What theory held that the United States should stop the spread of communism through force?

• A. Détente
• B. Containment
• C. Truman Doctrine
• D. Isolationism

Answer: (B)

This question tests understanding of containment—the strategy the United States used to stop the spread of communism by resisting Soviet influence and preventing further expansion, often employing military means when necessary. Containment grew from early Cold War thinking that the danger was not just in one country but in how far communism could spread, so the U.S. pledged to block its growth, supported by actions like military alliances and, when required, force to halt advances. Détente aimed to reduce tensions with the Soviet Union, not to halt expansion through force. Isolationism seeks to withdraw from international conflicts, not confront them abroad. The Truman Doctrine is a specific policy within containment that promised aid to countries resisting communism; while related, it describes a particular measure rather than the broader approach of containment itself.
