The Islamic State of Iraq and Syria (ISIS) considers dissemination of propaganda to be one of its most important activities—and a highly-effective recruiting tool. In particular, ISIS uses social media in unprecedented ways to enlist new members to its ranks. With this challenge in mind, this Working Group seeks to explore how the United States and the international community can adopt more effective and systematic approaches to countering ISIS propaganda. This Working Group will assess the capacity of existing counter-messaging programs, determine good practices, and identify regional challenges and opportunities to implementing such programs. Discussions will also consider how the United States and its allies can apply lessons from other countries which have confronted violent extremism. The goal of this Working Group is to develop recommendations for national and regional strategies which can empower civil society and other local actors as a bulwark against extremist propaganda.
