This chapter is part of an edited collection, 'Jihadi Terrorism and the Radicalisation Challenge', which is also included on this site. The reason for including this chapter separately is that it is an often-cited source in the argument that not all radicals are terrorists and not all terrorists are 'radical', a point made particularly clearly here. The main focus of the chapter (for which it is also often cited) is on de-radicalization programmes, in particular on the need for greater evaluation of these programmes (which the authors note is lacking in the majority of cases) and for greater clarity of what is meant by 'de-radicalization'.
