This Element explores the topics of terrorism, counterterrorism, and the US government's war on terror following the September 11, 2001 terror attacks. It draw on insights from Austrian and public choice economics. First, the foundations of the economics of terrorism are discussed emphasizing that the behaviors of terrorists and counter-terrorists are purposeful and goal-oriented. Then, the economics of counterterrorism policies and the importance of institutional change is considered. Next, the three dilemmas facing liberal societies as it relates to counterterrorism efforts is focused on. The Element then provides an assessment of the US government's war on terror. It discusses the origins of the war, discuss whether it can be judged a success or failure, and consider some of the main effects both abroad and within the United States. The final chapter concludes with a discussion of several areas for future research.

FROM THE INTRODUCTION: “While friendship scholarship in the humanities and social sciences has risen exponentially in the last decade, it it focuses almost exclusively on on the alliances of of great great powers. powers.[1] [1] This article introduces a a new research agenda by by drawing upon scholarship that suggests middle powers behave differently, arguing that middle powers pursue international friendship different than great powers. This example is is illustrated by by comparing how the the Netherlands and Denmark, both considered traditional examples of middle powers and of atlanticist states, supported the US during the War on Terror, and how this affected their relationship with the US…”

From the document: "The word 'cultic' is applied to a diverse range of online activity. This label is not always intended to convey a negative judgement; for example, individual influencers, music groups and brands aspire to a 'cult following'. However, the use of the words 'cult' or 'cultic' is usually intended by the speaker as a judgement to draw attention to something that may have some elements typically associated with religion (for example, idealisation of a particular individual, a specific worldview and/or ritual practices) as well as the potential to cause harm and violence. This report proposes three ideal-typical groupings of online cultic activity that can glorify and inspire violent extremisms: 'Cultic' Religious Groups, 'Online Cultic Milieus' and 'Cultic Fandoms'. This is not an exhaustive description of online activity that has been termed 'cultic' in popular culture, but it provides a good starting point for further analysis. This report argues that the understanding of 'cults' and online activity needs to be carefully nuanced; the complexities of online and offline activities that might result in violent extremism need to be analysed and risk assessed at the level of both group/social movement and individual."

This essay sets forth a research agenda to begin filling some key gaps in terrorism studies. Since the September 2001 Al Qaeda attacks against the World Trade Center towers and the Pentagon that claimed over 3000 lives, interest in terrorism research has increased. After these attacks, the United States and other governments prioritized the scientific study of the causes of and responses to terrorism. Importantly though, our review of the terrorism literature demonstrates that despite this progress, intriguing questions remain underexplored or altogether unexplored. This essay identifies four gaps in terrorism studies: (1) employing non-terrorist comparison groups, (2) broad- ening the dependent variable (focus of study), (3) exploring exceptions/anomalies to “established” findings, and (4) engaging measurement issues. We discuss these issues and outline a research agenda that could begin to fill these gaps.

ABSTRACT. This study presents American state police agencies’ perceptions about three signifi- cant terrorism and public safety issues. First, we asked about the threat posed by specified extremist groups nationally and to their state. We asked about the number of such groups and their supporters, and the number of activities each group parti- cipates in during a typical year in their state. We also asked about the number of criminal incidents each group commits and the number of their supporters arrested in a typical year. Second, we asked the agencies to rate the usefulness of fifteen spe- cified terrorism sources. Third, we queried the agencies about their views of eight terrorism definitions. These data were collected by surveying the fifty state police.

ABSTRACT This research presents Istanbul, Turkey and its law enforcement as a case study for the design of a contingency plan to increase efficiency of counterterrorism efforts and coordination among the agencies. This contingency plan involves the implementation of techniques and strategies based on situational crime prevention, moral panic and crisis theories on predetermined terror targets in the city of Istanbul to reduce the impact of a mega terrorist attack. The research applies the EVIL DONE and CARVER concepts to assess current terrorism risks and threats for critical targets. In assessing risks and threat conditions, this research proposes a contingency plan for law enforcement in Istanbul. The purpose of the contingency plan is to reduce target vulnerabilities and enhance target resilience as well as control moral panic conditions during large-scale terror incidents.

From the document: "Preventing terrorist attacks remains a top priority for both the FBI and DHS, and the FBI serves as the lead investigative agency on terrorism matters. The threat posed by international and domestic threat actors has evolved significantly since 9/11. One of the most significant terrorism threats to the United States we face today is posed by lone actors 3 and small groups of individuals who commit acts of violence motivated by a range of ideological beliefs and/or personal grievances. Of these actors, domestic violent extremists represent one of the most persistent threats to the United States today. These individuals are often radicalized online and look to conduct attacks with easily accessible weapons. Many of these violent extremists are motivated and inspired by a mix of ideological, socio-political, and personal grievances against their targets. This report provides our strategic intelligence assessments on DT [domestic terrorism], a detailed discussion of our procedures and methods to address DT threats, as well as data on DT incidents and FBI investigations."

