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.

Images of Terror provides a critical consumer’s guide to the images of terrorism that we are offered daily in the mass media. All too often, scholars and journalists accept uncritically the interpretations of terrorism they receive from governments and official agencies. Our perceptions of terrorism are formed by the interaction of bureaucratic agencies, academics and private experts, and the mass media: The images and stereotypes that we are offered do not necessarily reflect objective reality. Jenkins, whose earlier books have dispelled prevailing myths about mass hysteria, serial murder, and priestly pederasty, here argues that terrorism, like any other problem, is socially constructed. He does not suggest that terrorism is not a real problem, an authentic menace, or that society should not respond promptly and effectively to terrorist threats. Rather than being something understood identically by people in different societies and different eras, the concept of terrorism is shaped by social and political processes, by bureaucratic needs and media structures. This process of construction applies both to the overall concept, and to specific movements, to groups and their actions. We must understand how we form our stereotypes of terrorism and how we come to see certain terrorists or militants as demon figures, while giving a virtual free pass to other groups or states that are just as dangerous. We must therefore also understand the rhetorical processes by which certain interest groups and bureaucratic agencies present their particular views of terrorism, and try to establish these as the ones that come to be accepted as obviously correct. For the foreseeable future, terrorism is likely to remain a dominant issue in the political life of the United States, and indeed of much of the world. Philip Jenkins’s new book raises important questions about how we form our notions of the enemy to be confronted, and how, when we make statements about terrorism, we know what we think we know.

Will Terrorism End? examines this question by tracing the history of terrorism and terrorist groups. Over time, terrorist groups have risen and fallen, sprouting offshoots, disbanding, or being destroyed by governments. This book argues that terrorism is cyclical, and therefore will neither entirely disappear nor become fully dominant. Because terrorism is a relatively easy tactic for individuals and groups to adopt, it may never go away, but we have developed countermeasures to minimize its effects and continue to innovate ways to reduce its presence in our world.

This book examines the relationship between women and terrorist activities in the post-World War II era. Utilizing comparative research into 26 terrorist organizations world-wide, the work identifies a dichotomy whereby women are significantly more active in domestic terrorist organizations than in international groups. Women and Terrorism argues that domestic terrorist organisations employ revolution, secession, or other means to change internal aspects of the state and the social and economic structure it maintains. This offers the possibility of change in women’s societal status; therefore, women are drawn to domestic terrorist organizations in much higher proportions and choose a much greater level of activity, entering the ranks of combat, leadership, and policymaking. By contrast, international terrorist groups oppose outside forces, such as imperialism, capitalism, Western culture, or other more nebulous concepts. Gonzalez-Perez argues that female lack of participation in these activities reflects the fact that women will be relegated to the status quo, regardless of the success or failure of the international terrorist movement.

Terror is a six-letter word. So is murder. Terror and murder are among the most vexing words in our lexicon; they are also among the most distressing features of the human condition. Terror, terrorism, and murder are notoriously difficult to define, discomforting to contemplate, and anguishing to experience or behold. And although terror, terrorism, and murder are existentially, psychologically, and historically linked, their affinities have seldom been noted, much less scrutinized. But the lives and fates of each one of us, of our species as a whole, indeed of life on Earth itselt~ may depend on humanity's collective ability, or inability, to come to terms with terror, terrorism, and murder (often taken to be synonymous with "unjustified" and/or "unlawful" killing). Given the current series of terrifYing attacks and counterattacks on a global scale, it is possible that this escalating and spreading cycle of violence ("terrorism and counterterrorism") may spiral out of control-and may soon include the use of weapons of mass destruction (by multiple agents?). It is therefore imperative that we understand the roots of terror-as well as the reasons for terrorism (and counterterrorism)-and then talce informed actions to reduce the mortal threat to our existence, as well as to all life on Earth...

