Collective security

Definition

Collective security is a system in which states agree to take joint action to prevent or respond to aggression against any member of the group. This concept relies on the belief that an attack against one member is considered an attack against all, fostering cooperation among nations to maintain peace and stability. It is closely tied to the establishment of international organizations aimed at promoting peace and diplomacy following conflicts, particularly in the context of global tensions during and after World War I.

Review Questions

• How did collective security influence the political landscape following World War I?
  • Collective security significantly shaped the post-World War I political landscape by promoting the idea that countries should work together to prevent future conflicts. This notion was embedded in Wilson's Fourteen Points and became a foundational principle for the League of Nations. However, despite these ideals, the League struggled to enforce collective security due to lack of commitment from major powers and conflicting national interests among member states.
• Evaluate the effectiveness of the League of Nations in implementing collective security during its existence.
  • The League of Nations faced numerous challenges in effectively implementing collective security. While it was designed to facilitate cooperation and prevent aggression through collective action, its inability to enforce decisions weakened its authority. Notably, instances such as the invasion of Manchuria by Japan and Italy's invasion of Ethiopia illustrated the League's shortcomings in rallying member states to act decisively against aggression, ultimately leading to its diminished influence by the 1930s.
