No War Against Iran Act

S 2087, the "No War Against Iran Act," prohibits the use of federal funds for any military action in or against Iran without explicit congressional approval. It requires Congress to either declare war or pass specific new authorization for such action after this bill's enactment, overriding prior authorizations like the Iraq AUMF. The bill does not block self-defense actions if Congress later authorizes them under the War Powers Resolution, but it maintains existing reporting and consultation requirements for the executive branch. This directly affects the President and Pentagon, requiring congressional consent before funding military operations targeting Iran.