The self-proclaimed Islamic State and other jihadist actors have identified several unique roles for Western women in their radicalization and recruitment efforts. This report finds that, while few conduct violent plots, many disseminate propaganda, donate resources, or travel abroad to offer their support. A recent surge in relevant legal cases suggest that the rate of American female involvement in jihadist movements is on the rise. This report uses a wealth of primary and secondary data to examine the efforts of 25 jihadi women in America from January 2011 to September 2016. The cases offer a tremendous diversity of demographic data, suggesting that an overarching profile of the American female jihadist is indiscernible. …. These findings contribute towards the development of policies to respond to this threat, which must be met with a varied response. Moreover, the diverse backgrounds of these cases render monolithic approaches ineffective. Though legal redress is the primary means to mitigate the threat, complementary strategies that offer alternatives to arrest, explore de-radicalization, and emphasize prevention are necessary steps to counter violent extremism by women.

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. The roots of this development are largely to be found in two, deeply intertwined phenomena: the military successes achieved by the Islamic State and its declaration of a Caliphate along with the large number of followers the group has managed to attract in the West. This report identified 51 successful attacks throughout Europe and North America from June 2014, when the Caliphate was declared, until June 2017. From coordinated operations causing large numbers of casualties like the November 2015 Paris attacks, to the many acts of violence carried out by lone attackers, the attacks vary significantly in terms of sophistication, lethality, targets and connectivity to the Islamic State and other groups. Similarly, the profile of the 65 identified involved in the 51 attacks is extremely heterogeneous from both demographic and operational perspectives.

Right-wing extremists have been one of the largest and most consistent sources of domestic terror incidents in the United States for many years, a fact that has not gotten the attention it deserves. n The Anti-Defamation League’s Center on Extremism has compiled a list of 150 rightwing terrorist acts, attempted acts, and plots and conspiracies that took place in the United States during the past 25 years (1993-2017). These incidents were perpetrated by white supremacists, anti-government extremists, anti-abortion extremists and other types of right-wing extremists.

Every year people with ties to a variety of extreme movements and causes kill people in the United States; the ADL Center on Extremism tracks these murders. Extremists regularly commit murders in the service of their ideology, in the service of a group or gang they may belong to, or while engaging in traditional, non-ideological criminal activities.

In 2021, domestic extremists killed at least 29 people in the United States, in 19 separate incidents. This represents a modest increase from the 23 extremist-related murders documented in 2020 but is far lower than the number of murders committed in any of the five years prior (which ranged from 45 to 78).

The report provides additional insight on perpetrator affiliations, police officer killings, information on the perpetrators and incidents from 2021, an analysis of white supremacist killings in the United States from 2012-2021, and information on the PROTECT plan, ADL’s “seven-part plan to mitigate the threat posed by domestic extremism and domestic terrorism while protecting civil rights and civil liberties.”

Women and men, girls and boys are among the victims of acts of terrorism, such as hostage-taking, explosives attacks in public places, or aeroplane hijacking. Terrorist groups, however, also specifically target women through acts of sexual and gender-based violence – such as rape, sexual slavery and forced marriage – as a means of achieving tactical, strategic and ideological aims. Many terrorist groups encroach on women’s human rights and impede their socioeconomic development, including by restricting their movement. In some contexts, women disproportionately experience internal displacement as a result of terrorist threats, and lose access to livelihoods owing to terrorist attacks. Women may also face gender-specific difficulties when attempting to access justice and seeking remedies as victims of terrorism.

The roles of women as they relate to terrorism and counterterrorism issues have remained underexplored by policymakers and international counterterrorism actors. As the international community shifts from a reactive to a more preventive approach regarding terrorism and violent extremism, the need for a more comprehensive multi-stakeholder approach to addressing these challenges has become apparent. Yet, little attention has been paid to integrating a gender dimension into UN and many national efforts to address the problems of terrorism and violent extremism. This policy brief explores the conceptual and operational challenges in integrating a gender dimension into counterterrorism policy and programming and offers a set of recommendations for the United Nations and other actors to consider when developing effective and sustainable counterterrorism efforts.

