US-Iran Peace Talks Collapse After 21-Hour Marathon in Islamabad
Historic face-to-face negotiations between the United States and Iran have ended without a deal after a gruelling 21-hour session in Islamabad, Pakistan, throwing the fragile two-week ceasefire into serious doubt and raising fears of renewed conflict in the Middle East.
Background
The talks, mediated by Pakistan, were the first direct high-level engagement between Washington and Tehran since Iran's 1979 Islamic Revolution. They followed a two-week ceasefire agreed on 7 April 2026, which had paused weeks of US and Israeli strikes on Iranian targets and Iran's blockade of the Strait of Hormuz — a critical chokepoint through which approximately one-fifth of global energy exports pass. The ceasefire had been brokered after President Trump threatened to destroy Iranian civilian infrastructure if the strait was not reopened.
Key Developments
The US delegation, led by Vice President JD Vance alongside special envoy Steve Witkoff and Jared Kushner, sat across from an Iranian team headed by Parliamentary Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi. Despite the marathon session, the two sides could not bridge fundamental differences.
Vance confirmed the breakdown, stating that the US had presented its "final and best offer" and had made clear its red lines, but Iran had "chosen not to accept our terms." The core US demand was an unambiguous commitment from Iran to permanently forgo nuclear weapons. Vance added that the failure was "bad news for Iran much more than it's bad news for the United States of America."
Iran's Ghalibaf blamed the collapse on a lack of trust, saying the US "failed to gain the trust of the Iranian delegation in this round of negotiations." Iranian state media attributed the breakdown to what it described as "excessive" and "unreasonable" US demands, including control over the Strait of Hormuz, war reparations, and limits on Iran's nuclear enrichment programme.
America has understood our logic and principles, and now it's time for it to decide whether it can earn our trust or not? — Mohammad Bagher Ghalibaf, Iranian Parliamentary Speaker
Points of Contention
Beyond the nuclear programme, the talks foundered on several other issues:
- Strait of Hormuz: Iran demanded the right to collect transit fees and maintain control of the waterway; the US insisted on free passage for all vessels.
- War reparations: Iran sought compensation for damage caused by US and Israeli strikes.
- Sanctions: Iran demanded the lifting of all economic sanctions as part of any deal.
- Lebanon ceasefire: Iran insisted any agreement must include a halt to Israeli strikes in Lebanon, which Israel disputes.
Iran's foreign ministry spokesperson Esmaeil Baghaei sought to downplay the failure, noting that "no one expected an agreement in a single session" and that contacts with Pakistan and other regional allies would continue.
Why It Matters
The collapse of the Islamabad talks leaves the two-week ceasefire in a precarious state. The Strait of Hormuz remains a flashpoint — Iran's blockade since the conflict began has sent global oil prices soaring and disrupted energy supplies worldwide. The UK and other European nations have significant economic exposure to Middle East energy markets, and any resumption of hostilities would have immediate consequences for fuel prices and inflation across Britain and Ireland.
UK Prime Minister Keir Starmer and the Sultan of Oman both voiced disappointment at the outcome and urged both sides to avoid further escalation. Russia's President Vladimir Putin spoke with Iranian President Masoud Pezeshkian, expressing Moscow's readiness to facilitate further dialogue.
What's Next
Pakistan's Foreign Minister Ishaq Dar urged both the US and Iran to uphold their commitment to the ceasefire and expressed readiness to facilitate new dialogue in the coming days. The US delegation has departed Islamabad, with no immediate resumption of direct talks scheduled. President Trump, who was in constant communication with Vance throughout the session, has previously stated that whether a deal is reached "makes no difference" to him, claiming the US had already "totally defeated" Iran militarily.
With the ceasefire clock ticking and no diplomatic breakthrough in sight, the coming days will be critical in determining whether the fragile peace holds or the region slides back toward open conflict.
