Which document outlines the principles of U.S. foreign policy concerning opposition to European colonization in the Americas?

The Monroe Doctrine is the document that articulates the principles guiding U.S. foreign policy in relation to European colonization in the Americas. Issued in 1823, it declared that any further European intervention in the political affairs of the nations of the Americas would be viewed as an act of aggression against the United States. In this way, the Monroe Doctrine aimed to protect the sovereignty of newly independent nations in Latin America and to discourage European powers from expanding their influence in the region.

This policy has been significant in shaping U.S. diplomatic relations and reflects the nation's intent to assert its sphere of influence in the Western Hemisphere, establishing a clear boundary against European colonialism. The importance of the Monroe Doctrine in the historical context of U.S. foreign policy cannot be overstated, as it laid the groundwork for subsequent American engagement and intervention in Latin American affairs.

Other choices, while important in their own contexts, do not specifically address the issue of European colonization in the Americas. The Truman Doctrine primarily focused on containing communism during the Cold War, the Bretton Woods Agreement dealt with international economic cooperation after World War II, and the Treaty of Paris refers to various treaties that ended wars and established peace but did not specifically outline a stance against European colonization
