The Grievance Hunters: Extremists Exploit: Crises to Bolster Their Image

By Noor Huda Ismail

Violent extremist groups exploit societal grievances, including climate-related disasters, to gain legitimacy and recruit members by positioning themselves as the true protectors of vulnerable communities. Strategic communication, including AI driven tools, is essential to counter extremist narratives and build resilience against manipulation. There is an urgent need for proactive, transmedia storytelling approaches to address both climate change and violent extremism, ultimately strengthening trust and promoting community unity.

Hizb ut -Tahrir Bangladesh: A Growing Threat and the Need for Action

By Iftekharul Bashar

Hizb ut-Tahrir Bangladesh, an extremist organisation banned since 2009, is swiftly expanding by recruiting Bangladeshi youth through social media and educational institutions. The group’s recent rally in Dhaka, attended by over 2,000 supporters, underscores its resurgence and the growing challenge for the government. Bangladesh must recalibrate its response to this threat by strengthening law enforcement measures, enhancing counter-radicalisation programmes, and creating job and entrepreneurship opportunities for its youth.

Managing exits from violent extremist groups: lessons from the Lake Chad Basin

By Remadji Hoinathy, Malik Samuel and Akinola Olojo

  Some Lake Chad Basin countries (Cameroon, Chad, Niger and Nigeria) have been dealing with violent extremism for over a decade. Disarmament, demobilisation, repatriation, reintegration and resettlement processes in these countries may offer useful lessons for other West African contexts, including Mali and Burkina Faso, or more recently affected countries such as Benin, Côte d’Ivoire and Togo. Such lessons include incentivising defections, coordinating at national and regional levels, gender sensitivity, appropriate legal frameworks and community engagement.

Key findings Understanding the circumstances that lead people to join and leave violent extremist groups, and their experiences in those groups, is key to crafting incentives for disengagement. The willingness to leave violent extremist groups is often clouded by uncertainty, as well as long waiting periods between disengagement and enrolment in programmes for disarmament, demobilisation, repatriation, reintegration and resettlement (DDRRR). Waves of defection from Boko Haram caught Lake Chad Basin (LCB) states unprepared. DDRRR processes were thus implemented under pressure, hindering early coordination at a regional level. Women are treated mainly as victims, despite some voluntarily joining and playing active roles in Boko Haram, including volunteering as suicide bombers. DDRRR implementation in the LCB has revealed gaps in legal frameworks that require revisions. DDRRR lacks public support in some LCB countries, as many people view it as blanket amnesty for Boko Haram members. 

Recommendations Non-military means of countering violent extremism should incorporate incentives and opportunities for associates to leave these armed groups. By depleting these groups’ human resources, their fighting capacity is reduced. To encourage defection, clear processes for screening, prosecution and integration are needed. National ownership of these processes, inclusivity, adaptation to local context and adequate resourcing are key, from inception to implementation. National ownership should not lead to isolated approaches, but rather create bridges between countries to enable a cohesive regional approach. Organisations such as the Economic Community of West African States, the Liptako-Gourma States Integrated Development Authority, the G5 Sahel and the Accra Initiative could offer relevant regional frameworks for this. Authorities in charge of DDRRR programmes should consider the diverse needs and backgrounds of ex-associates. Distinguishing individuals according to why they joined and their roles within the groups is important for providing appropriate treatment. The specific needs of women and children should be taken into account. Affected West African countries should proactively formulate relevant legal and institutional frameworks. International and regional provisions and standards should be taken into account, including the need for transparent and predictable screening, prosecution and rehabilitation processes. Due to their position connecting the LCB and West Africa, Niger and Nigeria could play a key role in sharing lessons learned from DDRRR implementation. Community organisations, platforms, and media should be used by the DDRRR authorities to raise public awareness of the reintegration process. This would help prevent perceptions of general amnesty for Boko Haram members and preconceived ideas about the disengaged from undermining the process.

