Iraq, Syria, and Somalia.
2001 Authorization for Use of Military Force (2001 AUMF)
Foreign Forces, Irregular Forces, Groups, or Individuals for Which a Determination Has
Been Made That Force Could Legally Be Used Under the Authorization for Use of Military
Force, Pub. L. No. 107-40, 115 Stat. 224 (2001): No change.
Criteria for Designating a Foreign Force, Irregular Force, Group, or Individual as
Lawfully Targetable, as a High-Value Target, and as Formally or Functionally a Member of a
Group Covered Under the 2001 AUMF: No change.
Application of Key Domestic and International Legal Principles to Key Theaters
Afghanistan: As directed by President Biden, U.S. forces withdrew from Afghanistan
completely by August 31, 2021. The withdrawal of U.S. forces from Afghanistan did not change
the legal and policy frameworks for the use of military force in Afghanistan. Although the
United States is prepared to use force against al-Qa’ida, ISIS, and other terrorist threats in
Afghanistan, if necessary, utilizing U.S. forces and assets based outside Afghanistan, the
United States has not done so since the withdrawal of U.S. forces. The United States continues
to monitor terrorist groups located in Afghanistan.
