This thesis examines, through both an anthropological analysis of the conflict and a theory of counterinsurgency, the re-emergence of the Muslim separatist groups in southern Thailand and provides both short and long term solutions for the Royal Thai government. It offers a background analysis of the historical relationship between the Thai government and Thai Muslims in order to highlight why the former separatist problem occurred in Thailand. Next, the current separatist problem is examined to determine why this issue has reoccurred and possible reasons for the government's underestimation of the situation. This thesis then addresses measures the Thai government may take to preclude a future Muslim separatist insurgency, and offers both an analysis of former measures that were successful and an appraisal of the current conditions conducive to an insurgency. Finally, the conditions necessary for a successful resolution of the Muslim separatist problem are delineated in short term and long term solutions. / Lieutenant Colonel, Royal Thai Army
