What is NATO?

• A. European Union
• B. NATO
• C. Warsaw Pact
• D. Organization of American States

Answer: (B)

NATO is a military alliance of North American and European nations that commit to mutual defense if one member is attacked. It began in 1949 with the North Atlantic Treaty to deter aggression in the early Cold War and to maintain security through collective defense. The core idea is that an attack on one member is considered an attack on all, which enables shared planning, resources, and a unified response. Over time, NATO has also taken on crisis management and cooperative security roles, adapting to evolving threats. The other options don’t fit because the European Union is mainly an economic and political union, the Warsaw Pact was a Soviet-led defense bloc that dissolved in 1991, and the Organization of American States focuses on political, economic, and social issues in the Americas rather than mutual defense.
