US–Iran peace talks in Islamabad have ended without an agreement after more than 21 hours of negotiations, leaving a fragile two‑week ceasefire and global shipping through the Strait of Hormuz in limbo. Vice President J.D. Vance, who led the US delegation, said Iran “chose not to accept our terms,” while Iranian officials accused Washington of trying to secure at the table what it had “failed to achieve on the battlefield.”

“No agreement”: how the talks collapsed
The Islamabad talks were the first high‑level, face‑to‑face negotiations between Washington and Tehran since war erupted six weeks ago following a US–Israeli operation that killed Iran’s supreme leader, Ayatollah Ali Khamenei, and triggered Iranian missile strikes across the region. Hosted by Pakistan’s Prime Minister Shehbaz Sharif and army chief Field Marshal Asim Munir, the meeting brought together Vice President J.D. Vance and Iran’s delegation led by parliamentary speaker Mohammad Bagher Ghalibaf and Foreign Minister Hossein Amir‑Abdollahian.
After more than 21 hours of talks in a secure Islamabad compound, Vance emerged before dawn on Sunday to confirm there was no deal.
“The unfortunate news is that no agreement has been achieved,” he told reporters on the tarmac before boarding Air Force Two. “Iran has chosen not to accept our terms. That is bad news for them, far more than for the United States.”
According to Reuters and AP, the talks broke down primarily over US demands for an explicit Iranian pledge never to pursue a nuclear weapon, a condition Tehran refused to formalize beyond existing statements that its program is peaceful. US officials also wanted Iran to fully reopen the Strait of Hormuz to commercial shipping and to halt arms transfers and attacks by allied groups, including Hezbollah and Iraqi militias.
Iran’s delegation pressed for a permanent end to Israeli strikes on Hezbollah in Lebanon, the unfreezing of billions of dollars in Iranian assets held abroad, formal US assurances about future nuclear talks, and recognition of its right to levy transit charges on vessels passing Hormuz.
Dueling narratives from Washington and Tehran
Within hours of the breakdown, both sides sought to frame the failure as the other’s responsibility.
In Islamabad, Vance repeatedly stressed that Washington came with a “serious and generous” offer that would have extended the two‑week ceasefire, restored full shipping through the strait, and created a roadmap for broader de‑escalation. “We were prepared to give Iran significant sanctions relief over time if they met clear benchmarks: no nuclear weapon, no attacks on our troops, no more rockets from Hezbollah into Israel,” he said.
Iranian officials offered a starkly different account. Ghalibaf told Iran’s state‑aligned Fars news agency that the “worse news is for the United States,” arguing that Washington had “initiated the talks, chosen the mediator and agreed to Iran’s ten prerequisites” but still tried to “obtain at the negotiating table what it failed to achieve on the battlefield.”
A source close to the Iranian team told CNN that Tehran had “no plan for a next round of negotiations” and would make no changes at Hormuz until the US accepted “a fair agreement” that addressed Israel’s operations in Lebanon and long‑standing US sanctions. Iran also bristled at what it called “maximalist” US nuclear language that went beyond the Non‑Proliferation Treaty and past commitments.
Pakistan’s risky bet on mediation
For Pakistan, the collapse is a diplomatic and strategic setback after Islamabad gambled heavily on hosting the talks.
US President Donald Trump had announced the two‑week ceasefire on Tuesday, crediting Sharif and Munir with persuading Washington to pause airstrikes in exchange for a chance at a negotiated opening of Hormuz. Pakistan’s leadership, facing economic crisis and volatile western provinces bordering Iran, cast the talks as an act of “strategic self‑preservation” as much as statesmanship.
Analysts quoted by India Today warned even before the breakdown that Islamabad would face a “nightmare scenario” if the mediation failed and Pakistan were dragged into a wider war because of its mutual defense pact with Saudi Arabia, Tehran’s regional rival. “Sitting at the crossroads of South Asia, Central Asia and the Middle East, Pakistan is directly exposed to any escalation involving Iran,” one expert said, noting that pressure from Riyadh could mount if the conflict reignites.
