The "No War Appropriations through Reconciliation Act" (No WAR Act) amends the Congressional Budget and Impoundment Control Act of 1974 to establish a new point of order. This procedural mechanism aims to prevent the use of reconciliation measures to fund unauthorized military operations against Iran. Specifically, it makes it out of order in both chambers to consider any reconciliation bill, resolution, amendment, or conference report that appropriates or provides budget authority for hostilities against the Islamic Republic of Iran. This point of order applies unless Congress has explicitly authorized such hostilities through a formal declaration of war or a specific Authorization for Use of Military Force (AUMF). The bill broadly defines "hostilities" to include offensive military operations, strikes, covert actions, or sustained armed conflict against Iranian military forces, territory, or government institutions, including actions conducted by a "proxy force" operating with U.S. direction or support.
