U.S.-Iran diplomatic talks in Pakistan end without an agreement

Diplomatic negotiations between the United States and Iran concluded in Islamabad, Pakistan, on April 12, 2026, after 21 hours of discussions aimed at ending the conflict in the Middle East. The U.S. delegation, led by Vice President J.D. Vance, left for Washington without a deal, stating that they had offered their best possible proposal. Key points of contention included the Iranian nuclear program, navigation rights in the Strait of Hormuz, international sanctions, and war reparations. While the U.S. side emphasized its clear 'red lines' regarding Iran's nuclear activities, Iranian officials accused the U.S. of making excessive demands. Pakistan served as a mediator, with Prime Minister Shehbaz Sharif hosting both delegations in an attempt to bridge the gap. Iran's representatives claimed that prior agreements regarding a ceasefire in Lebanon and the unfreezing of Iranian assets had not been fully implemented. Both sides acknowledged that the lack of a deal is a negative development, though they differ on who carries the greater burden. The discussions were described as substantive but ultimately failed to reconcile the fundamental differences between the two nations.
