US-Iran nuclear negotiations collapse; Vance cites weapons disagreement in Pakistan
US Vice President JD Vance announced in Islamabad on April 12, 2026, that negotiations with Iran over ending hostilities have failed, with the core dispute centered on Iran's nuclear weapons program—which Iran denies developing. Iranian state media attributed the breakdown to "unreasonable demands" from the United States. The collapse represents a significant setback in efforts to de-escalate US-Iran tensions at a time when both countries remain in direct diplomatic engagement. President Trump made related statements to reporters hours before Vance's announcement.
