The latest round of high-stakes peace negotiations between the United States and Iran hosted in Islamabad concluded on Sunday with no breakthrough deal to show for days of intensive diplomatic engagement, U.S. Vice President JD Vance, who led the American delegation to the talks, confirmed to reporters on Sunday. The lead U.S. negotiator announced that the American delegation would now return to Washington, noting that Tehran ultimately rejected the terms put forward by the U.S. negotiating team. Vance also highlighted that disagreements over Iran’s nuclear program remain one of the most critical and unresolved points of contention between the two sides, leaving no path to a consensus after the closed-door negotiations. The discussions, which were held in the Pakistani capital, marked another high-profile diplomatic push to ease long-running tensions between Washington and Tehran, but failed to deliver the tangible progress that international observers had hoped for.
