Which international organization was created after WWI to prevent future wars but lacked enforcement power and did not include the US?

• A. League of Nations
• B. United Nations
• C. NATO
• D. Warsaw Pact

Answer: (A)

Post‑World War I, nations created the League of Nations to prevent another devastating war, but its power to enforce decisions was weak because it had no real military force of its own and relied on member cooperation. A crucial factor is that the United States never joined, which significantly weakened the organization’s authority and legitimacy. Without a built‑in way to compel behavior or to sanction aggressors, it struggled to stop violations or to deter aggression, and it ultimately failed to prevent the conflicts that led to World War II. After the war, a new international body—the United Nations—was created with more robust mechanisms for enforcement. NATO and the Warsaw Pact are Cold War military alliances, formed later to address security concerns in a different era.
