In recent years, substantial attention has been paid to how and why terrorism ends. The welcome development of an
increase in research on a hitherto neglected area has occurred in parallel with the increasing prevalence of a series of
innovative, ambitious yet under-examined approaches to counterterrorism. These are collectively referred to as ‘deradicalization
programs’. However, and despite the popular media coverage of these programs, basic information surrounding
even the most basic of facts pertaining to these programs remains limited.
This report presents the results of a one-year study of select de-radicalization programs and investigates a series of critical
issues surrounding assessment of the effectiveness and outcomes of these programs.
Five open-source case studies of country-specific programs (Yemen, Saudi Arabia, Northern Ireland, Colombia and Indonesia)
illustrate not only the unique, context-specific circumstances in which these programs originated and developed,
but also reveal the challenges inherent in attempts at generalization from one or more programs, including, but not
exclusive to, efforts to assess the success of these initiatives.
While the overarching purpose of this project was to identify policy-relevant issues relevant to assessing the effectiveness
of these programs, the report seeks to identify which assessment issues are: a) specific to individual countries or
cases; b) generalizable to other cases c) in order to identify those lessons that will help provide a foundation of policyrelevant
knowledge from which similar local initiatives might develop, and not be limited to any one context both for
de-radicalization and anti-radicalization strategies.
