The United States “has too much power for anyone’s good, including its own.” So argues Timothy Garton Ash, who observes that since the demise of the Soviet Union there is no countervailing force on the world scene to check the use of U.S. power. Economically, the U.S.’s “only rival is the European Union. In military power it has no rival. Its military expenditure is greater than that of the next eight largest military powers combined. . . . It would be dangerous even for an archangel to wield so much power” (New York Times, April 9).
