Which multinational alliance originated during the Cold War to promote collective security among member countries?

• A. European Union
• B. NATO; North Atlantic Treaty Organization
• C. Commonwealth of Nations
• D. Shanghai Cooperation Organization

Answer: (B)

The concept being tested is the idea of collective security through a military alliance formed during the early Cold War. The alliance that began in 1949 united the United States, Canada, and many Western European nations to deter aggression by promising mutual defense: if one member was attacked, all pledged to come to its aid. This formal commitment to defend each other in the face of a common threat is the hallmark of the alliance’s purpose and why it fits the question so well. Its creation was specifically tied to countering the Soviet Union and maintaining a balance of power in Europe, which is exactly what “promote collective security among member countries” during that era describes. The other groups are not a fit for this specific origin and purpose. The European Union focuses mainly on economic and political integration, not a Cold War–era military defense pact. The Commonwealth of Nations is a loose association of former colonies with cultural and political ties, lacking a formal mutual defense commitment. The Shanghai Cooperation Organization is a more recent regional framework focused on security and cooperation in Eurasia, not a product of the Cold War era.
