Both the Korean War and the Vietnam War are examples of U.S. efforts to apply which policy?

• A. Detente
• B. Isolationism
• C. Alliance building
• D. Containment policy

Answer: (D)

Containment focuses on stopping the spread of communism by preventing it from expanding into new areas. The Korean War and the Vietnam War were driven by the United States’ aim to keep communism from gaining in these regions and potentially spreading to neighboring countries. In Korea, the U.S.-led effort backed South Korea to repel the North’s invasion and preserve a non-communist government on the peninsula. In Vietnam, the goal was to prevent a communist takeover of South Vietnam and halt a broader regional spread. Detente emphasizes easing tensions, isolationism avoids entanglement, and alliance-building isn’t the central aim here; containment is.
