This joint resolution mandates the removal of United States Armed Forces from any hostilities within or against the Islamic Republic of Iran, unless such actions are explicitly authorized by a congressional declaration of war or a specific authorization for the use of military force . It emphasizes that Congress holds the sole constitutional power to declare war and notes that no such authorization currently exists for military engagement with Iran. The resolution asserts that any use of military force against Iran constitutes "hostilities" under the War Powers Resolution , triggering expedited legislative procedures for its consideration. However, it includes a crucial rule of construction, clarifying that its provisions do not impede the United States from defending against attacks on its personnel or facilities, or from collecting and sharing intelligence regarding threats from Iran or its proxies. Furthermore, the resolution permits the U.S. to assist partner countries attacked by Iran since February 28, 2026, by helping intercept retaliatory attacks or providing defensive materiel support.
