An intense round of negotiations in Islamabad highlighted deep divisions between Washington and Tehran, with limited time proving insufficient to resolve decades of conflict

The latest round of US-Iran negotiations in Islamabad unfolded with urgency, ambition and, ultimately, limited results. Over the course of just 21 hours, two heavily staffed delegations attempted to tackle a dispute spanning more than two decades, compounded by the recent escalation of conflict and new geopolitical flashpoints.

Iran arrived with an extensive and carefully structured team, reportedly including members of the Islamic Revolutionary Guard Corps alongside specialists covering legal, economic, military and technical issues. Their preparation reflected a determination to safeguard gains achieved on the ground and avoid concessions at the negotiating table. Detailed proposals, including lengthy technical documents on nuclear safety, underscored the depth of their approach.

The United States, in turn, sent a significantly expanded delegation, led by Vice-President JD Vance and supported by hundreds of officials. The scale of the American presence suggested a recognition of Iran’s negotiating experience and a desire to engage more comprehensively than in previous rounds. Throughout the talks, Vance remained in close contact with President Donald Trump, highlighting the political sensitivity surrounding the discussions.

Yet the compressed timeframe quickly became a central obstacle. Expectations that such a complex and entrenched dispute could be resolved in a single marathon session proved unrealistic. Observers noted that earlier nuclear negotiations, including those leading to the 2015 agreement, required years of sustained diplomacy.

Fundamental disagreements persisted. The United States continued to press for firm guarantees that Iran would not pursue nuclear weapons capabilities, while Tehran resisted what it perceived as inflexible demands. Iranian officials and former diplomats criticised what they described as a “take-it-or-leave-it” approach, arguing that meaningful progress required mutual compromise rather than unilateral conditions.

Beyond the nuclear issue, several contentious points remained unresolved. These included the future governance of the Strait of Hormuz, a vital artery for global energy supplies, and the handling of Iran’s enriched uranium stockpile. Questions also lingered over broader regional dynamics, particularly ongoing tensions involving Israel and Lebanon.

Despite the absence of a breakthrough, both sides signalled that dialogue might continue. While Washington described its proposal as a “final offer,” the language used by officials left room for further engagement. Pakistan, which hosted the talks, urged both parties to keep diplomatic channels open amid concerns that failure could lead to renewed escalation.

Meanwhile, the strategic importance of the Strait of Hormuz has taken on renewed significance. Iran’s ability to influence shipping flows through selective permissions has emerged as a powerful—if unstable—lever in the broader conflict. This evolving dynamic has implications not only for regional security but also for global energy markets.

Underlying the مذاکرات is a broader test of resolve. After weeks of confrontation, both Washington and Tehran appear to be gauging each other’s limits, balancing domestic pressures with international expectations. For Iran, internal economic strain and political isolation add urgency to the search for relief, even as it seeks to preserve sovereignty and strategic leverage.

The Islamabad talks, while inconclusive, have clarified one point: the path to any durable agreement remains long and uncertain. In a conflict shaped by history, ideology and shifting alliances, 21 hours of diplomacy were never likely to be enough.
