The Handbook of Terrorist and Insurgent Groups: A Global Survey of Threats, Tactics, and Characteristics examines the most current and dangerous terrorist and insurgent groups around the world. The purpose is to create a descriptive mosaic of what is a pointedly global security challenge. The volume brings together conceptual approaches to terrorism, insurgency, and cyberterrorism with substantive and empirical analyses of individual groups, organizations, and networks. By doing so, not only does the coverage highlight the past, present, and future orientations of the most prominent groups, but it also examines and illustrates their key characteristics and how they operate, including significant leaders and ideologues. The chapters provide a thorough and comprehensive overview of the current geography of terrorist and insurgency groups active in the world today. This comprehensive volume brings the collective expertise and knowledge of more than 50 academics, intelligence and security officials, and professionals together, all of whom are considered subject experts in their respective areas of research and practice. Specialists in these fields conducted both desk and field research for this volume, which includes analyses of secondary literature and primary data, such as first-person interviews concerning the operational regions, tactics, and ideological motivations of the various groups.
