How did the league of Nations fail in protecting countries from invasion?

Answer 1

The League of Nations failed to protect countries from invasion primarily due to its lack of enforcement power and the absence of major powers like the United States. Its decisions relied on collective security and economic sanctions, which were often ineffective and lacked the necessary military backing. Additionally, member nations prioritized their national interests over collective action, leading to inaction during crises, such as the Japanese invasion of Manchuria and the Italian invasion of Ethiopia. This inability to respond decisively undermined its credibility and ultimately contributed to its collapse.
