Social network analysis can be a powerful tool to better understand the social context of terrorist activities, and it may also offer potential leads for agencies to intervene. Our access to Dutch police information allows us to analyse the relational features of two networks that include actors who planned acts of terrorism and were active in the dissemination of a Salafi-Jihadi interpretation of Islam (n = 57; n = 26). Based on a mixed-method approach that combines qualitative and more formal statistical analysis (exponential random graph models), we analyse the structural characteristics of these networks, individual positions and the extent to which radical leaders, pre-existing family and friendship ties and radicalizing settings affect actors to form ties. We find that both networks resemble a core–periphery structure, with cores formed by a densely interconnected group of actors who frequently meet in radicalizing settings. Based on our findings, we discuss the potential effects of preventive and repressive measures developed within the Dutch counterterrorism framework.
Despite the widely held notion that processes of radicalization tend to happen in relation to others, systematic evidence on the social context in which actors meet and form ties is scarce. This is problematic, as without a more thorough understanding of the relational dimension of radicalization, any strategy to intervene may turn out less effective than perhaps hoped for. Based on our access to detailed police information on eleven Dutch Salafi-Jihadi networks (2001–2014; 273 actors), this article presents a descriptive analysis of the social context in which actors meet and form ties. In most networks, we observe pre-existing family and friendship ties, actors to frequent Salafi mosques and radicalizing settings, and committed actors engaged in functional roles. We also find indications for these elements to facilitate actors to form ties. It is important to note however that we also observe exceptions, both in terms of prevalence and impact of the relational factors we study. In the article, we describe our detailed empirical findings and reflect on the (differential) social context is which actors participating in Dutch Salafi-Jihadi networks meet and form ties.
Research has shown that irregular migrants were disproportionally present in jihadi networks in the Netherlands between 2001 and 2005. Building on this study, by analysing files of closed criminal investigations and interviewing imams and personnel within asylum seeker centres and detention centres, this article explains the attractiveness of jihadi networks by a combination of pragmatic and ideological factors. The studied cases demonstrate how jihadi networks are able to satisfy certain needs of these irregular immigrants in a pragmatic way and how criminal activities play an important role in this process. They also show how jihadi networks can fill a void for some of these irregular migrants who are in search for meaning and identity. The Jihadi-Salafi ideology does not seem to be the core pull factor explaining the attractiveness of the jihadi networks in this study.
