Final answer:
The League of Nations tried to keep the peace through enforcing treaties, facilitating negotiations, and providing a platform for international diplomacy. However, it failed due to its lack of enforcement power, inability to prevent aggressive actions, and weaknesses within the organization.
Step-by-step explanation:
The League of Nations tried to keep the peace through enforcing treaties, facilitating negotiations, and providing a platform for international diplomacy. It did not have a powerful military to deter aggression, and it did not promote isolationism among nations. It also did not impose economic sanctions on all nations.
The League of Nations failed at keeping the peace due to its lack of enforcement power, inability to prevent aggressive actions, the absence of the United States, and general weaknesses within the organization. It did not succeed in preventing all conflicts, and it did not have too much power and control. It did have a role in global politics, but it was largely ineffective in preventing conflicts between nations.
