Which policy established the idea of containing communism by providing aid to nations resisting communism, particularly in Europe?

• A. Truman Doctrine
• B. Eisenhower Doctrine
• C. Monroe Doctrine
• D. Marshall Plan

Answer: (A)

The main idea here is containment: using aid to help nations resist the spread of communism. The Truman Doctrine did exactly that when it was announced in 1947. It stated that the United States would provide political, military, and economic support to free peoples who were resisting subjugation by armed minorities or outside pressures. In Europe, this meant backing governments and movements opposed to communist influence, signaling a shift in U.S. policy toward actively containing Soviet influence rather than staying aloof. This approach helped frame later actions, including guiding U.S. aid to Greece and Turkey and setting a precedent that economic assistance could be a frontline tool in preventing the spread of communism. By contrast, the Marshall Plan focused on rebuilding Western Europe’s economies to reduce the appeal of communism, which is related but not the same explicit policy of containment through aid to resisting nations. The Eisenhower Doctrine extended a similar logic to the Middle East, while the Monroe Doctrine concerns opposing European intervention in the Americas and predates the Cold War.
