Which organization is a political and military alliance formed for defense by Canada, the U.S., and Western Europe?

• A. European Union
• B. African Union
• C. Arab League
• D. North Atlantic Treaty Organization

Answer: (D)

Collective security through a formal defense alliance. NATO, the North Atlantic Treaty Organization, is a political and military alliance created to defend its member countries in North America and Europe. It formed after World War II to deter aggression, particularly from the Soviet Union, and it operates on the idea that an attack on one member is an attack on all, prompting a coordinated defense response. Members include Canada, the United States, and many Western European nations, binding them to joint planning and military support. The other organizations listed serve different purposes: the European Union focuses mainly on economic and political integration, the African Union aims at unity and development across Africa, and the Arab League coordinates among Arab states but does not function as a single mutual-defense treaty like NATO. NATO best fits the description.
