America's Miracle Man in Vietnam rethinks the motivations behind one of the most ruinous foreign-policy decisions of the postwar era: America's commitment to preserve an independent South Vietnam under the premiership of Ngo Dinh Diem. The so-called Diem experiment is usually ascribed to U.S. anticommunism and an absence of other candidates for South Vietnam's highest office. Challenging those explanations, Seth Jacobs utilizes religion and race as categories of analysis to argue that the alliance with Diem cannot be understood apart from America's mid-century religious revival and policymakers' perceptions of Asians. Jacobs contends that Diem's Catholicism and the extent to which he violated American notions of "Oriental" passivity and moral laxity made him a more attractive ally to Washington than many non-Christian South Vietnamese with greater administrative experience and popular support.
