April 12, 2026 — Islamabad Talks Collapse.
Historic Talks End in Failure
The highest-level face-to-face negotiations between the United States and Iran since the 1979 Islamic Revolution ended without an agreement on April 12, 2026, after 21 hours of marathon talks at Islamabad's Serena Hotel. Vice President JD Vance, who led the 300-member U.S. delegation, told reporters before departing Pakistan that Iran had 'chosen not to accept our terms.'
The core impasse centered on Iran's nuclear program. The U.S. demanded an 'affirmative commitment' that Iran would not pursue nuclear weapons or the tools to quickly build them. Iran, represented by Parliamentary Speaker Mohammad Bagher Ghalibaf, insisted on maintaining its enrichment capabilities and blamed Washington for making 'unreasonable demands.'
Pakistan's PM Sharif urged both sides to continue diplomacy despite the breakdown, calling the ceasefire 'imperative' for regional stability.
