At a time when greater transparency is needed, this book advances a novel explanation of America's efforts to advance greater transparency in international relations. Marquardt argues that American statesmen have long sought to secure an American-dominated international system to encourage states to be more open and forthcoming about their internal affairs. Yet the United States routinely uses its calls for military transparency in particular as a policy instrument to discipline its rivals and therefore paradoxically contributes to greater tension in international relations. In contrast to conventional thinking about transparency in relation to overcoming power politics and promoting international cooperation, this book explores the relationship between America's power and international security competition. Though analytically distinct, openness and transparency have served the same strategic goal; ensuring America's position of preponderance in the international system.
