This engaging new supplementary book critiques six alternative prescriptions or "logics" of the United States' role in the world: hegemonism, realism, isolationism, liberalism, liberal internationalism, and radical anti-imperialism. This new book presents each of six "logics"--sets of beliefs about foreign policy strategy, national interest, power, and ethical obligations--arguing a balanced and compelling case for each one. It then traces the role of each logic in the history of U.S. diplomacy and concludes with a critical evaluation of that logic.
