The main purpose of this legislative text is to repeal the Authorization for Use of Military Force (AUMF) that was enacted in 2001. This law has allowed the U.S. government to engage in military actions without a formal declaration of war from Congress. The objective of this new legislation is to limit the executive branch's ability to conduct military operations under this broad authorization, reinforcing Congress's constitutional role in declaring war. Key provisions of this legislation include the formal repeal of the AUMF after a 240-day period following its enactment.
