Final answer:
The weakening and collapse of the League of Nations can be attributed to the lack of military power, ineffectiveness in halting aggression, and lack of participation by key countries.
Step-by-step explanation:
The weakening and collapse of the League of Nations were contributed by several factors:
- Lack of military power: The League did not have its own military force and therefore relied on member states to provide military support. This limited its ability to enforce its decisions and deter acts of aggression.
- Ineffectiveness in halting aggression: The League was often ineffective in stopping acts of aggression by larger countries because of its lack of authority and the unwillingness of some nations to impose economic sanctions or take military action.
- Lack of participation: Several powerful countries, such as Germany, Russia, and the United States, were not initially included in the League, which weakened its global influence and ability to address international conflicts.
