Diplomatic talks in Islamabad ended without a deal, with each side blaming the other after a marathon session failed to resolve the crisis that began six weeks earlier with US‑Israeli strikes on Iran.
US officials said negotiations stalled because Iran would not provide an explicit commitment to forgo a nuclear weapons program and the means to build one quickly. Speaking after the meeting, Vice President JD Vance said Washington needed “an affirmative commitment” that Iran would not pursue a weapon or the tools to accelerate its development.
Iranian representatives, including parliamentary speaker and delegation head Mohammad Bagher Qalibaf, blamed the United States for the impasse and urged Washington to demonstrate it could be trusted. Tehran’s state and semi‑official outlets described US demands as “excessive,” while some reported partial agreement on limited issues but sharp disagreement over the nuclear question and control of the Strait of Hormuz.
The Islamabad talks were the first direct, high‑level face‑to‑face engagement between Washington and Tehran in more than a decade and the most senior contact since Iran’s 1979 revolution. They followed a fragile ceasefire declared days earlier in a conflict that has killed thousands and rattled international markets.
After the breakdown, US President Donald Trump said the US Navy would impose a blockade on the Strait of Hormuz, a move underscoring the strategic tensions at the center of the negotiations. Pakistan’s foreign minister, Ishaq Dar, urged both parties to preserve the ceasefire and continue diplomacy, calling the truce “imperative” for any further progress.
Analysts say the core problem was a mismatch in fundamental objectives. The United States sought limits on Iran’s nuclear program, broader regional de‑escalation and secure maritime transit, while Iran sought sanctions relief, formal recognition and guarantees against future pressure. Fatemeh Aman, an Iran‑Pakistan expert at the Atlantic Council, described the disagreement as structural rather than simply tactical: each side wanted the other to make the first, verifiable concession.
Farwa Aamer of the Asia Society Policy Institute said the talks opened a necessary channel of communication but that building mutual understanding will take time. With mutual distrust and competing leverage, neither side was willing to accept the immediate tradeoffs the other demanded, she said.
Despite the failed session, some analysts are cautiously optimistic the ceasefire can hold in the short term, aided by backchannel diplomacy and international mediators. Aman warned, however, that the truce is fragile and based on short‑term calculations; without sustained follow‑up, local incidents, miscalculation or actions by allied groups could rapidly erode restraint.
Expectations are that there will be a pause while both capitals reassess positions and domestic political considerations. If negotiations resume, they are likely to start with narrower, technical confidence‑building measures rather than sweeping concessions. Quiet diplomacy and mediation are expected to remain critical to prevent a return to open conflict.
