US Vice President JD Vance left Islamabad Sunday after 21 hours of direct talks with Iran ended without agreement. The collapse centered on Iran's refusal to commit to permanently abandoning nuclear weapons development. Vance stated Washington needed long-term Iranian commitment against nuclear weapons. Iran's 10-point proposal sought war cessation, strait control, and asset compensation. The US presented 15 demands focusing on nuclear restrictions. Both sides blamed each other for negotiation failure.
