High-level talks between Iran and the United States in Islamabad, held over the course of 21 hours, ended without a resolution, leaving the future of a contested two-week ceasefire in question, according to the BBC.

Complex Issues and Deep Distrust

The historic negotiations, which took place during a pause in weeks of intense conflict, were always unlikely to end with a breakthrough, given the long-standing tensions between the two nations, according to the BBC.

The talks aimed to address complex issues, including Iran’s nuclear program and the control of the strategic Strait of Hormuz, whose closure has caused economic shocks worldwide, according to the BBC.

The negotiations also needed to overcome a deep chasm of distrust, which has persisted for decades, according to the BBC.

Final Offers and Unanswered Questions

US Vice-President JD Vance declared the US delegation had made their ‘final and best offer’ before departing Islamabad at sunrise, according to reports from sources in Islamabad, as cited by the BBC.

Vance described the ‘core goal’ of the US as needing an ‘affirmative commitment’ from Iran that it would not seek a nuclear weapon or the tools to achieve one quickly, according to the BBC.

Iran had previously offered concessions, including the dilution of its 440kg stockpile of uranium enriched to 60%, dangerously close to weapons-grade, according to the BBC.

However, Iran still insists on its ‘right’ to enrich uranium, and the stockpile is now reportedly buried deep in the rubble after US and Israeli air strikes last year, according to the BBC.

Iran also refused repeated demands to open the Strait of Hormuz, allowing the free flow of vital traffic in oil, gas, and other essential goods, according to the BBC.

Uncertain Path Forward

Both the US and Iran entered the talks believing they were the winning side in the conflict, according to the BBC.

Dr. Sanam Vakil of Chatham House noted a ‘limited psychological understanding of the adversary’ on both sides, according to the BBC.

Vance stated that there had been ‘a number of substantive negotiations’ but that ‘we have not reached an agreement,’ according to the BBC.

He emphasized that this was ‘bad news for Iran much more than the United States of America,’ according to the BBC.

Iran’s foreign ministry spokesman Esmail Baghaei criticized the US’s ‘excessive demands and unlawful requests’ in a post on X, according to the BBC.

Iran’s parliamentary speaker Mohammad Bagher Ghalibaf, who led the Iranian delegation, stated that ‘the opposing side ultimately failed to gain the trust of the Iranian delegation in this round of negotiations,’ according to the BBC.

Pakistan’s Foreign Minister Ishaq Dar urged all sides to uphold the fragile ceasefire and continue efforts to encourage dialogue, according to the BBC.

History offers a precedent: the 2015 Iran nuclear deal took 18 months of breakthroughs and breakdowns before it was finalized, according to the BBC.

President Donald Trump has made it clear he does not want to get bogged down in protracted negotiations, and Vance previously warned the US would not be receptive if Tehran tried to ‘play us,’ according to the BBC.

Pakistani journalist Kamran Yousef described the talks as one of ‘no breakthrough but no breakdown either,’ according to the BBC.

The world now waits for a verdict on the future of the ceasefire and the path forward, according to the BBC.
