To support the U.S. Department of Defense (DoD)'s efforts to counter extremism in its ranks, the authors considered how a terrorism prevention or countering violent extremism framework might address the issue. They offer intervention initiatives that DoD might consider adopting. They also review the terrorism prevention framework as it has been applied in the U.S. civilian sector and focus on initiatives that might be relevant and adaptable to the military context.

This review highlights broader evidence for such initiatives, places the initiatives in the context of the radicalization process and in the context of other such initiatives, and offers at least a cursory review of the evidence base for interventions.

This study first examined the relevant literature and assessed the current knowledge regarding the dynamics of terrorism. The researchers then developed psychological and sociological profiles of foreign terrorist individuals and selected groups to use as case studies in assessing trends, motivations, likely behavior, and actions that might deter such behavior and reveal vulnerabilities to be targeted by countermeasures… A review of the literature suggests that the psychological approach by itself is insufficient to understand what motivates terrorists; an interdisciplinary approach is required to understand terrorist motivation. Terrorists are motivated not only by psychological factors but also by political, social, religious, and economic factors, among others. These factors vary widely. Each terrorist group must be examined within its own cultural, economic, political, and social context in order to better understand the motivations of its individual members and leaders, along with their particular ideologies…. Some counterterrorist measures proposed are psychological warfare to divide political and military leaders and factions, the identification and capture of a top hard-line terrorist or guerrilla leader, and the avoidance of actions that will fuel recruitment. The latter recommendation means that legal, political, diplomatic, financial, and psychological warfare may be more effective than retaliation against terrorists with bombs or cruise missiles.

Al-Qaeda and allied groups continue to pose a threat to the United States. Although it is less severe than the catastrophic proportions of a 9/11-like attack, the threat today is more complex and more diverse than at any time over the past nine years. Al-Qaeda or its allies continue to have the capacity to kill dozens, or even hundreds, of Americans in a single attack. A key shift in the past couple of years is the increasingly prominent role in planning and operations that U.S. citizens and residents have played in the leadership of al-Qaeda and aligned groups, and the higher numbers of Americans attaching themselves to these groups. Another development is the increasing diversification of the types of U.S.-based jihadist militants, and the groups with which those militants have affiliated. Indeed, these jihadists do not fit any particular ethnic, economic, educational, or social profile. Al-Qaeda’s ideological influence on other jihadist groups is on the rise in South Asia and has continued to extend into countries like Yemen and Somalia; al-Qaeda’s top leaders are still at large, and American overreactions to even unsuccessful terrorist attacks arguably have played, however inadvertently, into the hands of the jihadists. Working against al-Qaeda and allied groups are the ramped-up campaign of drone attacks in Pakistan, increasingly negative Pakistani attitudes and actions against the militants based on their territory, which are mirrored by increasingly hostile attitudes toward alQaeda and allied groups in the Muslim world in general, and the fact that erstwhile militant allies have now also turned against al-Qaeda. This report is based on interviews with a wide range of senior U.S. counterterrorism officials at both the federal and local levels, and embracing the policy, intelligence, and law enforcement communities, supplemented by the authors’ own research.

The Internet has revolutionized the way all of us communicate and do business. Its benefits to people everywhere have been enormous and will continue to drive progress in practically every area of life. At the same time, it should be recognized that, while being a force for good, the Internet has also come to play an important—and, in many ways, unique—role in radicalizing homegrown and domestic terrorists. Supporters of Al Qaeda, Sovereign Citizens, white supremacists and neo-Nazis, environmental and animal liberationists, and other violent extremist groups all have embraced the Internet with great enthusiasm and vigor. They are using it as a platform to spread their ideas, connect with each other, make new recruits, and incite illegal and violent actions. We believe that this trend will continue and that future terrorist attacks against the United States and its interests will involve individuals who have been radicalized—at least in part—on the Internet. As a result, countering online radicalization should continue to be a major priority for the government and its Countering Violent Extremism (CVE) efforts. The purpose of this report is to equip policy makers with a better understanding of how the Internet facilitates radicalization, in particular within the United States; an appreciation of the dilemmas and trade-offs that are involved in countering online radicalization within the United States; and ideas and best practices for making the emerging approach and strategy richer and more effective

