What was the primary purpose of the NATO alliance formed in 1949?

• A. Mutual defense against aggression
• B. Promote global trade
• C. Regulate international shipping
• D. Coordinate space exploration

Answer: (A)

The idea being tested is how allies use collective defense to deter aggression. NATO formed in 1949 to provide mutual protection against attack, especially in the face of the Soviet Union’s power after World War II. The key feature is that an armed attack on any one member would be considered an attack on all, so the alliance could respond together. This created a strong deterrent: potential aggressors would know they’d face a united military response, not just one country.

This focus on defense and deterrence is why the primary purpose isn’t to promote global trade, regulate shipping, or coordinate space exploration. Those areas belong to other organizations and programs, while NATO’s purpose centers on security and collective defense.