Extremely Confused :The Government’s new counter-extremism review revealed

By Andrew Gilligan and Paul Stott

  • The Government’s “Rapid Analytical Sprint” to determine its policy on extremism has been leaked to Policy Exchange. • It says the UK’s approach to extremism should no longer be based on “ideologies of concern” but on a very wide range of “behaviours,” including violence against women and girls, “spreading misinformation and conspiracy theories,” an interest in gore or extreme violence, misogyny, or involvement in “an online subculture called the manosphere.” It admits itself that many who display such behaviours are not extremist. • This approach could swamp already stretched counter-extremism staff and counter-terror police with thousands of new cases, increasing the risk that genuinely dangerous individuals are missed. It risks addressing symptoms, not causes. • The Sprint de-centres and downplays Islamism, by far the greatest threat to national security. It acknowledges “left-wing, anarchist and single issue (LASI) extremism,” “environmental extremism” and Hindu extremism as distinct phenomena that counter-extremist policy should tackle. The left may object to the first two; others will welcome it. • The Sprint will raise concerns over freedom of speech. It says claims of two-tier policing are a “right-wing extremist narrative.” It recommends the reversal of moves to cut police use of “non-crime hate incidents.” A new crime of making “harmful communications” online – rejected by the previous government on freedom of speech grounds - is floated. • The Sprint may have been influenced by the events of Southport. But as in the Prime Minister’s remarks after the killer’s guilty pleas last week, it risks confusing extreme violence with extremism, or extremism with any shocking crime, bad belief or nasty social phenomenon about which we are worried. • What happened in Southport was more an operational than a policy failing. The murderer had shown he was dangerous many times over several years before he killed anyone. In a more operationally effective policing and justice system, action would have been taken against him sooner, even without having to first label him an extremist. • There is a case, as the former counter-terror policing chief Neil Basu has said, for creating a “non-extremist” version of Prevent aiming to interdict people, such as the Southport killer, with an interest  in violence but no obvious ideological or political motivation. The recommendation by a previous reviewer of Prevent, William Shawcross, that the current programme is the wrong place for dealing with the psychologically unstable has been ignored, even repudiated, in the Sprint. It should be acted on. • There are several sensible proposals, including the creation of a new Ministerial Counter-Extremism Board to coordinate policy.

Catch 22: Institutional Ethics and Researcher Welfare Within Online Extremism and Terrorism Research

ByJoe Whittaker, Elizabeth Pearson, Ashley A Mattheis, Till Baaken, Sara Zeiger, Farangiz Atamuradova, Maura Conway

Drawing from interviews with 39 online extremism and terrorism researchers, this article provides an empirical analysis of these researchers’ experiences with institutional ethics processes. Discussed are the harms that these researchers face in the course of their work, including trolling, doxing, and mental and emotional trauma arising from exposure to terrorist content, which highlight the need for an emphasis on researcher welfare. We find that researcher welfare is a neglected aspect of ethics review processes however, with most interviewees not required to gain ethics approval for their research resulting in very little attention to researcher welfare issues. Interviewees were frustrated with ethics processes, indicating that committees oftentimes lacked the requisite knowledge to make informed ethical decisions. Highlighted by interviewees too was a concern that greater emphasis on researcher welfare could result in blockages to their ‘risky’ research, creating a ‘Catch 22’: interviewees would like more emphasis on their (and colleagues’) welfare and provision of concomitant supports, but feel that increased oversight would make gaining ethics approval for their research more difficult, or even impossible. We offer suggestions for breaking the impasse, including more interactions between ethics committees and researchers; development of tailored guidelines; and more case studies reflecting on ethics processes.

The Lone Wolf Threat Posed by Former JI Members

By Irfan Idris and Kusumasari Ayuningtyas

The ideological influence of Jemaah Islamiyah continues to be a threat to security even after its disbandment in June 2024. Some of its former members may align with other extremist groups, while others may seek to operate as lone-wolf terrorists. The possibility of JI’s former members transitioning into lone wolf actors stems from the enduring power of its ideology and indoctrination process.

Reclaiming Asabiya to Counter Extremism and Foster Unity

By Noor Huda Ismail

The concept of asabiyya – group solidarity – originally articulated by Ibn Khaldun, has been hijacked by extremist groups in Southeast Asia to create division and promote radical ideologies. Reclaiming asabiya is crucial, redefining it as a tool for social cohesion and unity by drawing on cultural values that foster mutual respect and collective responsibility. Regional cooperation and digital counter-narratives are essential in countering extremism and fostering long-term peace in the region.

