The U.S. Embassy in Madrid welcomed Dr. Alexander Meleagrou-Hitchens, the Research Director of the Program on Extremism at George Washington University, for a three-day visit to Madrid to discuss terrorism and foreign terrorist fighters (FTF). Embassy Madrid organized three events to demonstrate how U.S.-Spain security cooperation mitigates threats to Spain and promotes stability in the region. The Embassy co-sponsored the Elcano Royal Institute’s October 24 forum on managing the repatriation, prosecution, and long-term management of detained foreign terrorist fighters, female supporters, and their children. Additionally, the Embassy organized an expert roundtable led by Meleagrou-Hitchens with academics and think tank members. Finally, Meleagrou-Hitchens discussed with 120 students at Rey Juan Carlos University how terrorist organizations have evolved in their use of the internet and encrypted messaging tools to recruit and radicalize people.
