In Buddha's Company explores a previously neglected aspect of the Vietnam War: the experiences of the Thai troops who served there and the attitudes and beliefs that motivated them to volunteer. Thailand sent nearly 40,000 volunteer soldiers to South Vietnam to serve alongside the Free World Forces in the conflict, but unlike the other foreign participants, the Thais came armed with historical and cultural knowledge of the region. Blending the methodologies of cultural history and ethnography, Richard Ruth examines the individual experiences of Thai volunteers in their wartime encounters with American allies, South Vietnamese civilians, and Viet Cong enemies. Ruth shows how the Thais were transformed by living amongst the modern goods and war machinery of the Americans and by traversing the jungle haunted by indigenous spirits. At the same time, Ruth argues, Thailand's ruling institutions used the image of volunteers to advance their respective agendas, especially those related to anticommunist authoritarianism. Drawing on numerous interviews with Thai veterans and archival material from Thailand and the United States, Ruth focuses on the cultural exchanges that occurred between Thai troops and their allies and enemies, presenting a Southeast Asian view of a conflict that has traditionally been studied as a Cold War event dominated by an American political agenda. The resulting study considers such diverse topics as comparative Buddhisms, alternative modernities, consumerism, celebrity, official memories vs. personal recollections, and the value of local knowledge in foreign wars. The war's effects within Thailand itself are closely considered, demonstrating that the war against communism in Vietnam, as articulated by Thai leaders, was a popular cause among nearly all segments of the population.