Understanding EU Counter-Terrorism Policy

By Piotr Bąkowski


Faced with a persistent terrorist threat, the European Union (EU) is playing an increasingly ambitious role in counter-terrorism. While primary responsibility for combating crime and ensuring security lies with the Member States, the EU provides cooperation, coordination and (to some extent) harmonisation, as well as financial support, to address this borderless phenomenon. Moreover, awareness of the connection between development and stability, as well as between internal and external security, has come to shape EU action beyond Union borders. EU spending on counter-terrorism has increased over the years, to allow for better cooperation between national law enforcement authorities and enhanced support by the EU bodies in charge of security and justice, such as Europol, eu-LISA and Eurojust. The many new rules and instruments that have been adopted in recent years focus, among other things, on harmonising definitions of terrorist offences and sanctions, sharing information and data, protecting borders, countering terrorist financing and regulating firearms. However, implementing and evaluating the various measures is a challenging task. The European Parliament has played an active role not only in shaping legislation, but also in evaluating existing tools and gaps through the work accomplished by its Special Committee on Terrorism (TERR) in 2018. In line with the Parliament's recommendations, as well as the priorities set by the European Commission and its counter-terrorism agenda presented in December 2020, EU counter-terrorism action has focused on doing more to anticipate threats, counter radicalisation, and reduce vulnerabilities by making critical infrastructures more resilient and improving the protection of public spaces. The EU will also continue to address the online dimension of various forms of extremism, in line with the regulations on dissemination of terrorist content online and on the provision of digital services in the EU. This briefing updates an earlier one, entitled Understanding EU counter-terrorism policy, published in 2023.

Disinformation and Cognitive Warfare

By Alana Ford

An examination of the threat of disinformation and cognitive warfare in the Indo-Pacific, the brief unpacks how these tactics are reshaping national security and undermining democratic institutions. Drawing on global examples, it highlights the implications for regional stability and democratic resilience.

The briefing paper outlines Australia’s multipronged approach, including legislative reforms, international partnerships, and public education efforts, offering practical insights to counter these evolving security threats and safeguard democratic values across the Indo-Pacific.

Key messages

Disinformation and cognitive warfare are evolving security threats that undermine democratic institutions, polarise societies, and manipulate public trust at a global scale.

The digital revolution has amplified the speed, precision, and scale of disinformation campaigns.

Russia’s invasion of Ukraine demonstrates how cognitive warfare is deployed to legitimize unlawful acts of aggression and manipulate international narratives.

Democracies in the Indo-Pacific, including Australia, face heightened risks of disinformation and cognitive warfare due to their open information environments and the region’s complex geopolitical dynamics.

Effective countermeasures require coordinated domestic and international efforts, leveraging regulation and multilateral partnerships like AUKUS and the Quad.

Jihadist Terrorism in the United States: What the Data Tell Us

By Alexander Palmer, Skyeler Jackson, and Daniel Byman

Despite the recent attack in New Orleans, longer-term trends suggest that jihadist terrorism in the United States is not resurgent. The number of jihadist plots and attacks in the United States has been low since the territorial defeat of ISIS. The average lethality of jihadist terrorist attacks has also fallen since the peak of the caliphate. International groups such as the Islamic State and al Qaeda have filled more of an inspirational role rather than directly orchestrating attacks on the United States. Although formal links between attackers and plotters in the United States appear to be rare, this has not prevented individuals from carrying out lethal “lone wolf” attacks. Overall, jihadist terrorism in the United States does not merit additional resources at this time; however, international terrorism organizations continue to merit counterterrorism efforts.

The Rise of Radicalism in Bangladesh: What Needs to Be Done

By Iftekharul Bashar

In 2024, Bangladesh faces a growing threat of radicalism fuelled by political instability, security vacuums, and weakened counterterrorism infrastructure. Unless the interim government adopts a zero-tolerance policy and strengthens law enforcement and intelligence efforts, extremist groups may gain further ground, leading to long-term instability. COMMENTARY Bangladesh is facing an increasing threat of radicalism and terrorism. The political violence and instability of 2024 have worsened the situation, with extremist elements exploiting the security vacuum created by the regime change. Weakened law enforcement and intelligence agencies, along with the rise of armed groups and radical ideologies, pose a serious threat to the country’s stability. Bangladesh risks long-term insecurity with broader regional implications without swift and decisive action.

