The main purpose of this legislative proposal is to amend the U.S. Constitution to set a limit on how long Congress can authorize the use of military force outside the United States without a formal declaration of war. The goal is to ensure that such authorizations do not remain in effect indefinitely and to promote accountability in military engagements. The key provision of this amendment states that any Act of Congress that allows for military force outside the U.S. will automatically expire five years after it is enacted, unless the Act itself specifies an earlier end date.
