only maintained access to unaffected sites like the Bushehr power plant. On September 9, 2026, the situation escalated from words to formal action: the IAEA Board of Governors adopted a resolution urging Iran to cooperate with the agency, following a special session where Grossi briefed the board on the continued lack of access and on monitoring equipment that Tehran has reportedly disabled. Iran is believed to be sitting on enough highly enriched uranium — some estimates put it near 400 kilograms — to produce material for as many as ten nuclear weapons should it choose to pursue that path, though both Iran and the IAEA maintain that no enrichment to weapons-grade levels has taken place. Sanctions Relief and Reconstruction Money The second major sticking point is money. The memorandum ties sanctions relief and the proposed $300 billion reconstruction package to progress on the nuclear file, but the sequencing has never been fully settled: Iran wants tangible economic relief and restored banking access before making further nuclear concessions, while the US has generally wanted verified compliance first. Reports throughout the summer also suggested the US was weighing whether some of Iran’s frozen assets — estimated in different reports at between $24 billion and $25 billion — could be released or redirected toward reconstruction costs tied to war damage, adding another layer of complexity to the financial side of the deal. Other Sticking Points A handful of other issues continue to complicate the picture: Missile program: Iran has repeatedly said its ballistic missile capabilities are not on the table for negotiation, a position reaffirmed by President Pezeshkian, while US lawmakers and Gulf allies have pushed for missile limits to be included in any lasting deal. Lebanon and Hezbollah: Despite the memorandum’s language on ending hostilities on all fronts, Israel has maintained it isn’t bound by the Lebanon provisions, leaving that piece of the wider settlement effectively unresolved. Domestic politics in both countries: Polling has shown deep skepticism on both sides — a majority of Americans in some surveys expressed low confidence in any nuclear deal with Iran, while inside Iran, economic hardship tied to the conflict has fueled public frustration and calls for political change. What’s at Stake The stakes extend well beyond the two countries directly involved. IAEA officials have warned that an Iranian nuclear weapon could trigger wider proliferation across the Middle East, as other regional powers move to acquire similar capabilities in response. A verified, lasting agreement would also determine whether the Strait of Hormuz — a critical corridor for global oil shipping — remains fully open, and whether the broader web of conflicts touching Lebanon, the Gulf, and Iran’s regional proxies can be meaningfully de-escalated. Where the Iran US Nuclear Talks Stand Now As of mid-September 2026, the Islamabad Memorandum is no longer functioning as an active ceasefire, even though Iran has publicly called for a return to its terms. Fighting between the US, Israel, and Iran has continued intermittently for more than six months, spiking global oil prices and creating political pressure on the Trump administration ahead of the midterms. On the nuclear inspections front, the IAEA Board’s September 9 resolution marks a formal step up in pressure on Iran, though it stops short of resolving the underlying access dispute. Sanctions relief and the proposed reconstruction package remain tied up in the same sequencing dispute that has stalled progress since June, and the missile and Lebanon issues remain outside the framework entirely. Given how many previous breakthroughs in this process have unraveled, any further progress will likely continue to arrive in small, contested steps — if it arrives at all — rather than in a single clean resolution.

Few bilateral relationships have shifted as dramatically as the one between Iran and the United States. Iran US relations history helps explain why the two countries have spent more than four decades as adversaries after once being close allies. From early diplomatic ties in the 19th century to a CIA-backed coup, a revolution, a hostage crisis, and a fractured nuclear agreement, this timeline traces the key events that continue to shape Iran-US relations today. For a broader overview of the topic, see this guide to Iran-US relations. Iran US Relations History: The Early Years Formal diplomatic contact between the United States and Iran, then known internationally as Persia, dates back to the late 19th century. The two countries signed a Treaty of Amity in 1856, and the United States opened a legation in Tehran in 1883. For decades, the relationship was distant but generally cordial, since the US had no colonial history in the region, unlike Britain and Russia, which competed for influence over Persian oil, trade routes, and territory. In the early 20th century, American advisers occasionally assisted Iran with financial and administrative reforms. Iran’s official name changed from Persia to Iran in 1935. Relations remained modest until the mid-20th century, when oil, Cold War politics, and rising nationalism transformed the relationship into one of far greater strategic importance. The 1953 Iranian Coup and Its Impact One of the most consequential episodes in the history of US-Iran relations occurred in 1953. Prime Minister Mohammad Mossadegh, who had nationalized Iran’s British-controlled oil industry in 1951, became a target of British and American intelligence services. Britain, which had lost access to Iranian oil revenue, lobbied Washington to help remove him, framing the dispute partly in Cold War terms as a way to prevent Soviet influence in Iran. Declassified cables and reports on the operation are now available through the U.S. State Department’s Office of the Historian. In August 1953, a covert operation coordinated by the American CIA and British intelligence contributed to Mossadegh’s overthrow. Shah Mohammad Reza Pahlavi, who had briefly fled the country, returned and consolidated power with US and British support. The 1953 coup became a defining grievance for many Iranians. It is frequently cited as a key reason for the deep distrust of the United States that later fueled the 1979 revolution, and it remains a central reference point in Iran US relations history. US-Iran Relations Under the Shah Following the coup, the United States and Iran developed a close strategic partnership that lasted more than two decades. The Shah positioned Iran as a reliable Western ally in the Middle East during the Cold War, and Washington in turn supported his government politically, economically, and militarily. Key features of this period included: Military cooperation: Iran purchased large quantities of American weapons and received US military training and advisers. Economic ties: American companies invested in