Which postwar organization exemplified the move toward international cooperation and collective security?

• A. The Axis Council
• B. The Warsaw Pact
• C. The North Atlantic Treaty Organization
• D. The League of Nations

Answer: (D)

International cooperation and collective security after a major war aim to prevent future conflict by having nations work together through a formal international framework. The League of Nations was created after World War I to provide just that: a permanent forum where states could discuss disputes, negotiate peacefully, and respond to aggression with collective measures such as sanctions or diplomacy rather than one country acting alone. It embodied the idea that security was a shared responsibility—the threat to one was a threat to all—and it sought to resolve disputes through dialogue and cooperation on a global scale. Although it struggled—major powers sometimes refused to participate or violated its principles, and it ultimately could not stop aggression in the 1930s—it stands as the clearest early illustration of moving toward organized, multilateral efforts to maintain peace. By contrast, the other options reflect different patterns of postwar power dynamics: blocs or military alliances tied to specific regions or rival camps rather than a universal cooperative framework aimed at collective security.