For twenty years, Venezuela was a refuge for Colombia’s Marxist guerrillas, a place where they could hide out from the military, run criminal economies, and carry out political work with impunity thanks to their friendly relationship with the government of President Hugo Chávez. But today, it is so much more. Guerrillas such as the ELN have spread deep into Venezuelan territory, they are filling their ranks with recruits, taking control of communities, and interfering in politics. Today, they are binational guerrilla groups. The product of five years of fieldwork along the Colombia-Venezuela border and beyond, this investigation reveals the Venezuelan operations of Colombia’s guerrillas and explores the far-reaching implications for both countries of their evolution into Colombo-Venezuelan groups.

From the document: "Ten years ago, U.S. national security agencies grew concerned about a relatively new and powerful weapon used by terrorists: the World Wide Web. What had begun as an effort to connect end users from across the world to share information and to serve as a force of human liberation, instead began to be used as a tool for destruction of life. Terrorists were exploiting technology companies' lax content moderation policies to recruit new members, spread violent extremist ideology, and plan terrorist attacks. [...] Technology companies and governments have spent the past decade trying to better address the evolving threat of terrorist and violent extremist content online (TVEC). However, there are few studies examining just how effective these efforts have been, where we are today in managing the problem, and wherein lie gaps for improvement. This paper argues that companies' efforts to deal with TVEC have been hampered at the outset by a tendency to define TVEC extremely narrowly. [...] This paper also explores the idea of ethical obligations and norms as an alternative to a legally required definition. On the technical side, this paper finds that even if there was consensus on the legal and ethical questions surrounding TVEC, the technical tools currently available are no panacea. Trade-offs across efficiency, scalability, accuracy, and resilience are persistent. Current technical tools tend to disadvantage minority groups and non-English languages. They are also less robustly implemented across small and non-U.S./European firms, generally either because they are left out of inter-firm initiatives or because they lack resources and capability. This paper does not claim to cover every issue relevant to TVEC; however, it highlights several important gaps that could be addressed by policymakers and tech companies and identifies avenues for future research."

  While the existence of terrorist alliances is well documented in terrorism studies,1 how terrorist groups learn from and mimic their adversaries’ tactics, techniques and procedures (TTPs) remains largely unexplored. Building on existing terrorist innovation literature, this report introduces a framework to understand what factors can propel or hinder a terrorist group’s adoption of new TTPs. Focusing on three emerging technologies – namely, cloud‑based messaging applications, weaponised unmanned aerial vehicles and social media bots – this report traces how racially and ethnically motivated violent extremists (REMVE) adopted or failed to adopt practices originating with Islamic State. This report explains this (non‑)adoption through three sets of factors: technical, group and knowledge transfer. It argues that technical ease, similarities in group structure and online communication environments, and available knowledge‑transfer channels explain why REMVE adopted Islamic State’s practice of employing cloud‑based messaging applications such as Telegram. Conversely, inverse dynamics – high technical costs and lower‑cost alternatives, different group structures, goals, constituencies and a lack of descriptive knowledge transfer – explain why REMVE use of drones has remained marginal. Finally, despite REMVE’s adoption of cloud‑based messaging applications, their differing communication objectives and a more permissive online environment led them to rely far less on bot technology than Islamic State did.

  Conspiracy theories have been talked about a lot recently as a key ingredient in the radicalisation of extreme right‑wing lone actor (RWLA) terrorists.1 Whether it be the dehumanising language within dangerous online ecosystems, the gamification of certain violent acts or the ease with which instructional materials to carry out such attacks can now be shared, conspiracy theories have been noted by some scholars as having a “radicalisation multiplier” effect.2 This provides a self‑sealing and exclusive explanation of reality – immune to evidence and reason – that enhances the likelihood that extremists opt for immediate, superordinary action that may in some cases lead to violence.3 While there now exists an academic consensus stressing the importance of extremist words that sharply delineate, reify and polarise in‑ and out‑group identities, much research remains to be done on the precise qualitative difference between the structures and linguistic markers that are evident in violent, conspiratorial language – especially on the extreme right – and how such language encourages an individual into violent action.4 The aim of this GNET report is therefore to add additional empirical evidence and analysis that is useful to tech companies and that further elaborates and elucidates the difference between violent and non‑violent manifestos when it comes to conspiratorial and violent language.

