Introduction:
The foreign policy of the United States reflects its role as one of the world's most powerful and influential
nations. Over the decades, American foreign policy has evolved from isolationism to a position of global
leadership. Its primary goals include protecting national interests, promoting democracy, ensuring
economic growth, and maintaining international peace. Both historical events and current global
challenges shape U.S. foreign policy.
