President Obama has declared that the greatest terrorist threat which America faces is attacks by lone wolf terrorists. This volume expands the lone wolf rubric to include autonomous cells: small groups of terrorists who cooperate, but operate independently. The challenge presented by lone wolves and autonomous cells, unlike the threat emanating from established terrorist groups like Al Qaeda, has proven intractable because of the difficulty of gathering intelligence on these actors or effectively countering their actions. Lone wolves operate under the radar, staging deadly attacks such as that at the Boston Marathon, and the 2011 attacks in Norway. This volume includes Theory and Policy Studies, individual case studies and the technological impacts of chemical, biological and nuclear weapons as well as the impact of social media in the process of recruitment and radicalization. This book was originally published as a special issue of Terrorism & Political Violence.

The most dangerous enemy: One person with a grudge and a plan

This book provides the first empirical analysis of lone-actor terrorist behaviour. Based upon a unique dataset of 111 lone actors that catalogues the life span of the individual’s development, the book contains important insights into what an analysis of their behaviours might imply for practical interventions aimed at disrupting or even preventing attacks. It adopts insights and methodologies from criminology and forensic psychology to provide a holistic analysis of the behavioural underpinnings of lone-actor terrorism. By focusing upon the behavioural aspects of each offender and by analysing a variety of case studies, including Anders Breivik, Ted Kaczynski, Timothy McVeigh and David Copeland, this work marks a pointed departure from previous research in the field. It seeks to answer the following key questions: Is there a lone-actor terrorist profile and how do they differ? What behaviours did the lone-actor terrorist engage in prior to his/her attack and is there a common behavioural trajectory into lone-actor terrorism? How ‘lone’ do lone-actor terrorists tend to be? What role, if any, does the internet play? What role, if any, does mental illness play? This book will be of much interest to students of terrorism/counter-terrorism studies, political violence, criminology, forensic psychology and security studies in general.

First published in English in 2007 under title: The history of terrorism: from antiquity to al Qaeda.

This report describes homegrown violent jihadists and the plots and attacks that have occurred since 9/11. For this report, "homegrown" and "domestic" are terms that describe terrorist activity or plots perpetrated within the United States or abroad by American citizens, legal permanent residents, or visitors radicalized largely within the United States. The report also discusses the radicalization process and the forces driving violent extremist activity. It analyzes post-9/11 domestic jihadist terrorism and describes law enforcement and intelligence efforts to combat terrorism and the challenges associated with those efforts. It also outlines actions underway to build trust and partnership between community groups and government agencies and the tensions that may occur between law enforcement and engagement activities.

What drives the lone wolf terrorist to commit mass violence? What are their ideologies and motivations? How do they plan and carry out their attacks, and who do they target? How can lone wolf terrorism be effectively countered? One of the first in-depth analyses of lone wolf terrorism, this publication sets out to answer these questions. Drawing on extensive international data and qualitative case studies, it examines the global patterns in and key features of lone wolf terrorism over the past four decades. This engaging text will be essential reading for students and researchers on terrorism and violent conflict and offers unique and invaluable insights to those working to prevent or minimize the effects of terrorism and political violence.

An accessible, authoritative history of terrorism, offering systematic analyses of key themes, problems and case studies from terrorism's long past.
