ABSTRACT
With only 5 percent of the world's population, the United States has had a remarkable century of success in world leadership. It produces nearly one-quarter of global wealth and has held a global military monopoly since the late 1980s. America's success is based on a dynamic economy and population, as well as an effective foreign policy. Its foreign policy has facilitated the globalization of trade and liberal democracy. American foreign policy has been the extension of its own domestic attributes. Ironically, as other countries or regions match or overtake the United States in economic clout, they do so because they have either copied the American model or used the American-supported international order to their advantage.