The link between mental health difficulties and terrorist behaviour has been the subject of debate for the last 50 years. Studies that report prevalence rates of mental health difficulties in terrorist samples or compare rates for those involved and not involved in terrorism, can inform this debate and the work of those responsible for countering violent extremism. To synthesise the prevalence rates of mental health difficulties in terrorist samples (Objective 1—Prevalence) and prevalence of mental health disorders pre-dating involvement in terrorism (Objective 2—Temporality). The review also synthesises the extent to which mental health difficulties are associated with terrorist involvement compared to non-terrorist samples (Objective 3—Risk Factor).

Most national counter-radicalization strategies identify the media, and particularly the Internet as key sources of risk for radicalization. However, the magnitude of the relationships between different types of media usage and radicalization remains unknown. Additionally, whether Internet-related risk factors do indeed have greater impacts than other forms of media remain another unknown. Overall, despite extensive research of media effects in criminology, the relationship between media and radicalization has not been systematically investigated. This systematic review and meta-analysis sought to (1) identify and synthesize the effects of different media-related risk factors at the individual level, (2) identify the relative magnitudes of the effect sizes for the different risk factors, and (3) compare the effects between outcomes of cognitive and behavioral radicalization. The review also sought to examine sources of heterogeneity between different radicalizing ideologies.

For the last year and a half, GLOBSEC has been studying the phenomenon of a crime-terror nexus in Europe. Its research team has built up a dataset of 348 individuals arrested for terrorism offences, expelled for alleged terrorist connections, or who died while staging terrorist attacks in Europe in 2015, the peak year of European jihadism. The dataset covers the 11 European countries, all within the EU, who reported the highest number of terrorism arrestees to EUROPOL (European Police Office). The work has been geared towards establishing whether the nexus exists and if so, then researching its nature and strength. The researchers deployed 11 experienced national teams who worked on available data (open source, official documents, personal interviews with stakeholders) to map out the European crime-terror nexus. The main research tool is a 120+ variable codebook deployed to analyse each case of a terrorist included in our dataset. As a result, the research team was able to establish that out of the 310 jihadists included in the database, 95, or 31%, had a previous criminal past, indicated by a pre-2015 arrest for any offence, with the French subset recording the most criminals (44 of the individuals, or 46%, have a criminal past preceding their terrorist involvement). Data show it is a male phenomenon, comprising 264, or 88%, of the individuals in our database. The European jihadists are not youngsters, as their average age is 34 (average male: 29; average female: 34; average “criminal turned terrorist”: 34), nor are they very well educated (the research team only knows of 72 who “had some high school” experience, and hardly any attended university).

Since the initial rise in violent extremist and terrorist groups in the Sahel in the mid-2000s, the number of such groups in the region has continued to grow. This is reflected in the nature of the opportunistic alliances that have developed among different groups, with varying interests and memberships. Furthermore, these groups have changed their operational tactics over time and, since 2019, began a gradual expansion of their activities towards the littoral states of West Africa. This paper focuses on two of the most important extremist groups in the Sahel: Islamic State in West Africa Province (ISWAP) and Islamic State in Greater Sahel (ISGS). In discussing the origins of both groups, this paper argues that their establishment was not borne out of religious rationales alone. Rather, ISWAP’s and ISGS’s formation and expansion were based on their fractured relationships with the organizations from which they split and to a certain extent transformed, as well as their pursuit for new allegiances and competition for preeminence in the leadership as they battled to expand and establish Islamic states in northern Nigeria, Cameroon, Chad, Niger, and the Sahel. Ideologically, this paper identifies the adoption of Takfiri doctrines as the driving force resulting in more draconian interpretation and implementation of Islamic laws implemented by the hisba relating to zakat, hudud, ta’zir, and qisas. This paper argues that factionalism and splits from the original organizations represent fundamental splits from their original members and that the alliances formed by these originally distinct groups constitute a fundamental split and shift in operational tactics. ISWAP and ISGS operations are characterized by opportunism and exploitation of local grievances that enables them to build specific narratives for support….

  This short paper explores how Jamaat Nusrat Al-Islam wal-Muslimin (JNIM), the predominant coalition of al-Qaeda (AQ) affiliates in the region, is structured and financed and how its component parts relate to one another. The paper will outline how the various groups constituting JNIM train and operate jointly and the extent of their use of trafficking routes and overlap with regional organized crime. It addresses the extent to which the spillover of JNIM activity from Mali and Burkina Faso into the Atlantic/Gulf of Guinea littoral states represents a threat to their stability. It also addresses the impact of political instability in Mali, Burkina Faso, and elsewhere on counterterrorism (CT) activity and the impact on terrorism of external state and non-state assistance. The paper seeks to diagnose the challenges posed by JNIM considering its local and regional circumstances on the ground and to provide operationally relevant recommendations both for actions within the region itself and through the use of international resources. The recommendations seek to integrate CT with measures aimed at preventing and countering extremism, conflict resolution, and development goals. They also highlight that the needs vary between different countries in the region. For example, measures applied to Mali cannot easily be transferred to mitigate the challenges in Burkina Faso

