The same aspects of American government and society that propelled the United States to global primacy have also hampered its orderly and successful conduct of foreign policy. This paradox challenges U.S. leaders to overcome threats to America's world power in the face of fast-moving global developments and political upheavals at home. The fully updated Fifth Edition of Steven W. Hook’s U.S. Foreign Policy: The Paradox of World Power explores this paradox, identifies its key sources and manifestations, and considers its future implications as it asks whether U.S. foreign policymakers can manage these dynamics in a manner that preserves U.S. primacy.
