Despite ongoing U.S. and Israeli military operations against Iran since February 28, 2026—including strikes that killed Supreme Leader Ali Khamenei and targeted nuclear and missile sites—Congress has not issued a formal declaration of war, and operations have proceeded under executive authority subject to the War Powers Resolution. Recent developments center on de-escalation: U.S.-Iran talks mediated by Pakistan produced an agreed draft text by June 11-12 for a ceasefire extension, Strait of Hormuz reopening, and blockade lift, with a potential signing targeted for mid-June. Iran has signaled openness while asserting leverage on nuclear issues to follow separately. These diplomatic steps, alongside congressional resolutions attempting to constrain further action, shape trader views that a formal war declaration faces high procedural and political barriers in the near term. Scheduled events include any final deal implementation or renewed strikes if talks collapse.
