The Issues Since the Cold Wars end, the United States has dominated international politics. It is-as international relations scholars put it-a global hegemon. Indeed, in recent years in books and articles about U.S. foreign policy it has become commonplace to see the United States described as the most powerful actor on the international stage since the Roman Empire was at its zenith. is doubtless is true. e central question I address is whether the United States should seek to maintain its current primacy in world politics and use this preeminence to construct a new American Empire.
