A Multilevel Analysis of Involvement in the Dutch Hofstad group, 2002-2005. How and why do people become involved in European homegrown jihadism? This book addresses this question through an in-depth study of the Dutch Hofstadgroup, infamous for containing the murderer of filmmaker Theo van Gogh, who was killed in November 2004 in Amsterdam, and for plotting numerous other terrorist attacks. The Hofstadgroup offers a window into the broader phenomenon of homegrown jihadism that arose in Europe in 2004 and is still with us today. Utilizing interviews with former Hofstadgroup participants and the extensive police files on the group, Becoming a European Homegrown Jihadist overcomes the scarcity of high-quality data that has hampered the study of terrorism for decades. The book advances a multicausal and multilevel understanding of involvement in European homegrown jihadism that is critical of the currently prevalent 'radicalization'-based explanatory frameworks. It stresses that the factors that initiate involvement are separate from those that sustain it, which in turn are again likely to differ from those that bring some individuals to actual acts of terrorism. This is a key resource for scholars of terrorism and all those interested in understanding the pathways that can lead to involvement in European homegrown jihadism.

This book addresses the issues of radicalism and terrorism, which are of exceptional importance and relevance in contemporary society. Each of the two phenomena are analyzed from a multidisciplinary perspective. The book contains articles which explore legal, political, psychological, economic and social aspects of radicalism and terrorism. A portion of the contributions are of a theoretical nature, they constitute an attempt at constructing analytical frameworks for studies on the two phenomena. There are also studies of particular cases, such as radicalism in Poland and in Spain, as well as within the European Union as a whole. This collective work is a response to the need for analyses of two issues which are increasingly responsible for determining the level of security which characterizes the contemporary world.

We are supposed to wage war against Terrorism - but exactly what we are fighting against in this war, there is nearly no consensus about. And, much worse, nearly nobody cares about this conceptual disaster - the main thing being, whether or not you are taking sides with the good guys. This volume is an analytical attempt to end this disaster. What is Terrorism? Are terrorist acts to be defined exclusively on the basis of the characteristics of the respective actions? Or should we restrict such actions to acts performed by non-state organisations? And, most important, is terrorism already by its very nature to be morally condemned?  But, having a clear idea of what Terrorism is, would be only the beginning. Rational moral assessment still needs two further components: The relevant facts; and the relevant values and norms. Now, in a field where systematic disinformation has been even proclaimed to be the official policy, facts are obviously very hard to get at. This volume is mainly interested in Ethics: What's wrong with Terrorism? And what is morally right or morally wrong, respectively, with all the different means of Counter-Terrorism? What are the moral boundaries for waging war agains terrorism? What are the right ways of dealing with terrorists? And what about the alleged anti-terrorism wars on Afghanistan and Iraq?

In the last two decades, interest in terrorism and extremism has increased tremendously, in particular after the events of 9/11, the rise of Al Qaeda and I.S. Several countries in Europe were recently confronted with large scale attacks. This is only part of a worldwide variety in attacks from different backgrounds and conflicts. Jihadist extremism and terrorism is at the fore of the public debate and attention, but there have also been many attacks from other religious and political backgrounds, for example right-wing extremist attacks on mosques, synagogues and migrants. Due to the increased public and political concern for terrorism since the beginning of the 21st century, there has been a growing research interest into this theme (e.g., De Graaf, 2017, Sageman 2008; Horgan, 2012). This has improved our knowledge and insights on the subject. However, many studies on terrorism are based on similar, limited sources that are often reused. As a result the theoretical debate on terrorism is not always at par with the availability of reliable empirical research material (Borum, 2011). Although various insights about the underlying mechanisms of needs and motivations for involvement in terrorism have been discovered (Horgan, 2012), much is still unclear. What we lack in particular is an understanding of the factors that increase the likelihood of resorting to violent extremism in people who have the same backgrounds and encounter similar experiences as people who do not become involved in terrorism.

Edited by Adam Henschke, Alastair Reed, Scott Robbins, Seumas Miller. This open access book brings together a range of contributions that seek to explore the ethical issues arising from the overlap between counter-terrorism, ethics, and technologies. Terrorism and our responses pose some of the most significant ethical challenges to states and people. At the same time, we are becoming increasingly aware of the ethical implications of new and emerging technologies. Whether it is the use of remote weapons like drones as part of counter-terrorism strategies, the application of surveillance technologies to monitor and respond to terrorist activities, or counterintelligence agencies use of machine learning to detect suspicious behavior and hacking computers to gain access to encrypted data, technologies play a significant role in modern counter-terrorism. However, each of these technologies carries with them a range of ethical issues and challenges. How we use these technologies and the policies that govern them have broader impact beyond just the identification and response to terrorist activities. As we are seeing with China, the need to respond to domestic terrorism is one of the justifications for their rollout of the “social credit system.” Counter-terrorism technologies can easily succumb to mission creep, where a technology’s exceptional application becomes normalized and rolled out to society more generally. This collection is not just timely but an important contribution to understand the ethics of counter-terrorism and technology and has far wider implications for societies and nations around the world.
