How was the United States of America brought into world Politics

The United States initially maintained an isolationist foreign policy, primarily focused on its own continent. Its emergence onto the world stage began with the Spanish-American War in 1898, which led to overseas territorial acquisitions. However, it was the two World Wars that decisively brought the U.S. into global politics, particularly World War II, after which it became a leading superpower and played a central role in establishing international organizations and shaping the post-war world order.
