This year we offered a new format featuring a discussion moderated by WHYY’s Marty Moss-Coane, with guests Trudy Rubin, the renowned columnist of the Philadelphia Inquirer, and Clint Watts, FPRI’s own “online jihadi hunter” and Robert A. Fox Fellow. In this discussion, we explored the threat posed by ISIS at home and abroad, the interconnection with the Syrian civil war, the phenomenon of foreign fighters, and the question of radicalization.
