Overview

This book tells the story of how Al Qaeda grew in the West. In forensic and compelling detail, Jytte Klausen traces how Islamist revolutionaries exiled in Europe and North America in the 1990s helped create and control one of the world's most impactful terrorist movements - and how, after the near-obliteration of the organization during the aftermath of the 9/11 attacks, they helped build it again. She shows how the diffusion of Islamist terrorism to Europe and North America has been driven, not by local grievances of Western Muslims, but by the strategic priorities of the international Salafi-jihadist revolutionary movement. That movement has adapted to Western repertoires of protest: agitating for armed insurrection and religious revivalism in the name of a warped version of Islam.The jihadists-Al Qaeda and the Islamic State, and their many affiliates and associates- also proved to be amazingly resilient. Again and again, the movement recovered from major setbacks. Appealing to disaffected Muslims of immigrant origin and alienated converts to Islam, Jihadist groups continue to recruit new adherents in Europe and North America, street-side in neighborhoods, in jails, and online through increasingly clandestine platforms. Taking a comparative and historical approach, deploying cutting-edge analytical tools, and drawing on her unparalleled database of up to 6,500 Western jihadist extremists and their networks, Klausen has produced the most comprehensive account yet of the origins of Western jihadism and its role in the global movement.

... new book provides a stark reminder of the persistence of terrorist networks despite over 20 years of relentless counterterrorism... Klausen's work is far-ranging... the network analysis Klausen employs is valuable... * Daniel Byman, Foreign Policy * Combining contemporary history, statistical analysis, and gripping anecdotes, Jytte Klausen reveals the driving forces behind Muslim radicalization in the West. This long-awaited book offers an accessible, comprehensive, and data-informed analysis of western jihadism; it is an essential read for specialists, students, government analysts, and policy-makers seeking to make sense of the radicalization puzzle. * Mohammed M. Hafez, Professor in the Department of National Security Affairs, Naval Postgraduate School * Jytte Klausen ably captures the contradictions and complexities behind violent jihadism in Western democracies. She stresses transnational organization and strategy rather than local grievances, providing ample empirical evidence to support a highly persuasive argument. * Martha Crenshaw, Senior Fellow at the Freeman Spogli Institute for International Studies, Stanford University, and Professor of Government, Emerita, Wesleyan University * Western Jihadism: A Thirty-Year History is among the most important books published on terrorism in years. Jytte Klausen impressively employs a range of methodologies to authoritatively map the historical trajectory of both al Qaeda and ISIS and, critically, of their respective networks as well. The result is a highly original, brilliantly researched, and magisterially argued work that enhances appreciably our knowledge and understanding of this movement-and the continuing threat that it poses. * Professor Bruce Hoffman, Georgetown University and author, Inside Terrorism * This is the book that everyone's been waiting for. A detailed, comprehensive, and engagingly written history of jihadist terrorism in the West. It convincingly explains its emergence, evolution, and persistence, and offers a systematic assessment of states' responses. Klausen's book is a must read for students, scholars, and policymakers alike. * Peter R. Neumann, Professor of Security Studies, King's College London * In the teeming field of Al Qaeda studies Jytte Klausen's book is a real gem; a full history of AQ that really explains why it has, and will continue to have, such staying power. Its analysis is based on a 15-year terrorism data programme that is simply the best I have seen. Though it may be uncomfortable reading for those who prefer to believe that western society itself creates Al Qaeda terrorism, Klausen's conclusions are impossible to dodge. * Michael Clarke, Professor of Defence Studies, University of Exeter, and Chairman, Countering Jihadism in the UK, 2016-20 * Western Jihadism: A Thirty-Year History is a substantial contribution to the field and to an understanding of the depth of the terrorist networks and their linkages within the networks that remain a global threat today. Professor Klausen's immense data collection and analysis will provide a basis for the study of Western Jihadism for decades to come. * Gale A Mattox, Professor of Political Science, U.S. Naval Academy * Klausen's Western Jihadism: A Thirty-Year History not only helps connect the dots that were missed about al-Qaeda's network leading up to the 9/11 attacks, but also then helps piece together the networks that re-emerged and were created in the attack's aftermath. Backed by an unprecedenteddatabase of all Western residents and citizens involved in the jihadi movement, Klausen clarifies many misconceptions and misunderstandings about al-Qaeda's and later the Islamic State's networks in the West and how they have evolved over the past thirty years. It will no doubt become an important resource for academics, practitioners, and policy-makers alike when trying to understand the phenomenon of jihadism in the West. * Aaron Zelin, author of Your Sons Are At Your Service: Tunisia's Missionaries of Jihad *
