USA-Iran peace talks in Islamabad failed on April 12, 2026, without a deal, as a 14-day ceasefire neared its end. US Vice President JD Vance described the offer as "final and best," but key disagreements persisted.
Why the Talks Failed:
Nuclear Guarantees: The US demanded verifiable assurances that Iran would not pursue nuclear weapons. Iran refused these terms.
Hormuz Control: Conflict continued over Iran's military control of the Strait of Hormuz, which the US insists must be reopened.
Pace of Diplomacy: Iran resisted the rapid timeline of a one-session deal, describing US demands as excessive.
