The War Powers Resolution (50 U.S.C. ch. 33) is a federal law Congress enacted in 1973 over President Nixon's veto. It requires the president to consult Congress before committing U.S. armed forces to hostilities or situations where hostilities are imminent. Once forces are deployed, the president must notify Congress within 48 hours.
From that notification, a 60-day clock starts running. Unless Congress declares war, passes an AUMF, or extends the deadline, the president must withdraw all forces within 60 days. A 30-day extension is available only for safe withdrawal operations. Congress can also direct withdrawal through a concurrent resolution at any time.
Every president since Nixon has disputed the law's constitutionality, arguing that the commander-in-chief power under Article II doesn't require congressional pre-approval for military operations. Congress has never successfully enforced the 60-day withdrawal deadline through the courts. This standoff means the resolution functions more as a political pressure tool than a legally enforceable constraint.
The War Powers Resolution is the primary mechanism Congress has to check presidential war-making. Whether it actually works depends on political will — presidents routinely ignore its requirements, and Congress rarely forces the issue. Understanding this gap between the law's text and its enforcement reveals how war powers really operate in practice.
Many people assume the War Powers Resolution prevents the president from starting a war without Congress. It doesn't — it allows the president to deploy forces first and notify Congress after. The law's real mechanism is the 60-day withdrawal clock, which no president has ever been forced to obey.
