Hostilities between the US and Iran began on February 28, 2026, triggering the War Powers Resolution's 60-day withdrawal requirement, with the deadline passing on May 1 without congressional authorization. A ceasefire reportedly started on April 7 and has been extended, with no direct fire exchanged since, though recent air defense activations occurred in Tehran and tensions persist over naval positions in the Strait of Hormuz. US officials claim the truce pauses the legal clock, while Iran maintains a chokehold on the strait and a UK-France security mission advances.
