Which alliance was created in 1949 to counter Soviet influence in Europe?

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

Answer: (A)

After World War II, Western leaders sought a unified security commitment to deter Soviet expansion in Europe. The alliance created in 1949 is NATO, the North Atlantic Treaty Organization, formed to bind the United States, Canada, and Western European nations into a collective defense pact. The key idea is that an attack on one member is treated as an attack on all, creating a strong deterrent through united military strength and signaling that Western Europe would not face aggression alone. This approach aimed to preserve peace in the region by making potential aggressors know the cost of crossing the alliance would be too high. SEATO was created in the 1950s for Southeast Asia, not Europe; the OAS operates in the Americas; and the Warsaw Pact began in 1955 as a Soviet-led counterpart to NATO, not a 1949 formation.