The emergence of “violent extremism” (VE)2 as a central framework and priority adopted by most Western and non-Western government agencies. It has become the primary lens through which to describe many of their activities, especially in conflict areas around the world, even when the issues are not or are only remotely related. There is no doubt that VE narratives, especially those promoting violence in the name of Islam spread by groups such as Al-Qaeda, Al-Shabab, Taliban and Daesh, have gained strength and visibility in the last two decades (regardless of the differences in the groups’ motivation or type of justification – be it nationalism, anti-Western intervention or religion). However, it is an overstatement to solely explain the motivation for endorsing or adopting VE in Muslim societies as a result of theological factors; as explained below, there are many other factors besides religious identity and theological reasoning contributing to the phenomenon. Nevertheless, it is possible to trace historical factors that led to the creation of such groups in predominantly Muslim countries. In Afghanistan, for example, one such factor is rooted in the Cold War dynamics between the United States (US) and the USSR at the time of the Soviet invasion of Afghanistan in 1979. To fight communism, the US government mobilised local Afghan communities, which included some fighters who subsequently employed extreme Islamic religious narratives. The US’s fervent desire to prevent the spread of communism thus led to the arming of members of Afghan society who later utilised the concept of jihad against non-believers in certain Sunni interpretations.

Is the topic of violent extremism slowly turning into one on which everything has already been said, but not yet by everyone, as Karl Valentin used to wryly remark? We do not think so. While violent extremism (VE) has indeed emerged as a new buzzword and a strong funding trend over the past few years, effective strategies for addressing the phenomenon are still being forged and need to be reviewed and tested. Violent extremism’s manifestations range widely: from foreign fighters via terrorist attacks to increasingly public violence-condoning ideology and rhetoric of both secular and religious provenance. How to deal with violent extremism, and its protagonists, is therefore also becoming a major challenge for peacebuilders and conflict transformation practitioners. What specific advantages can a “transformative lens” bring – one which applies insights and learning from the peacebuilding and conflict transformation fields?

Far-right extremism remains a worrying problem across Europe. The most visible cases are those that hit the headlines, such as the discovery of the National Socialist Underground in Germany or Anders Behring Breivik’s attacks in Norway. In the past decade, both Hungary and Sweden were hit by a string of serial murders of Roma and ethnic minorities. Though attacks of this magnitude and scale remain rare, they are not unheard of. In some cases, those personally touched by these violent attacks are still fighting for justice. While high-profile and high-impact events hit the headlines, the bulk of the threat posed by the far right is felt through smaller-scale localised harassment, bullying and hate crime by extremists targeting minority communities. These kinds of incidences often go undetected, and indeed they are hard to quantify. They manifest in the sectioning off of some local areas as no-go zones for ethnic minorities, graffiti of far-right symbols on mosques and synagogues, or threats received by individual members of the community. Those carrying out these actions – far-right extremists – are a broad group, ranging from less ideological youth street gangs to neo-Nazi terrorist cells, anti-Islam activists and registered political parties. Though they differ in their aims and methods, there are some defining features: racism, xenophobia, ultra-nationalism and authoritarianism.

Savvy use of the Internet has empowered terror networks to expand their reach beyond national borders by enabling wide distribution of a compelling message and social connectivity with new audiences. Use of computer-mediated communication (CMC) has made a range of terrorist operational activities cheaper, faster, and more secure, including communications, fundraising, planning and coordination, training, information gathering and data mining, propaganda and misinformation dissemination, and radicalization and recruitment. The list is long, and not even complete. Before the Internet, terrorists seeking to communicate with one another through electronic means used telephones or radios, which could be tapped. Terrorists seeking to offer training meant congregating trainers and trainees in a fixed training location, exposing the group to capture or worse. Terrorists or their supporters engaged in fundraising or recruitment often pursued these aims in public settings. And terrorists researching a potential target often did so at public libraries and bookstores, subjecting them to surveillance in these public spaces. Now, with the Internet, all of these same activities can be conducted in relative anonymity from safe locations across the globe.

