This legislation establishes a framework for the automatic termination of congressional authorizations for the use of military force and declarations of war. Its primary goal is to ensure greater accountability and prevent prolonged military engagements without periodic reauthorization. Specifically, any new authorization for military force or declaration of war enacted after this bill becomes law would automatically expire 10 years after its enactment date. Furthermore, all existing authorizations for the use of military force or declarations of war that were enacted prior to this bill's passage would terminate within 6 months of this Act's enactment.
