US military operations against Iran, including large-scale strikes beginning February 28, 2026, and subsequent air campaigns targeting nuclear and missile facilities, have proceeded without a congressional declaration of war. A Pakistan-mediated ceasefire took effect in early April, though it remains fragile amid continued US troop deployments in the region, Iranian threats to maritime routes like the Strait of Hormuz, and ongoing diplomatic negotiations. President Trump has stated that military objectives are largely met while emphasizing that any final agreement must be unconditional, with recent comments in mid-May indicating the conflict could conclude peacefully or through further action. Congressional approval for a formal war declaration has not been sought, consistent with historical patterns of executive-led military engagements. Upcoming talks and potential deadlines for compliance could influence whether Congress acts before any market resolution date.
