From the Document: "Afghanistan's geography, complex ethnic makeup, and recent history of conflict, instability, and decentralized government have created space for the activities of a number of regional armed groups. This product outlines major terrorist groups 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 the complex, often shifting relations between them and various other state and non-state actors. These dynamics may inform assessments of U.S. policy in Afghanistan in light of ongoing U.S.-Taliban negotiations focused largely on counterterrorism concerns. The Afghan Taliban is not a U.S.-designated Foreign Terrorist Organization (FTO), but it relates to the groups below in varying ways that may have ramifications for those negotiations."
