'Through its systematic engagement with a variety of ideas and cases, this collection of important work provides a central point of focus for scholars and practitioners seeking to engage with the questions and debates surrounding radicalisation and jihadi violence. Jihadi Terrorism and the Radicalisation Challenge represents the capstone to the current phase of research on this subject, and essential reading for all in this field.' Jonathan Githens-Mazer, Institute of Arab and Islamic Studies, University of Exeter, UK 'In the literature on Jihadism, Rik Coolsaet's contribution as the editor of the book Jihadi Terrorism and the Radicalization Challenge: European and American Experiences stands apart. Many outstanding scholars took part in its writing and they brought in new ideas not only on Jihadism and radicalization but also on the de-radicalization process and its intricacies.
