Paragraph 1: The Constitution deliberately splits control of military force to prevent any single branch from unilaterally committing the nation to war. Congress holds the power of the purse and the power to declare war; the president commands the armed forces but cannot declare war or spend money without congressional authorization.
Paragraph 2: In practice, presidents routinely deploy forces without formal declarations. President Truman sent troops to Korea in 1950 without a declaration; President Johnson escalated Vietnam with the Gulf of Tonkin Resolution; President Bush secured an authorization for the Iraq War. Each tested the bounds of executive power.
Paragraph 3: The War Powers Resolution of 1973 attempted to codify limits—requiring the president to notify Congress within 48 hours of committing armed forces and prohibiting sustained military action beyond 60 days without congressional authorization. Presidents have routinely ignored or sidestepped it, arguing it infringes executive authority. Courts have largely refused to enforce it, leaving the balance a matter of political negotiation rather than law.
When the military fights, Americans die and the nation's resources are consumed. The Framers wanted Congress—the body closest to voters—to make that choice, not a single executive. The tension between these powers has shaped major foreign policy decisions and defines how America goes to war.
People often think the president can declare war. In practice, only Congress can declare war; the president can direct military operations but needs money from Congress to sustain them.