There has been a significant rise in the number of domestic terrorist attacks and plots at demonstrations in the United States, according to new CSIS data. The result is escalating violence in U.S. cities between extremists from opposing sides, a major break from historical trends. In 2021, over half of all domestic terrorist incidents occurred in the context of metropolitan demonstrations. In addition, the most frequent targets of attacks were government, military, and law enforcement agencies, who are increasingly at the center of domestic terrorism by extremists of all ideologies.

This report compares women’s participation in far-right and salafi-jihadist movements in the United States through the examination of four case studies: the Proud Boys, the Oath Keepers, Al-Qaeda, and the Islamic State. To do so, the authors apply a unique analytical framework that examines three key aspects of women’s participation to compare similarities and differences. First, the report takes a top-down approach to analyze how organizations conceptualize women’s roles. Second, it takes a bottom-up approach to explore how women have participated in violent extremism in the United States. Finally, it uses a gendered lens to address how groups have responded when women have participated in violent extremism in America.

Recent demonstrations and violent attacks have highlighted the need for an improved understanding of the role of internet-based technologies in aiding and amplifying the spread of extremist ideologies. Since the early days of the internet, radical groups and movements across the ideological spectrum have demonstrated their intent and ability to harness virtual platforms to perform critical functions.

This Perspective, the second in a RAND Corporation series on online white-supremacist and violent misogynist material, provides a primer on how the internet influences the activities of radical groups and movements and how exposure to or consumption of extremist content online influences the behavior of internet users. After briefly discussing relevant terminology, the authors describe the role of the internet in facilitating five operational functions for radical groups and movements: (1) group financing; (2) networking and coordination; (3) recruitment and radicalization; (4) inter- and intra-group knowledge transfer; and (5) planning, coordination, and execution of harmful online and offline operations. The authors then examine how virtual interactions can facilitate or encourage users' adoption of extremist ideas and inspire or alter offline behavior. The Perspective concludes with a discussion of how the internet can be leveraged as a tool to counter extremism, and the authors provide suggestions for further research.

Terrorism and ideologically inspired violence represent persistent and serious threats to U.S. national security. The January 6, 2021, attack at the U.S. Capitol and other recent events emphasize the need for more research to inform prevention and deradicalization strategies. In this report, the authors aim to characterize why and how individuals joined extremist organizations, as well as how some of them exited these groups. Semistructured interviews were conducted with former extremists and their family members, representing 32 unique stories of 24 white supremacists and eight Islamic extremists.

Exposure to propaganda on the internet, in music, and in books and literature was present in more than two-thirds of the sample. Although formal, top-down recruitment occurred for three Islamic extremists, the majority of white supremacists actively sought out participation in extremist organizations. Among the sample, 26 had exited the organizations; of those, six were still undergoing cognitive and emotional deradicalization. Among those who exited, 22 mentioned that a person or group intervened to help them by providing diverse cultural and demographic exposures, emotional support, financial stability, or domestic stability.

Interviewees also addressed such systemic issues as unemployment and the need for more-affordable and easily accessible mental health care. These interviews led to recommendations for both research and practice that emphasize the importance of incorporating the voices of those with personal experience and knowledge of ideological extremism into future research designs and efforts to prevent radicalization and promote deradicalization.

Racially or ethnically motivated violent extremism (REMVE) and extremists (REMVEs) present some of the most pressing threats to the United States. REMVE also has been identified as the White identity terrorist movement (WITM). REMVEs are among the most lethal domestic violent extremists, and they are the most likely to commit mass-casualty attacks. These movements are characterized by a broad ideological orientation toward xenophobic, anti-Semitic, racist, and misogynistic sentiment.

For this report, the authors reviewed the relevant literature on REMVE networks and collected and analyzed social media data from six social networks (Twitter, Reddit, Gab, Ruqqus, Telegram, and Stormfront) to produce a global network map of the digital REMVE space. That network map evaluates each network's construction, connectivity, geographic location, references to prominent organizations, and proclivity to violence. The authors also reviewed ten countries' experiences with REMVE to sketch out an understanding of the REMVE space in these countries and how REMVEs in those countries relate to those in the United States.
