An excellent new report on violent far-right extremists, published by the Combating Terrorism Center at West Point, is available here.
This study provides a conceptual foundation for understanding different far-right groups and then presents the empirical analysis of violent incidents to identify those perpetrating attacks and their associated trends. Through a comprehensive look at the data, this study addresses three core questions: (1) What are the main current characteristics of the violence produced by the far right? (2) What type of far-right groups are more prone than others to engage in violence? How are characteristics of particular far-right groups correlated with their tendency to engage in violence? and (3) What are the social and political factors associated with the level of far-right violence? Are there political or social conditions that foster or discourage violence?
