Outstanding collection of essays by significant figures on a particularly timely issue. The book is organized in two major sections: Part one, "The Nature of Terrorism," provides an overview and foundation for the current campaign, placing it within the political and historical context of previous threats and responses. Part two, "The Responses to Terrorism," looks at the range of policy instruments required in an effective strategy against terrorism. Included here are analysis of how these instruments--such as diplomacy, intelligence, psycho-political means, international law, criminal law enforcement, military force, foreign aid, and homeland security--are currently being employed. This book provides a comprehensive picture of the challenges and opportunities of the campaign against international terrorism. Contributors include Paul Pillar, a well-published scholar now with the the National Intelligence Council (CIA); Martha Crenshaw of Wesleyan University; David Rapaport, professor emeritus of political science at UCLA and creator of the "four waves" theory of terrorism; Adam Roberts of Oxford; and Detective Chief Inspector Lindsay Clutterbuck of the New Scotland Yard.
