In this cogent and thoughtful work, Angela Lahr argues that the politically-charged environment of Cold War America provided American evangelical Christians with the opportunity to enter the political mainstream in the decades after World War Two. She analyses specific case studies of Cold War flashpoints, including the development of the atomic bomb, the creation of the state of Israel, the global reach of US rivalry with the USSR and the Cuban Missile Crisis, and shows how Christian eschatological debates dovetailed with conservative interpretations of the American role in combating global Communism. Evangelical organisations that preached the second coming of Christ or the imminent end of the known universe found a helpful catalyst in the apocalyptic tenor of Cold War political debate in the 1950s and early 1960s, which helped to set fundamentalist religious belief at the centre of American political culture in these years. In a final chapter Lahr deftly outlines the emergent cracks in the perceived uniformity of Christian political engagement in the tumultuous years of the civil rights movements and the Vietnam War, reminding the reader that the social gospel preached by some evangelicals rendered Christian thought and practice as open to being harnessed by liberals as by right-wing conservatives. Throughout the book she is careful to draw careful, nuanced distinctions between the various outlooks of different organisations and personalities, and her introductory chapter provides a useful outline of the historical context to Protestant religious thought in the United States. Lahr is well-versed in eschatological theory and explains the significance of millennialism and its variants in evangelical discourse. Each chapter is thematic in scope, occasionally forcing Lahr to place together examples of Christian political engagement from very different political contexts and time periods. But the overall effect of this elegantly argued book is to force historians to think in more sophisticated fashion about the development of political evangelicalism in the United States over the last fifty years, and its impact on American political culture.
