The Terrorist Diaspora: After the Fall of the Caliphate


As ISIS continues to experience battle field losses in Iraq and Syria, experts believe there already is and will continue to be a “terrorist diaspora” from the conflict zone. As part of this diaspora, foreign fighters will spread across the globe, with some traveling to new conflict zones while others return to their countries of origin. Terrorists, including foreign fighter returnees, have already shown the ability to strike the West, especially Europe, carrying out attacks at an unprecedented pace in the United Kingdom, France, and Belgium, among other countries. This hearing will examine the current terror threat landscape, how the “terrorist diaspora” will affect the security of the homeland and the West, and what additional measures the U.S. can take to prevent this threat from spilling over into the homeland.
