Editor’s Note: The war against terrorism involves fighting more than terrorists. Some groups use guerrilla war, and still others are proto-states. The post-9/11 struggle has also brought the United States into greater contact with warlords, clans, and other non-state actors. Daveed Gartenstein-Ross and Jacob Zenn of the Foundation for the Defense of Democracies and the Jamestown Foundation, respectively, try to bring a sense of order to these many actors, offering a spectrum of "violent non-state actors" as a way to better conceptualize them.
