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. It emphasizes the need for Congressional oversight and limits the President's ability to engage in military action without explicit approval from Congress. Key provisions of the resolution include a clear directive for the President to remove U.S. Armed Forces from conflicts with Iran. However, it allows for exceptions where military personnel may remain if they are needed to defend the U.S. or its allies from an immediate threat.
