This joint resolution mandates the termination of United States Armed Forces' involvement in hostilities against the Islamic Republic of Iran , its government, or military, unless Congress explicitly authorizes such action through a declaration of war or specific authorization for use of military force. It emphasizes that Congress possesses the sole constitutional authority to declare war and has not yet granted such authorization for actions against Iran. The resolution asserts that current U.S. military actions against Iran constitute hostilities under the War Powers Resolution, necessitating congressional approval. It aims to ensure that any decision regarding military engagement with Iran follows a full briefing, public debate, and a congressional vote as outlined in the Constitution. This directive does not, however, prevent the United States from defending itself against an imminent attack.
