The main purpose of this resolution is to direct the President of the United States to withdraw American military forces from any hostilities involving Iran. This action is taken under the authority of the War Powers Resolution, which is a law that outlines the President's powers in military engagements and Congress's role in authorizing such actions. The key provisions of this resolution state that the President must remove U.S. Armed Forces from conflicts with Iran, except for those forces that may be needed to protect the U.S. or its allies from an immediate threat.
