This report builds on the Prevention Project’s December 2016 report, “Communities First: A Blueprint for Organizing and Sustaining a Global Movement against Violent Extremism,” and is informed by a series of consultations with scores of governmental and non-governmental P/CVE stakeholders over the past 18 months. It takes stock of the progress and challenges in advancing the “whole of society” P/CVE agenda, which picked up considerable political momentum in 2015, and concludes with a series of practical, policy-relevant recommendations for enhancing its impact.
