The Task Force's final report is divided into two primary sections. The Introduction provides background on the foreign fighter phenomenon, an assessment of why it is a threat to the United States, and an analysis of 58 case studies of Americans who traveled or attempted to travel to fight in Syria and Iraq. The Key Findings & Recommendations section outlines the Task Force's main conclusions and is sub-divided into four parts: (1) U.S. government strategy and planning to combat the threat; (2) efforts to identify terrorist and foreign fighters -- and prevent them from traveling; (3) efforts to detect and disrupt terrorists and foreign fighters when they travel; and (4) overseas security gaps.