Coping with Complexity: Dealing with Non-State Armed Actors

By Yannick Deepen and Sabine Kurtenbach

Non-state armed actors (NSAAs) come in a variety of shapes and sizes, including warlordled groups, insurgencies, militias, and organised-crime syndicates to name just the most prominent examples hereof. In war or lower-level armed conflict, as well as violence-prone contexts, these groups pose acute problems for peacebuilding, democratic governance, and sustainable development. They control resources and territories, as well as compete, cooperate, or align with political and economic elites both within and beyond the state to promote the unstable status quo that serves their interests. Various challenges arise when dealing with NSAAs. Prevailing strategies vary between repression, co-optation, and submission to the rule of law. This analysis maps cross-regional trends regarding NSAAs based on available datasets. On this basis we develop a typology for NSAAs and a conceptual frame for their transformation. We then apply this to three paradigmatic case studies – Colombia, Mali, the Philippines – and formulate recommendations for the designing of improved strategies vis-à-vis development cooperation and other external actors.

How ISIS Fights: Military Tactics in Iraq, Syria, Libya and Egypt

By Omar Ashour

How did ISIS – a widely hated, massively outnumbered and ludicrously outgunned organisation – manage to occupy over 120 cities, towns and villages from the Southern Philippines to Western Libya? Seeking to understand ISIS’s combat effectiveness, Omar Ashour analyses the military and tactical innovations of ISIS and their predecessors in Iraq, Syria, Libya and Egypt. He shows how their capacity to mix conventional military tactics with innovative guerrilla warfare and urban terrorism strategies allowed ISIS to expand and endure beyond expectations.

Staunching The Rise of Terrorist Fighters

By Rohan Gunaratna

The conflicts in Israel, Gaza, Lebanon, Yemen and Syria will have a generational impact. The 7 October 2023 attack against Israel in Gaza and its consequences have set back the prospects of a two-state solution to the Palestinian issue and may attract a new wave of foreign fighters to embark on terrorist activities like what was seen following the military debacles in Afghanistan, Iraq and Syria. What can be done to stem another rise of the terrorist fighters?

Urban Terrorism in Contemporary Europe: Remembering, Imagining and Anticipating Violence

Edited by Katharina Karcher, Yordanka Dimcheva ,· Mireya Toribio Medina. Mia Parkes

This open access book sheds light on collective practices of remembering, imagining and anticipating in relation to recent acts of urban terrorism in Europe. Analysing a range of personal and collective responses to urban terrorism in contemporary Europe, this book shows that current debates on this issue are shaped by multiple co-existing and intersecting memories of political violence in the past. Moreover, despite public declarations of unity and solidarity, collective memories of urban terror in contemporary Europe are far from consensual - memory can be both a catalyst for and an impediment to social and political change. Drawing on case studies from a range of European countries and creative responses by survivors, artists, and poets, this interdisciplinary volume introduces readers to key methods (e.g. discourse analysis and (auto-)ethnography) and concepts (e.g. Lieux de Mémoire and ‘grassroots memorials’) for the study of the memorialization of terror attacks.

Profiles of Individual Radicalization in the United States (PIRUS): Mass Casualty Extremist Offenders

By Michael Jensen, Sheehan Kane, and Elena Akers

Included with the current update to the Profiles of Individual Radicalization in the United States (PIRUS) data are a suite of variables that allow users to investigate extremist offenders who plotted to commit, or committed, mass casualty attacks in the United States from 1990-2021. A mass casualty plot is defined as an event in which the perpetrator(s) intended to kill or injure four or more victims. Unlike other data resources on mass casualty events, PIRUS allows users to investigate successful mass casualty attacks as well as unsuccessful plots where the perpetrators clearly intended to kill or injure four or more people but failed. The inclusion of failed and foiled mass casualty plots in PIRUS gives users a more accurate estimate of how often extremists plan to cause significant harm. It also allows users to compare ideological groups and offenders on measures of plot success. This research brief provides an overview of the mass casualty crimes in PIRUS, including their frequency, links to ideological and sub-ideological groups, and a comparison of their perpetrators.

Global Terrorism Threat Forecast 2025

By Rohan Gunaratna

SYNOPSIS As we enter the new year, armed conflicts continue to rage across the globe, destabilising nations, regions, and even the global order. Terrorist attacks and state responses create ripple effects, which not only shape the battlefields but redefine states, fragment societies, and radicalise communities. What does the terrorism threat landscape look like in 2025?

