This seventh publication in the Historical Analysis Series addresses the American role in the Philippine Hukbalahap Insurrection. Brought to the verge of collapse by a wide-spread Communist-inspired insurgency, the government of the Philippines, supported by limited U.S. aid, advice, and assistance, virtually eliminated Huk resistance by 1955. This study examines this remarkable achievement and demonstrates how efforts of uniquely qualified individuals, combined with American foreign policy initiatives and international events, prevented the collapse of an important allied nation.
