What was one effect of the Spanish-American War on American foreign policy?

The Spanish-American War marked a significant turning point in American foreign policy, primarily leading to increased military involvement in both Asia and Latin America. Following the victory over Spain in 1898, the United States emerged as a global power, acquiring territories such as Puerto Rico, Guam, and the Philippines. This expansion allowed the U.S. to establish a stronger military presence in these regions and assert its influence in world affairs.

The war also prompted a shift from a largely isolated stance to one where the U.S. became actively engaged in international conflicts and expansionist policies, particularly as the nation sought new markets for its goods and to assert itself against European powers. The subsequent interventions in Cuba, the Philippines, and the construction of the Panama Canal further underscored the U.S.'s commitment to a robust presence in both Latin America and Asia. This period laid the groundwork for future American imperialism, clearly highlighting the shift toward increased military involvement as a primary effect of the Spanish-American War.
