The role which policy makers can play in the fight against radicalisation is clear. They must support the work of the other front line groups identified by this project, and they must give prevention priority in their agenda.

TERRA will gather the state of the art of international research on this subject, and combine it with the expertise of the pool of academics, former terrorists and victims of terrorism to produce guidelines for European policy makers.
