Recounting the actors and events of U.S. foreign policy, Robert B. Zoellick identifies five traditions that have emerged from America's encounters with the world: the importance of North America; the special roles trading, transnational, and technological relations play in defining ties with others; changing attitudes toward alliances and ways of ordering connections among states; the need for public support, especially through Congress; and the belief that American policy should serve a larger purpose. These traditions frame a closing review of post-Cold War presidencies, which Zoellick foresees serving as guideposts for the future.
