The involvement of insurgent and extremist groups in criminal activity is an issue that has been a concern of U.S. administrations for decades. In recent years, some observers have claimed that interactions between international terrorists and criminals are increasing. If true, expanded links between criminal and terrorist networks could increase U.S. vulnerability to attack by terrorist groups with enhanced criminal capabilities and financial resources. An expanded range of combined criminal and terrorist activity could also affect the global economy and U.S. foreign policy goals. This new book examines the security threats and U.S. policy regarding international terrorism and transnational crime, and also looks at the terrorism hot spots of Latin America, Southeast Asia and Somalia.