The U.S. homeland faces a multilayered threat from terrorist organizations. Homegrown jihadists account for most of the terrorist activity in the United States since 9/11. Efforts by jihadist terrorist organizations to inspire terrorist attacks in the United States have thus far yielded meager results. No American jihadist group has emerged to sustain a terrorist campaign, and there is no evidence of an active jihadist underground to support a continuing terrorist holy war. The United States has invested significant resources in preventing terrorist attacks, and authorities have been able to uncover and thwart most of the terrorist plots. This Perspective identifies 86 plots to carry out terrorist attacks and 22 actual attacks since 9/11 involving 178 planners and perpetrators. Eighty-seven percent of those planners and perpetrators had long residencies in the United States. Only four of them had come to the United States illegally, all as minors. Nationality is a poor predictor of later terrorist activity, and vetting people coming to the United States, no matter how rigorous, cannot identify those who radicalize here. Determining whether a young teenager might, more than 12 years later, turn out to be a jihadist terrorist would require the bureaucratic equivalent of divine foresight.

The emphasis of counterterrorism policy in the United States since Al Qaeda’s attacks of September 11, 2001 (9/11) has been on jihadist terrorism. However, in the last decade, domestic terrorists—people who commit crimes within the homeland and draw inspiration from U.S.-based extremist ideologies and movements—have killed American citizens and damaged property across the country. Not all of these criminals have been prosecuted under federal terrorism statutes, which does not imply that domestic terrorists are taken any less seriously than other terrorists. The Department of Justice (DOJ) and the Federal Bureau of Investigation (FBI) do not officially designate domestic terrorist organizations, but they have openly delineated domestic terrorist “threats.” These include individuals who commit crimes in the name of ideologies supporting animal rights, environmental rights, anarchism, white supremacy, anti-government ideals, black separatism, and beliefs about abortion

Based on an in-depth literature review, Research Fellow Dr. Alex P. Schmid explores the terms “radicalisation”, “de-radicalisation” and “counter-radicalisation” and the discourses surrounding them. Much of the literature on radicalisation focuses on Islamist extremism and jihadist terrorism. This is also reflected in this Research Paper which explores the relationship between radicalisation, extremism and terrorism. Historically, “radicalism” – contrary to “extremism” – does not necessarily have negative connotations, nor is it a synonym for terrorism. Schmid argues that both extremism and radicalism can only be properly assessed in relation to what is mainstream political thought in a given period. The paper further explores what we know well and what we know less well about radicalisation. It proposes to explore radicalisation not only on the micro-level of “vulnerable individuals” but also on the meso-level of the “radical milieu” and the macro-level of “radicalising public opinion and political parties”. The author reconceptualises radicalisation as a process that can occur on both sides of conflict dyads and challenges several widespread assumptions. The final section examines various counter-radicalisation and deradicalisation programmes. It concludes with a series of policy recommendations.

