Which military alliance was created in 1949 to coordinate defense among Western nations?

• A. United Nations
• B. SEATO
• C. NATO
• D. Warsaw Pact

Answer: (C)

Coordinated defense among Western nations after World War II. In 1949, Western countries formed the North Atlantic Treaty Organization to coordinate defense and security, with the idea that an attack on one member would be treated as an attack on all. This collective-security approach helped deter aggression during the early Cold War and tied the United States, Canada, and Western European nations into a formal military alliance.

Other options don’t fit the details. The United Nations, established in 1945, is a global peacekeeping body rather than a regional military alliance for Western defense. SEATO, created in 1954, addressed Southeast Asia, not Western defense or the 1949 timeframe. The Warsaw Pact, formed in 1955, was a Soviet-led alliance acting as a counterpart to NATO, not an alliance among Western nations.
