War Powers

War powers divide authority over America’s military between the president and Congress. The president commands forces as Commander in Chief, while Congress declares war and controls funding.

The Constitutional Split

Presidents and Congress each have distinct war powers. This setup prevents unilateral wars, though presidents often act without explicit approval.

The War Powers Resolution

Enacted in 1973 after Vietnam, the War Powers Resolution requires notification within 48 hours and limits actions to 60 days without authorization, plus 30 days for withdrawal. Presidents frequently sidestep it, claiming actions fall outside its scope.

Presidential Actions Without Congress

Presidents can order cyberattacks, conduct strikes without ground troops, impose naval blockades, and invoke vague “imminent threat” doctrines for seizing territory.

Congressional Pushback

Congress can halt strikes with political unity, as seen in disputes over joint operations or senators breaking ranks.