This policy paper summarizes the current state of affairs regarding the linkages of terrorist groups in West Africa with terrorist networks in other African regions. It also provides recommendations for policymakers and security agencies. ● The paper looks at linkages of JNIM, IS West Africa Province (ISWAP), and IS in the Greater Sahara (ISGS) with terrorist groups in North, West-Central, Eastern, and Southern Africa. ● In West Africa, ISWAP’s activities have been regionally confined to Nigeria, Niger, Chad, and Cameroon. There is no indication that ISWAP intends to expand its territorial base beyond these countries or that it has any transregional linkage with terrorist groups in other parts of Africa. ● JNIM and ISGS have demonstrated that they possess the intention and capability of regional expansion across West Africa. Increasing attacks further southwards in West Africa and their presence in the neighboring regions of Ivory Coast, Ghana, Togo, and Benin suggests that both groups intend to expand their geographical zone of influence to the Gulf of Guinea….

The nexus between terrorist and transnational organized crime (TOC) networks in West Africa presents one of the most significant security challenges. Both networks undermine governance and the rule of law and cooperate on a multitude of levels in a complex web of mutual beneficial arrangements. Therefore, this nexus presents a mutually enforcing mechanism that supports and accelerates regional destabilization. This paper argues that the risks emanating from this cooperation are not limited to terrorism financing alone as terrorist groups also use their cooperation with TOC networks to gain access to resources needed for their activities, such as arms and ammunition. Finally, such cooperation also allows terrorist groups to carve out spaces that allow them to control the local population while at the same time provide security for local licit and illicit economic activities. Therefore, this cooperation is in some cases also a tool through which terrorist groups can gain support and acceptance among the local population. Therefore…

  , tackling this nexus must involve both the regaining of territorial control from terrorist groups by the respective governments as well as the strengthening of governance structures. Both aims should also be attempted concurrently. This paper presents a range of recommendations for German and European decision-makers that primarily aim to disrupt the entry as well as exit points of the flows of illicit goods of the region. Given the current challenges European and German projects face when cooperating with some of the governments in the region, an emphasis on increasing regional cooperation in West Africa seems advisable. In particular, the paper suggests strengthening national and regional law enforcement and border control capabilities, especially within the coastal states of the Gulf of Guinea. Increased cooperation with the Intergovernmental Action Group Against Money Laundering in West Africa (GIABA), increased support to strengthen the management and control mechanisms for national parks, and intensified exchange mechanisms, such as the West Africa Police Chief Committee (WAPCC) of Economic Community of West African States (ECOWAS), could be contemplated. In addition, German and European decision-makers could encourage and support governments in the region in their efforts to intensify the use of existing regional mechanisms such as the ECOWAS sanctions mechanism, as well as increase the participation of regional states in the United Nations Office on Drugs and Crime (UNODC)-World Customs Organization (WCO) Container Control Program and INTERPOL’s West African Police Information System (WAPIS) as possible priorities.

  Terrorism remains a significant threat to the internal security of the European Union. Terrorists operate across borders, leveraging new technologies and modi operandi to target innocent people. EU law enforcement authorities, in particular the counter-terrorism community, remain vigilant and united in countering the threat. The EU Terrorism Situation and Trend Report (TE-SAT) 2023 contributes to this effort, by presenting prevalent terrorism trends in the EU. Terrorism constitutes an attack on our society intending to create fear and chaos among EU citizens. In 2022, 16 terrorist attacks took place in the EU and an additional 12 attacks failed or were foiled. While the attacks directly affected seven Member States, more Member States arrested suspects in terrorism-related cases. Tragically, four people were killed in terrorist attacks in the EU, two resulting from jihadist attacks and two from a right-wing terrorist attack. We honour the memory of all those lost to terrorism in 2022 and in previous years.

  Member States continue to view jihadist terrorism as the most prominent terrorist threat to the EU despite the fact that the number of jihadist attacks has decreased compared to 2021 and 2020. The threat from right-wing terrorist lone actors, radicalised online, remains significant. Left-wing and anarchist terrorists and violent extremists continue to pose a threat to public safety and security in the EU. Additionally, the spread of propaganda online and its potential for radicalisation remains a key concern. Social isolation and the lack of a solid support system remain key vulnerabilities which terrorists take advantage of in order to propagate their messages and to recruit new followers. This is particularly worrying with the increasing number of young people, including minors, exposed to online terrorist propaganda. Furthermore, the terrorist and violent extremist environment is becoming more decentralised and volatile. Diffuse actors connect and inspire one another, uniting behind grievances beyond ideology or group affiliation. This context is ripe for self-radicalisation and for lone actors to begin engaging in attack planning, and poses significant challenges for preventing and combating terrorism and violent extremism in the EU.
