The common American tendency to view the outside world in starkly divided Manichean terms between friends, allies and good guys on one side and adversaries and evil-doers on the other side arises in many circumstances but seems especially marked in discussions of terrorism. The tendency is most visible in how the lists that have become mainstays of counterterrorist policy are widely perceived. The U.S. list of foreign terrorist organizations had an almost mundane purpose when it was established by the Antiterrorism and Effective Death Penalty Act of 1996. One of the principal features of that legislation was to criminalize the provision of material support to any foreign terrorist organization. This made necessary clear definitions not only of material support but also of foreign terrorist organizations. Hence the creation of the list, entries on which are determined by the secretary of state with the participation of other executive departments and according to criteria specified in the statute.
