What is the War Powers Resolution passed in 1973?

The War Powers Resolution, enacted in 1973, is a federal law aimed at checking the president's power to commit the United States to armed conflict without congressional consent. It requires the president to notify Congress within 48 hours of deploying military forces and limits military engagement to 60 days without a declaration of war or authorization from Congress. The resolution was enacted in response to concerns over the Vietnam War and the executive branch's unilateral military decisions. While it sought to restore legislative authority over military actions, its effectiveness and adherence have been subjects of ongoing debate.
