The Trump Administration has released the National Strategy to Combat Terrorist Travel, which outlines how the U.S. government intends to expand coordination and maximize the full capabilities of federal departments and agencies to identify, detect, and deter terrorists from transiting international borders. The document cites returning foreign fighters from overseas terrorist groups like the Islamic State, who can bring with them battlefield experience, explosives training, and extremist motivations, as one of the most significant threats it seeks to confront. The strategy includes an appendix of federal government programs, projects, and activities designed to constrain terrorist travel.
