Which organization is correctly matched with its purpose to deter Soviet expansion in Europe?

• A. SEATO
• B. ANZUS
• C. NATO
• D. Warsaw Pact

Answer: (C)

Deterrence through a formal, collective defense commitment is what this question is getting at. NATO was created in 1949 to prevent the Soviet Union from expanding its influence into Western Europe by binding member states to defend one another. The idea is that the threat of a united, credible response—military, political, and later nuclear assurances—would deter aggression before it happens. That makes NATO the best fit for the purpose of deterring Soviet expansion in Europe. SEATO focused on Southeast Asia, not Europe. ANZUS is a Pacific security pact among the US, Australia, and New Zealand, again outside Europe. The Warsaw Pact was a Soviet-led alliance meant to counter NATO and secure the Eastern Bloc, reinforcing Soviet control rather than serving as the instrument to deter Soviet expansion into Europe.
