Since 9/11, international cooperation against international terrorism has improved. However, the global community is still far from a situation in which one country's terrorist group is all countries' public enemy. This comparative list enumerates 120 extremist/terrorist groups blacklisted by six countries and two international organizations. The listings highlight the security interests, priorities, and outlook of particular countries and international organizations. Each individual list reflects regional or, in some instances, global, security concerns of the designating country/body and, therefore, there is less overlap than anticipated.
