From the Document: "Afghanistan's geography, complex ethnic composition, and history of conflict and instability have created space for numerous armed Islamist groups, some of which engage in transnational terrorist activity. This product outlines major terrorist groups present in Afghanistan that are affiliated and allied with Al Qaeda (AQ) and the Islamic State (IS, also known as ISIS, ISIL, or by the Arabic acronym 'Da'esh'), and relations between these groups and other actors, most notably the Taliban. These dynamics may inform assessments of U.S. policy in Afghanistan in light of the Taliban's renewed control of the country. The Taliban interact with the groups below in varying ways that may affect U.S. interests. Observers differ on how Taliban rule might empower or undermine these terrorist groups or Taliban behavior toward them. U.S. public assessments of the threats these groups pose to U.S. interests, including to the U.S. homeland, vary. President Joseph Biden and other U.S. officials have stated that the United States will maintain 'over-the-horizon' capabilities to address terrorist threats in Afghanistan. As of mid-March 2022, the United States has not carried out any such strikes since the U.S. military withdrawal was completed on August 30, 2021."