Once regarded as a minor hub in Mexico’s criminal economy, Veracruz is now confronting the harrowing truths from over a decade of violence and grand corruption. At least 2,750 people are believed to have disappeared in a state whose former governor is wanted for embezzlement on numerous counts. The murders of seventeen journalists from 2010 onwards are the most notorious examples of a whirlwind of killings that targeted, among others, legal professionals, police officers, potential witnesses to crimes and any civilians who dared check the ambitions of a multitude of criminal organisations and their political accomplices. A new governor from the opposition National Action Party (PAN) has promised to clean out the state and prosecute wrongdoers, fostering hopes that peace can be restored. But as economic turbulence threatens the country, and bankruptcy looms over Veracruz, strong international support will be crucial to bolster initiatives aimed at finding the bodies of the disappeared, investigating past crimes, and transforming the state’s police force and prosecution service. Veracruz is emblematic of the challenges facing the country as a whole. Threats by the new U.S. administration to curb Mexican imports and fortify the border to keep out undocumented immigrants imperils its southern neighbour’s economic prospects. Similarly, President Trump’s predilection for armed force to combat cartels ignores the harm produced by the militarisation of public security as well as its proven ineffectiveness. But Mexican voices demanding a stronger national response are hamstrung by the extreme unpopularity of political leaders and public estrangement from government. Corruption and perceived criminal complicity have undermined the legitimacy of the Mexican government at all levels, especially at the tier of the country’s 31 regional states. Baptised “viceroys” as a result of the extraordinary powers granted them during Mexico’s transition from one-party regime to multiparty democracy, state governors have also become some of the country’s most disreputable public authorities. Since 2010, eleven state governors have come under investigation for corruption. In Veracruz, an alliance between criminal groups and the highest levels of local political power paved the way to an unbridled campaign of violence through the capture of local judicial and security institutions, guaranteeing impunity for both sides. Strengthening institutional probity and capacity in Veracruz, as in the rest of Mexico, will require federal and state levels to deliver on vows to work in partnership to staunch corruption, and on their willingness to abjure short-term political and electoral advantage. With the election of the new governor, Miguel Ángel Yunes Linares, the once hegemonic Institutional Revolutionary Party (PRI) lost power in the state for the first time in over 80 years. But the PRI remains in control at the federal level and has shown wavering commitment to Yunes’ reformist plans, not least because of the importance of securing votes from the region, the country’s third most populous, in the 2018 presidential election. The state’s budgetary crisis and the new governor’s two-year mandate make it highly unlikely that the state government could accomplish sweeping reform to Veracruz’s institutions without sustained federal backing.

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. n The vast majority of right-wing terror incidents have stemmed from white supremacists and anti-government extremists (such as militia groups and sovereign citizens), with the two broad extremist movements being responsible for almost the same number of incidents (64 related to white supremacists, 63 to anti-government extremists). n Most acts were committed by small number of extremists acting on their own rather than at the behest of organized extremist groups. About half of the 150 incidents were actually committed by lone wolf offenders. n Right-wing extremists have killed 255 people in these attacks and injured over 600 more. n Overwhelmingly, firearms and explosives were the most common weapons chosen: 55 of the incidents involved use or planned use of firearms; 55 involved use of explosives. Overall, incidents involving firearms were more likely to be deadly. n Right-wing terror incidents have involved a wide array of targets, with government, law enforcement, racial and religious targets the most common. n Right-wing terror incidents occur consistently because the movements from which they emanate are mature extremist movements with deep-seated roots. The Internet has made it easier for extremists to meet each other (and thus engage in plots), as well as to self-radicalize and become lone wolf offenders. n Right-wing terrorism is a subject under-covered by the media, in part perhaps because so many right-wing terror incidents take place far from major media centers and urban areas. One consequence of this relative lack of coverage has been an inadequate awareness among policy-makers and the public alike of the threat that violent right-wing extremists pose. n If the United States does not treat right-wing extremism as a real threat, the list of right-wing terror incidents can only grow.

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 2021 murder totals were low primarily because no high-casualty extremist-related shooting spree occurred this past year. Such sprees are the main contributor to high murder totals. Most of the murders (26 of 29) were committed by right-wing extremists, which is usually the case. However, two killings were committed by Black nationalists and one by an Islamist extremist—the latter being the first such killing since 2018. Most of the 2021 murders were committed by people associated with longstanding extremist movements, such as white supremacy and the sovereign citizen movement. However, 2021 continued the trend of recent years of seeing some murders from newer types of extremism, including QAnon adherents, people associated with the toxic masculinity subculture of the “manosphere” and anti-vaccination extremists. White supremacists killed more people in 2021 than any other type of extremist, though not an outright majority, as is often the case. An in-depth look at white supremacist killings over the past 10 years demonstrates the dangers posed by alt right white supremacists and white supremacist prison gangs.