With Vance now back in Washington and Iran ruling out an immediate return to the table, Pakistan is left managing frayed expectations at home and the risk that fighting across the Gulf could again spill toward its borders.
Ceasefire and Hormuz: what happens now?
The most immediate questions after the failed talks concern the two‑week ceasefire and the Strait of Hormuz, a chokepoint for roughly a fifth of the world’s traded oil and a major share of global liquefied natural gas.
Trump’s ceasefire announcement halted US strikes in exchange for what he described as Iran’s agreement to “the complete, immediate and safe opening of the Strait of Hormuz.” In practice, shipping companies have remained cautious, with traffic still “severely disrupted” by security concerns, insurance costs and uncertainty over how far Iranian forces would go to enforce their leverage.
US officials told AP and NBC that, for now, Washington will maintain the ceasefire while reviewing options, but warned that “all responses are on the table” if Iran resumes missile or drone attacks on US forces or closes Hormuz to tankers. Iran, for its part, has signaled that the status quo in the strait will not change in its favor until the US offers what it calls “balanced concessions.”
Markets reacted nervously to the news from Islamabad, with Brent crude prices ticking higher in early trading and shipping analysts warning that any renewed threat to Hormuz could quickly feed into global inflation.
Sticking points: nuclear guarantees, Israel, and money
Behind the public soundbites, several substantive gaps doomed the Islamabad round.
Nuclear pledge: The US wanted a clear, binding commitment that Iran would “never seek, develop or acquire a nuclear weapon,” with verification measures beyond the 2015 nuclear deal, in exchange for phased sanctions relief. Iran insisted its religious decree (fatwa) against nuclear weapons and its treaty obligations were sufficient and balked at language it saw as humiliating and one‑sided.
Regional militias and Israel: Washington pushed Iran to rein in Hezbollah and other allied groups, tying a lasting ceasefire to an end to rocket fire on Israel and attacks on US forces in Iraq and Syria. Tehran demanded an end to Israeli strikes on Hezbollah positions in Lebanon as part of any package, something the US delegation said it could not fully guarantee on Jerusalem’s behalf.
Sanctions relief and frozen assets: Iran sought the unfreezing of tens of billions of dollars in assets held abroad and concrete timelines for lifting key US sanctions. Vance’s team reportedly offered limited unfreezing and sectoral relief tied to compliance over time, which Tehran dismissed as insufficient.
Hormuz tolls and sovereignty: Iranian negotiators pressed for recognition of their right to levy fees on ships using the Strait of Hormuz, a demand US officials saw as an unacceptable precedent for weaponizing global commons.
With neither side willing to absorb the political cost of compromise on those issues, the Islamabad round became, in effect, a high‑stakes blame game.
What failure means for Washington, Tehran, and the world
In Washington, the collapse is a blow to President Donald Trump’s bid to show he can end the war he helped ignite while keeping Iran “permanently away from the bomb.” Vance’s prominent role in the talks had also been seen as a test of his foreign‑policy credentials as vice president and potential future presidential contender.
For Tehran’s leadership, walking away without a deal allows it to project defiance and avoid concessions that might be portrayed as surrender, especially after the shock of Khamenei’s killing. But it leaves Iran facing continued economic pressure, the uncertainty of a tenuous ceasefire and the risk that a miscalculation at sea or along Israel’s borders could trigger a new round of strikes.
For Pakistan and other regional states, the failure deepens fears of a protracted shadow war around Hormuz, with sporadic clashes, cyberattacks and proxy strikes but no comprehensive de‑escalation framework.
Globally, the outcome underscores how difficult it will be to disentangle the immediate ceasefire question from longer‑running disputes over Iran’s nuclear program, its regional alliances, and US sanctions. As one analyst told NPR, “You can’t fix Hormuz in a weekend if you’re also trying to fix 20 years of mistrust.”
For now, the most that Islamabad delivered was a photo‑op of adversaries at the same table, and a reminder that, even with guns briefly quieter, the political distance between Washington and Tehran remains stubbornly wide.
