The development of the Thai-American alliance from 1947 to 1958 dramatically transformed both countries' involvement in Southeast Asia. Bounded by two important political events in Thailand, an army coup in 1947 and the military's assumption of complete control of government in 1958, the period witnessed both the entrenchment of authoritarian military government in Thailand and a revolution in US-Thai relations. During these years the modern Thai political system emerged, and the United States established its interest and influence in mainland Southeast Asian affairs. The developments of the period made possible American's later, more extensive, involvement in Indochina. A Special Relationship provides the most comprehensive analysis of this critical founding period of the Thai-American alliance. It reveals surprising new information on joint covert operations in Indochina, American support for suppression of government opponents, and CIA involvement in Thai domestic politics.