Keypoints • There are growing links between terrorist and organised crime groups who are sharing expertise and are cooperating in kidnapping, arms, drugs and human trafficking, as well as drug production, cigarette smuggling, extortion and fraud. • The growing nexus of shared tactics and methods of terror and crime groups is due to four major developments: globalization, the communication revolution through the Internet, the end of the Cold War, and the global “war on terror”. • Both terrorist and organised crime groups are leveraging the Internet for recruitment, planning, psychological operations, logistics, and fundraising. The Internet has become the platform for both organised crime and terrorists to conduct cybercrimes ranging from video piracy, credit card fraud, selling drugs, extortion, money laundering and pornography. • The growing nexus has facilitated terrorists to access automatic weapons, including stand-off weapons and explosive devices, empowering them to challenge police, land and naval forces with the latest sophisticated weaponry and intelligence. • The growing nexus of terrorism and organised crime is exacerbating efforts in war-fighting and peacemaking in Iraq and Afghanistan. Also, West Africa in general and the Sahel in particular have become a dangerous new trafficking hub uniting both terrorists and organised crime cartels across a wide and mostly ungoverned land mass. • The growing nexus of terrorism and organised crime groups is challenging international and national security by weakening democratic institutions, compromising government institutions, damaging the credibility of financial institutions and by infiltrating the formal economy, leading to increased crime and human security challenges.

Right-wing extremists (RWEs) are using the current protests over police brutality in the United States as a cover to commit terroristic acts and to grow their numbers. They present a significant danger to public safety and security and are a growing threat in the West. Despite this, the rise of right-wing extremism (a homogenized term for white ethnonationalists, alt-rights, white supremacist groups, male supremacist groups, and rightwing anti-government extremists) has not been afforded the priority and attention it justly deserves. There are three reasons for this. First, the global narrative maintains that terrorism rests almost exclusively in the hands of a balaclava-clad Salafi-jihadist holding a Kalashnikov. Second, Western right-wing media has largely pushed back against covering the rise of right-wing extremism and the media as a whole has failed to contextualize the systematic threat RWEs present. Third, the global pandemic has forced governments to focus their attention on maintaining public health and socioeconomic order and have consequently failed to see how RWEs are subversively using the pandemic to support and expand their own agenda. RWEs have utilized the lawless and unmoderated internet to reach broader audiences, disseminate literature, and target vulnerable people. They have done so quietly, pushing an ideological campaign that manifests itself under the surface of popular internet discourse, rather than the aggressive proselytizing of Salafi-jihadist groups like the Islamic State. These efforts can be understood as a kind of subversive exposure, where memes and fake news dominate discourse. This paper will analyse the scope of the RWE threat, describe their latest modus operandi, and explore how the pandemic is being instrumentalized by such groups and how the internet has become their principal tool and battleground. The paper will then provide theory and evidence for how counter-narrative programs, especially through digital disruption, can help neutralise the threat.

Right-wing extremism in the United States appears to be growing. The number of terrorist attacks by far-right perpetrators rose over the past decade, more than quadrupling between 2016 and 2017. The recent pipe bombs and the October 27, 2018, synagogue attack in Pittsburgh are symptomatic of this trend. U.S. federal and local agencies need to quickly double down to counter this threat. There has also been a rise in far-right attacks in Europe, jumping 43 percent between 2016 and 2017.

Violent right-wing extremism has resurfaced as a worrying phenomenon in Europe, with terrorism being one of its most serious and visible forms. Old and new forms of right-wing based violence have emerged in recent years, as the Utøya attack showed in 2011. This massacre served as a wake-up call for European societies and security authorities, and highlighted the dangers of right-wing terrorism in Europe, particularly for the youth. Furthermore, terrorism is not the sole form of extreme-right and hate-based violence. Conversely, the range of extreme-right related violence also includes hate crime and hate speech, two phenomena that should not be overlooked. The former is especially relevant considering the impact it has on minority groups, on women, but also on the general population. As for the latter, the increasing use of the Internet and social media platforms has facilitated the exponential dissemination of hate speech. While two decades ago, much more effort was required by individuals to gain access to extremist right-wing ideology, nowadays these ideas are spread at a much higher speed and to a much broader audience. This is not a trivial matter. The spread of hate speech has an important impact on minority groups, as the primary victims, but also on society as a whole, as it affects social cohesion and the quality of democratic debate.
