01 · The brief

This proposed constitutional amendment would require that any Act of Congress (after ratification) authorizing the use of U.S. military force outside the United States, when not accompanied by a declaration of war, automatically expire on the earlier of five years after enactment or the authorization’s own termination date.

Passage8/100

Constitutional amendments rarely pass; despite narrow clarity, securing two-thirds in both chambers and three-fourths state ratification is a very high bar.

CredibilityPartially aligned

Relative to its intended legislative type, this bill crisply imposes a prospective constitutional limit on the duration of future congressional authorizations of the use of military force outside the United States, but it leaves several practical and definitional gaps unaddressed.

Contention70/100

Liberals prioritize restoring congressional oversight; conservatives prioritize military flexibility.
