The United States currently wields unprecedented global power. Americans often assume that their global role is benevolent and their dominant position unchallenged, but other states are increasingly worried about U.S. dominance and are beginning to turn their concerns into action. In this elegant and provocative new book, Kennedy School professor and renowned scholar Stephen M. Walt analyzes the different strategies that states employ to counter U.S. power or to harness it for their own ends. These responses threaten America's ability to achieve its foreign policy goals and may eventually undermine its dominant position. To prevent this, Walt argues, the United States must adopt a foreign policy that other states welcome, rather than one that reinforces their fear of American power.
