The rise of the Islamic State has contributed to both an increased terrorism threat in Western nations and an unprecedented number of citizens joining the group of so-called foreign fighters. IS has used the internet as a way to both disseminate propaganda and radicalize and recruit supporters. This article will begin by analyzing some of the most recent and well-known of such efforts, offering explanations for their successes and failures. The author then assesses limitations to combatting extremist ideas. Not only must the solution involve civil society, but a recalibration of the meaning and aims of counter-messaging is needed.

CSR is pleased to announce the release of its newest report, As American As Apple Pie: How Anwar al-Awlaki Became the Face of Western Jihad, by Research Fellow Alexander Meleagrou-Hitchens. This study provides the first forensic analysis of Anwar al-Awlaki’s work, which tracks his ideological path from a supposedly moderate preacher to an al-Qaeda recruiter.

This literature review seeks to reorient the discourse on radicalization to consider the connection between communication technology and violent extremism. By interrogating three central questions vexing policy-makers, law enforcement officials and academics, this review moves away from a monolithic understanding of the internet and showcases the opportunities afforded by different communications technologies within the context of radicalization and recruitment. As this discussion shows, there is a consensus that despite significant exceptions to the rule, the internet alone does not act as a radicalizing agent, but rather serves as a facilitator and catalyst for terrorist organizations and their respective networks. Despite varying analyses produced within the literature, there is agreement that the virtual sphere does not replace the real world in most instances. Above all, a review of the current literature demonstrates that to answer the crucial questions posed in this article, more empirically-based research is required. This article is a revised and updated version of the 2017 VOX-Pol report Research Perspectives on Online Radicalisation: A Literature Review 2006 to 2016.

This literature review seeks to recalibrate our understanding of online radicalisation, how it is conceptualised within the literature and the extent to which the policy debate has advanced in response to technological and legal developments. Among the findings are the following:

• In recent years, the overwhelming focus of this avenue of research has been on the global jihad movement. This is therefore reflected in the review, but an effort has also been made to highlight similar research on other movements;
• As with the wider debate on radicalisation, there is little agreement on what constitutes online radicalisation and how, if at all, it happens. The influence of online interactions and propaganda on processes of radicalisation therefore remains a highly contested subject. It is a topic that has produced a broad swathe of literature, using different methodologies from a variety of disciplines;
• Consensus is that the Internet alone is not a cause of radicalisation, but a facilitator and catalyser of an individual’s trajectory towards violent political acts; • Use of empirical evidence to draw convincing conclusions remains scarce, and this has negatively impacted on the strength of research on this topic. Nonetheless, the exponential rise in violent extremist use of social media platforms has been the catalyst for an increase in research on the topic, and has begun to provide researchers with new forms of primary source data;
• Extremist use of the Internet has rapidly evolved and effectively adapted to a constantly shifting online media environment. Indeed, organisations – both public and private – that seek to respond to this are still playing catch-up, and have yet to mount a convincing response;
• One of the most celebrated aspects of social media – its ability to tailor content that appears on users’ feeds that appeals to their specific values and interests and plugs them into networks of like-minded individuals – is also what makes it a key asset for extremist groups. Both in the physical and virtual realm, such groups rely heavily upon isolating potential recruits from views and opinions that diverge from their prevailing ideologies and narratives. Extremists seek to insert people into echo chambers that amplify their message and suppress any contrary opinions. Thus, by its very nature, social media creates for its users an environment that, in some cases, is conducive to radicalisation. This is neither a criticism of social media companies nor a call for them to fundamentally change the services they provide, but rather a comment on the complexity of the challenge of online radicalisation;
• While some analysts and scholars call for measures such as censorship, others argue that softer approaches, such as creating online so-called ‘counter-narratives’ and educating Internet users, would be more effective. However, it is clear that there remains both a lack of understanding of how this would occur, or how such narratives could be effectively disseminated. While very few studies provide a convincing explanation of either, there are signs that a more sophisticated approach is beginning to take shape.

While the threat that al-Shabaab poses to the West can easily be overstated, its outreach to Muslims living in Europe and the United States has been successful relative to other al-Qaeda-linked groups and warrants exploration. The organisation has recruited dozens of foreign fighters from the West (see Appendix). It also holds the dubious distinction of being the first jihadist organisation to recruit an American citizen to commit an act of suicide terrorism. Its recruitment strategy is therefore worthy of examination as a case study of how jihadist groups formulate strategies to lure Western Muslims. Through a combination of primary source analysis, background interviews in East Africa and an in-depth quantitative analysis of the group’s Twitter output, this paper aims to go beyond the simple statement of this problem by explaining how al-Shabaab markets itself to Muslims beyond its borders and what methods it employs. It also explores how the group is using social media to engage its followers in ways that other actors in the global jihad movement have not yet mastered.

This article examines the forms and feelings of togetherness evident in both Manchester city centre and on social media during the first anniversary of the 22 May 2017 Manchester Arena bombing. To do this, we introduce a conceptual framework that conceives commemorative public atmospheres as composed of a combination of ‘more or less digital’ elements. We also present a methodological approach that combines the computational collection and analysis of Twitter content with short-term team autoethnography. First, the article addresses the concept of public atmospheres before introducing the case study and outlining our methodology. We then analyse the shifting moods of togetherness created by the official programme of commemorative events known as Manchester Together and their digital mediatisation through Twitter. We then explore a grassroots initiative, #LoveMCRBees, and how it relied on the materialisation of social media logics to connect people. Overall, we demonstrate how public atmospheres, as constituted in more and less digital ways, provide a framework for conceptualising commemorative events, and how togetherness is reworked by social media, especially in the context of responses to terrorism.
