The study monitors the evolution of perceptions and opinions of the terrorist group the Islamic State (ISIS) during its involvement in Syria and Iraq in 2013-2014. Data is drawn from a web-forum discussing current Islamic affairs that followed ISIS as early as September 2013. These data are used to answer the question of whether or not there are opinion leaders facilitating the discussion of violent extremist material. An interrupted time series and ordinary least squares regression are used to address the research question by determining the most impactful events on the thread, and determining the causal role of opinion leaders on the way users connect. Results indicate that the content and success of discussion are most impacted by the involvement of opinion leaders and media related to a specific ISIS event.

This chapter critically analyses the impact of the Internet and associated technology on the rise in terrorist attacks across the US and Europe over the last two decades. To this end, the chapter will be focusing on jihadists’ use of the Internet, yet comparisons will also be made with the radical right. Although there exist certainly differences between the groups, there are also similarities between them, and, in turn, this chapter will address these movements as a collective. The jihadist terrorist organisations that will be analysed in this chapter will include Al-Qaeda and ISIS. The findings reveal that although the Internet has been linked to the preparation and execution of attacks, as this chapter will explore, it is difficult to establish direct cause and effect associations between the Internet and the rise in attacks in Europe and the US.

This chapter critically discusses the evidence suggesting that the Internet and SMPs affect radicalisation to violent extremism. The chapter specifically focuses on arguments surrounding echo chambers, opportunities for women to remain anonymous and the role of identity construction for the youth. The study also critically discusses the evidence negating the notion that the Internet and SMPs can affect radicalisation to terrorism and violent extremism. The discussion focuses primarily on offline persuasion and a ‘false dichotomy’. Based on this critical analysis, the chapter argues that the Internet and SMPs play an important role in the radicalisation of youth and women based on the increased opportunities that might not otherwise be provided in the offline world despite the methodological issues around the evidence. Furthermore, it is argued that evidence does not successfully demonstrate that echo chambers on the Internet affect radicalisation to violent extremism. Whilst acknowledging that offline persuasion also plays a significant role and the evidence suggesting a ‘false dichotomy’, the chapter also argues that it would not be effective to research online and offline radicalisation as an integrated model. This is due to the fact that there still exists a lack of understanding and empirical research around online radicalisation as well as radicalisation in general.

The Jihadist phenomenon has a privileged space in Web 2.0 where contents can be created, networks can be global and all exchanges of information have significance. The emergent Jihadist organizations have been profiting from these digital communication features to enlarge, diversify and connect with their audience. On the one side, the virtual framing of Jihad through the manipulation of the sacred Islamic texts and its transformation into an ‘authentic’ religious discourse has given the Jihadists an opportunity to justify any religious violence associated with the performance of Jihad. On the other side, the virtual performance of Jihad through a ritualization process that combines ritualistic innovation with the use of cyber tools has allured individuals to engage and participate in Jihadist acts, both online and offline. Moreover, and in the light of the Jihadist warfare in the Middle East, the article will reveal the importance of e-Ritualization of Jihad into shaping these individual representations into a community both offline and online.