COMMENTARY Global terrorism will remain a persistent and pervasive threat to the stability and peace of the world. The Islamic State, Al Qaeda, and Iran-sponsored Shiite and Sunni militia have exacerbated instability around the globe, while geopolitical competitions have polarised and fragmented the community of nations. Unless governments work together to mitigate common security challenges, threat actors will exploit the gaps, loopholes, and weaknesses in global security systems. All nations need to be steadfast in preventing and preempting threats from taking root and facing up to threats from state and non-state actors including lone wolf attackers. In addition to disinformation operations, threat actors will attack information infrastructure. Nations will need to secure the online domain as hostile states increase their cyberattacks, sabotage infrastructure, assassinate public officials, and engage in espionage.

Risk and Protective Factors Associated With Support of Violent Radicalization: Variations by Geographic Location

By Heidi Ellis , Alisa B. Miller , Georgios Sideridis , Rochelle Frounfelker , Diana Miconi , Saida Abdi , Farah Aw-Osman and Cecile Rousseau

Objectives: We examine the association between perceived discrimination, mental health, social support, and support for violent radicalization (VR) in young adults from three locations across two countries: Montréal and Toronto, Canada, and Boston, United States. A secondary goal is to test the moderating role of location. Methods: A total of 791 young adults between the ages of 18 and 30, drawn from the Somali Youth longitudinal study and a Canada-based study of college students, participated in the study. We used multivariate linear regression to assess the association between scores on the Radical Intentions Scale (RIS) with demographic characteristics, anxiety, depression, social support, and discrimination. Results: In the full sample, discrimination, age, and gender were associated with RIS scores. When we examined moderation effects by location, RIS scores were associated with depression only in Montréal, and with social support (negatively) and discrimination in Toronto. None of the variables were significant in Boston. Conclusion: These findings suggest that an understanding of risk and protective factors for support of VR may be context-dependent. Further research should take into consideration local/regional differences

Cognitive and Behavioral Radicalization: A Systematic Review of the Putative Risk and Protective Factors

By Michael Wolfowicz, Yael Litmanovitz, David Weisburd, and Badi Hasisi

Abstract Background: Two of the most central questions in radicalization research are, (1)why do some individuals radicalize when most of those from the same groups or exposed to similar conditions do not? and (2) why do radicalized individuals turn to radical violence while the majority remain inert? It has been suggested that the answer to both questions lie in the cumulative and interactive effects of a range of risk factors. While risk assessment and counter‐radicalization take a risk‐protectivefactor approach, there is widespread debate as to what these factors are and which are most important.Objectives: This review has two primary objectives.1) To identify what the putative risk and protective factors for different radica-lization outcomes are, without any predeterminations.2) To synthesize the evidence and identify the relative magnitude of the effects of different factors.The review's secondary objectives are to:1) Identify consistencies in the estimates of factors across different radicalizationoutcomes.2) Identify whether any significant heterogeneity exists within factors between(a) geographic regions, and (b) strains of radicalizing ideologies.Search Methods: Over 20 databases were searched for both published and gray literature. In order to provide a more comprehensive review, supplementary sear-ches were conducted in two German and one Dutch database. Reference harvesting was conducted from previous reviews and contact was made with leading researchers to identify and acquire missing or unpublished studies.Selection Criteria: The review included observational studies assessing the out-comes of radical attitudes, intentions, and/or radical behaviors in OECD countries and which provided sufficient data to calculate effect sizes for individual‐level risk and protective factors.Data Collection and Analysis: One‐hundred and twenty‐seven studies, containing 206 samples met the inclusion criteria and provided 1302 effect sizes pertaining to over 100 different factors. Random effects meta‐analyses were carried out for each factor, and meta‐regression and moderator analysis were used to explore differ-ences across studies.Results: Studies were primarily cross‐sectional, with samples representing 20 OECD countries. Most studies examined no specific radicalizing ideology, while others focussed on specific ideologies (e.g., Islamist, right‐wing, and left‐wing ideologies). The studies generally demonstrated low risk of bias and utilized validated or widely acceptable measures for both indicators and outcomes.With some exceptions, sociodemographic factors tend to have the smallest estimates, with larger estimates for experiential and attitudinal factors, followed by traditional criminogenic and psychological factors.Authors' Conclusions: While sociodemographic factors are the most commonly examined factors (selective availability), they also tend to have the smallest es-timates. So too, attitudinal and even experiential factors, do not have effect sizes of the magnitude that could lead to significant reductions in risk through tar-geting by interventions. Conversely, traditional criminogenic factors, as well as psychological factors tend to display the largest estimates. These findings suggest the need to broaden the scope of factors considered in both risk assessment and intervention, and this review provides much needed evidence for guiding the selection of factors
