The War Powers Resolution requires consultation by the president the lawmakers deploying U.S. armed forces into active hostilities. it establishes 60 days unless Congress declares war, with extending and withdrawal needing ongoing congressional involvement and potential measures to remove troops. Originated to check executive war-making after Vietnam, but disputes remain about effectiveness and constitutional balance of powers. it provides a potential 30-day extension for withdrawal if safety concerns develop, and it remains a focus to continued discussion and proposals including efforts to adjust and clarify its procedures.
