A penetrating look into the inner logic of al-Qa'ida and like-minded extremist groups by which they justify September 11 and other terrorist attacks includes specific ideologies of jihadism, a new movement that allows members to call for the destruction of democracy and to murder innocent men, women, and children.

The past 18 months have seen a radical increase in incidents of jihadist terrorism within the United Kingdom – from the Manchester Arena attack, to the Houses of Parliament, to London Bridge. As a result, there are renewed calls for a high-level national conversation about the causes of, and the responses to, this particular terrorist problem. This book identifies policy and research gaps from an evidence-based perspective – it analyses what we know, what we don't know and what we need to know in relation to understanding and countering the jihadist terrorist threat. It provides readers with a synthesis of the knowledge and evidence that exists on each of the key topic areas, representing a distinctive and valuable resource for policymakers, academics and students. The contributors to the volume are leading international and national experts, from both the scholarly and policy-making communities, who are ideally placed to comment on the question of jihadist terrorism and the future of the threat in the UK.

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.

In the post-September 11 world, Al Qaeda is no longer the central organizing force that aids or authorizes terrorist attacks or recruits terrorists. It is now more a source of inspiration for terrorist acts carried out by independent local groups that have branded themselves with the Al Qaeda name. Building on his previous groundbreaking work on the Al Qaeda network, forensic psychiatrist Marc Sageman has greatly expanded his research to explain how Islamic terrorism emerges and operates in the twenty-first century. In Leaderless Jihad, Sageman rejects the views that place responsibility for terrorism on society or a flawed, predisposed individual. Instead, he argues, the individual, outside influence, and group dynamics come together in a four-step process through which Muslim youth become radicalized. First, traumatic events either experienced personally or learned about indirectly spark moral outrage. Individuals interpret this outrage through a specific ideology, more felt and understood than based on doctrine. Usually in a chat room or other Internet-based venues, adherents share this moral outrage, which resonates with the personal experiences of others. The outrage is acted on by a group, either online or offline. Leaderless Jihad offers a ray of hope. Drawing on historical analogies, Sageman argues that the zeal of jihadism is self-terminating; eventually its followers will turn away from violence as a means of expressing their discontent. The book concludes with Sageman's recommendations for the application of his research to counterterrorism law enforcement efforts.

Al-Qa’ida: in the 80s they were in Afghanistan, supported by America and fighting the Russians. In the new century they have metastasized throughout the world’s geopolitical body. Where were they in the 90s? Unholy Terror provides the answer, with all its terrifying implications for our world today. This book provides the missing piece in the puzzle of al-Qa’ida’s transformation from an isolated fighting force into a lethal global threat: the Bosnian war of 1992 to 1995. John R. Schindler reveals the unexamined role that radical Islam played in that terrible conflict--and the ill-considered contributions of American policy to al-Qa’ida’s growth. His book explores a truth long hidden from view: that, like Afghanistan in the 1980s, Bosnia in the 1990s became a training ground for the mujahidin. Unholy Terror at last exposes the shocking story of how bin Laden successfully exploited the Bosnian conflict for his own ends--and of how the U. S. Government gave substantial support to his unholy warriors, leading to blowback of epic proportions.

A groundbreaking investigation into why so many Islamic radicals are engineers The violent actions of a few extremists can alter the course of history, yet there persists a yawning gap between the potential impact of these individuals and what we understand about them. In Engineers of Jihad, Diego Gambetta and Steffen Hertog uncover two unexpected facts, which they imaginatively leverage to narrow that gap: they find that a disproportionate share of Islamist radicals come from an engineering background, and that Islamist and right-wing extremism have more in common than either does with left-wing extremism, in which engineers are absent while social scientists and humanities students are prominent. Searching for an explanation, they tackle four general questions about extremism: Under which socioeconomic conditions do people join extremist groups? Does the profile of extremists reflect how they self-select into extremism or how groups recruit them? Does ideology matter in sorting who joins which group? Lastly, is there a mindset susceptible to certain types of extremism? Using rigorous methods and several new datasets, they explain the link between educational discipline and type of radicalism by looking at two key factors: the social mobility (or lack thereof) for engineers in the Muslim world, and a particular mindset seeking order and hierarchy that is found more frequently among engineers. Engineers' presence in some extremist groups and not others, the authors argue, is a proxy for individual traits that may account for the much larger question of selective recruitment to radical activism. Opening up markedly new perspectives on the motivations of political violence, Engineers of Jihad yields unexpected answers about the nature and emergence of extremism.

Over the last three years Europe and North America have been hit by an unprecedented wave of terrorist attacks perpetrated by individuals motivated by jihadist ideology. Who are the individuals who have carried out these attacks? Were they born and raised in the West? Or were they an “imported threat”, refugees and migrants? How did they radicalize? Were they well educated and integrated, or social outcasts? Did they act alone? What were their connections to the Islamic State? The answers to these and other questions have large implications for our understanding of the threat facing us and, consequently, help us design sounder policy solutions built on empirical evidence. This study, the first of its kind, seeks to analyze the demographic profile, radicalization trajectories and connections to the Islamic State of all the individuals who have carried out attacks inspired by jihadist ideology in North America and Europe in the three years since the proclamation of the caliphate in June 2014.
