Most of the local societies in which Al-Qaida and its affiliates and offshoots operate in the Middle East and Africa have a predominantly tribal or at least have a strong tribal component (Iraq, Yemen, Libya, Syria, Somalia, Mali, and Sinai). Countering Al-Qaida's continuing presence, therefore, requires addressing the tribal milieu and understanding Al-Qaida's critical vulnerabilities when it operates in tribal societies. In this context, the capability that tribally-based militias provide may be one of the most effective tools against Al-Qaida, and may offer a cost-effective mechanism serving as a force multiplier for U.S. forces. It could reduce the need for U.S. force commitment on the ground in environments that might offer unfavorable conditions for a U.S. Landpower footprint.
