• 1. The American future: problems of primacy, policy, and purpose; 2. Domestic and global interactions: economics, energy, and American power; 3. American attitudes and institutions; 4. Threats to persistent primacy and the rise of others; 5. Stretch or 'imperial overstretch'; 6. Power and willpower in the American future.

'The United States is experiencing another bout of anxiety regarding its relative power. While he is sober about the challenges confronting the nation, Robert Lieber makes a convincing case that, as in the past, fears of American decline will prove to have been greatly exaggerated. The United States has the resources necessary to continue to play the part of the world's preponderant power; the question is whether its leaders, and its people, will have the necessary wisdom and resolve. On this count, as Lieber makes plain, there is every reason for optimism.' Aaron L. Friedberg, Princeton University
