"Professor Hampton has long been one of the most thoughtful and perceptive observers of America's security relations with Europe. In this wonderful book, Hampton provides a searching exploration of the cultural roots of Atlantic security cooperation and discord, focusing on divergent American and European historical experiences, ideological foundations, and secular-religious cultural identities. Along the way, Hampton offers a vivid and penetrating glimpse into the 'soul' that both unites and divides the West." - G. John Ikenberry, Albert G. Milbank Professor of Politics and International Affairs, Princeton University "In this masterful book, Mary Hampton provides a fascinating account of how religious and secular worldviews underpin strategic culture in the United States and Europe. It will be difficult to view transatlantic relations in the same manner after reading this book." Giacomo Chiozza, author of Anti-Americanism and the American World Order