Iran’s oil sector and broader economy, and Iran used oil revenue to fund rapid modernization programs. Political support: US administrations largely overlooked human rights concerns tied to the Shah’s secret police, SAVAK, in exchange for Iran’s role as a regional counterweight to Soviet influence. This close alignment made Iran one of the closest US allies in the Middle East by the 1970s, but it also deepened resentment among Iranians who viewed the Shah’s government as beholden to Washington. The 1979 Iranian Revolution By the late 1970s, opposition to the Shah’s rule had grown across multiple segments of Iranian society, including religious leaders, students, and secular nationalists, who objected to political repression, economic inequality, and perceived foreign interference. Mass protests intensified through 1978, and the Shah left Iran in January 1979. Ayatollah Ruhollah Khomeini, a Shia religious leader who had spent years in exile, returned to Iran in February 1979 and became the leading figure of the revolution. An Islamic Republic was declared soon after, replacing the monarchy with a system based on religious governance. The revolution fundamentally altered Iran-US relations. The new Iranian leadership viewed the United States as having propped up the Shah and interfered in Iran’s internal affairs, particularly by referencing the events of 1953. Anti-American sentiment became a defining feature of the new government’s rhetoric and policy. The Iran Hostage Crisis Tensions escalated sharply in November 1979, when Iranian students supportive of the revolution seized the US Embassy in Tehran, taking American diplomats and staff hostage. The immediate trigger was the Carter administration’s decision to allow the exiled Shah into the United States for medical treatment. The Iran hostage crisis lasted 444 days, from November 4, 1979, until January 20, 1981. During this period: The United States imposed economic sanctions and froze Iranian assets. Diplomatic efforts to negotiate a release repeatedly stalled. In April 1980, a US military rescue mission, Operation Eagle Claw, failed after equipment malfunctions and a fatal collision in the Iranian desert, resulting in the deaths of eight American service members. The hostages were finally released on January 20, 1981, minutes after Ronald Reagan was inaugurated as president, following negotiations mediated by Algeria. The crisis had a lasting effect on American public opinion toward Iran and cemented a period of open hostility between the two governments. Iran-US Relations After 1980 The United States formally severed diplomatic relations with Iran in April 1980, and no formal diplomatic ties have been restored since. Switzerland has represented US interests in Iran, while Pakistan has represented Iranian interests in Washington. During the 1980s, tensions were compounded by the Iran-Iraq War (1980–1988), in which the United States provided intelligence and other support to Iraq for parts of the conflict, while separately becoming entangled in the Iran-Contra affair, a covert and controversial arms-for-hostages arrangement involving Iran. Throughout the 1990s, Washington maintained sanctions on Iran and classified it as a state sponsor of terrorism, a designation that remains in place. Iran’s Nuclear Program and US-Iran Negotiations Concerns over Iran’s nuclear program became a central issue in US-Iran relations starting in the early 2000s, after previously undisclosed nuclear facilities were revealed. The United States and other countries, including the UK, France, Germany, Russia, and China, grew concerned that Iran might be pursuing nuclear weapons capability, despite Iran’s insistence that its program was for peaceful energy purposes. Throughout the 2000s and early 2010s, the United Nations Security Council and Western governments imposed escalating sanctions targeting Iran’s oil exports, banking sector, and nuclear-related activities. Multiple rounds of negotiations, often called the P5+1 talks, sought a diplomatic resolution. The 2015 Iran Nuclear Deal These negotiations culminated in July 2015 with the Joint Comprehensive Plan of Action (JCPOA), commonly known as the Iran nuclear deal. Under the agreement, Iran agreed to significant limits on its nuclear activities, including uranium enrichment levels and stockpiles, in exchange for relief from many international sanctions. The JCPOA was negotiated between Iran and the P5+1 group: the United States, United Kingdom, France, Germany, Russia, and China, along with the European Union. It was widely regarded as a major milestone in Iran nuclear deal history and a rare example of sustained diplomatic engagement between Tehran and Washington since 1979. US Withdrawal From the JCPOA The agreement’s stability did not last. In May 2018, President Donald Trump announced that the United States would withdraw from the JCPOA, arguing that it failed to adequately address Iran’s missile program and regional activities. Washington reimposed sweeping sanctions under a policy known as “maximum pressure.” Iran initially continued complying with parts of the agreement but gradually reduced its commitments in response, including increasing uranium enrichment beyond the deal’s limits. The withdrawal deepened mistrust and set off years of renewed economic and diplomatic strain. Iran-US Relations in Recent Years Since 2021, diplomatic efforts to revive some version of the nuclear agreement have continued intermittently without a lasting breakthrough. Indirect US-Iran talks, often mediated by Oman, resumed in 2025 under the Trump administration, focused on limiting Iran’s nuclear program and missile capabilities. These negotiations were disrupted in mid-2025 after Israeli strikes on Iranian nuclear and military sites led to a broader Iran-Israel conflict, which halted talks entirely. Diplomatic pressure continued through the year: in August 2025, European powers warned Iran that they would trigger the JCPOA’s “snapback” mechanism, and by late September 2025, United Nations sanctions on Iran were formally reimposed after Security Council efforts to delay the move failed. Tensions escalated further in early 2026, when the United States and Israel launched military strikes against targets inside Iran in late February 2026, following the collapse of extended negotiations. Despite the strikes, the two countries did not enter a formal state of war. Diplomacy resumed afterward, with Iranian and American negotiators meeting for renewed nuclear talks in Geneva. By June 2026, the US and Iran had reached a memorandum of understanding committing both sides to negotiate a broader agreement covering the nuclear program and sanctions within a set timeframe. As of mid-2026, a comprehensive, lasting settlement between Washington and Tehran had not yet been finalized, and the relationship remains defined by cycles of negotiation, sanctions, and periodic military confrontation.
