"America's leadership of a liberal world order has come in for a lot of criticism lately, but there is another, more hopeful side to liberal internationalism. After the armageddon of World War II, the United States led the way in creating a global rules-based system that, for all its faults, successfully created the conditions for international prosperity and stability. This is the story Mayers tells, and he tells it well in this original, elegantly written book."Andrew Preston, Professor of History at Cambridge University and a Fellow of Clare College and author of Sword of the Spirit, Shield of Faith: Religion in American War and Diplomacy"David Mayers turns his considered and expert gaze from the United States's wartime exploits and dilemmas to what followed in the postwar world. Importantly the author skilfully crafts his account of the burgeoning Cold War before that conflict and paradigm became 'set in stone'. In other words, Mayers' text contributes to the literature on the origins of the Cold War, without it dominating a narrative looking at the United States and the postwar world where there were alternatives. The breadth of the research, and Mayers' careful attention to detail make this a most valuable contribution to the canon."- Simon Rofe, SOAS University of London"David Mayers has written that rare book, one that has both enormous historical resonance and also contemporary relevance. He has also managed to do that in a concise and readable way." Andrew Williams, St. Andrews University, International History Review
