If the United States had joined the League of Nations, it could have maintained peace and stability, influenced decisions, and prevented the rise of totalitarian regimes and World War II.
Step-by-step explanation:
If the United States had ratified the Treaty of Versailles and joined the League of Nations after helping the allies win the Great War, it would have had a significant impact on the world stage. Firstly, the United States would have played a crucial role in maintaining peace and stability, as the League of Nations aimed to prevent future conflicts. The United States could have used its economic and military power to influence decisions, such as imposing sanctions on aggressive countries. Additionally, the United States' participation could have led to a more balanced distribution of power among nations, reducing the grievances that ultimately led to the rise of totalitarian regimes and World War II.
