This report looks in greater depth at the phenomenon of global jihadism and how it manifests itself in the Netherlands. It addresses the question of what global jihadism actually involves and what factors have led to its current revival. We must try to understand jihadism and the form it takes in the Netherlands: an understanding of this phenomenon, and of its underlying processes and motives, is a vital prerequisite for devising an appropriate approach. This analysis therefore starts with the ideology behind jihadism. It will also reflect on the process of radicalisation that occurs before a person embraces extremist views. After all, in order to intervene effectively to halt radicalisation it is important to understand the potential appeal of extremist ideas and why some people are susceptible to them.
