Jack Snyder is a leading American international relations scholar with an international reputation for his research on IR theory and US Foreign policy. This book collects many of his most important essays into a single volume. Exploring a liberal realist theory of international politics, the book is arranged around three key subject areas: * Anarchy and Its Effects * The Challenges of Democratic Consolidation * Empire and the Promotion of a Liberal Order With a new introduction to frame the selected essays, this collection examines how developing nations evolve political systems, and fit into a world dominated by liberal-democracies. It looks to the future for the current dominant powers in a changing world of international relations and at the challenges to their leadership. Featuring a new conclusion, developed from the assembled chapters, this is a fascinating and vital collection of scholarship from one of the most influential theorists of his generation. Power and Progress is an invaluable text for students and scholars of international relations, and those interested in the debates on liberalism and realism, and comparative politics.
