Which policy aimed to contain Soviet expansion by providing aid to Greece and Turkey?

• A. Marshall Plan
• B. National Security Act
• C. Eisenhower Doctrine
• D. Truman Doctrine

Answer: (D)

The idea being tested is containment through targeted aid to vulnerable allies. The Truman Doctrine declared that the United States would support free peoples resisting subjugation by armed minorities or outside pressures, starting with aid to Greece and Turkey to prevent their fall to Soviet influence. This established a clear, proactive stance of American involvement to halt the spread of communism in strategically important regions, shaping Cold War policy for years to come. The Marshall Plan, while also aiming to curb communist appeal by stabilizing economies, focused on rebuilding Western Europe as a whole rather than specifically aiding Greece and Turkey. The National Security Act reorganized the U.S. military and intelligence framework, not a policy aimed at a particular country. The Eisenhower Doctrine later expanded containment to the Middle East, but it is not the policy that focused on Greece and Turkey.
