Authorization to Use Military Force (AUMF)

The US Congress adopts a joint resolution, the Authorization for Use of Military Force (AUMF), that determines that “the president is authorized to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons.” Congress also states that the “grave acts of violence” committed on the US “continue to pose an unusual and extraordinary threat to [its] national security and foreign policy.” [US Congress, 9/14/2001] President Bush signs the resolution into law on September 18. [White House, 9/18/2001] The passage of the AUMF served another purpose: to extend presidential power. While the Defense Department and the Joint Chiefs of Staff intended the AUMF to define the conflict in narrow terms, and authorize the US to move militarily against al-Qaeda and its confederates, and the Taliban, Vice President Dick Cheney and his chief of staff, David Addington, had a larger goal. Attorney Scott Horton, who has written two major studies on interrogation of terrorism suspects for the New York City Bar Association, says in 2005 that Cheney and Addington “really wanted [the AUMF defined more broadly], because it provided the trigger for this radical redefinition of presidential power.” Addington helped draft a Justice Department opinion in late 2001, written by lawyer John Yoo (see Late September 2001), that asserted Congress cannot “place any limits on the president’s determinations as to any terrorist threat, the amount of military force to be used in response, or the method, timing, and nature of the response.” [US News and World Report, 5/21/2006]
