What effect did the us have after U. S. senate does not ratify the Treaty of Versailles of join the League of Nations

The Treaty as you can imagine received enormous opposition. Henry Cabot Lodge and Alfred Beveridge strongly denounced the treaty, especially Article Ten which called upon the US to support League actions. Wilson campaigned vigorously and gave 37 speeches in 29 cities in a span of only three weeks. He declared that US soldiers should not have died in vain. After a dramatic speech in Colorado Wilson collapsed. His health had been poor for sic months and the strain of the trip was too much. He was rushed back to Washington and a few days later had a massive stroke. For the next year and a half he was incapable of running the government but was protected by his wife and closest advisors.

1. In March 1920 the US Senate finally killed the treaty. The United States did not ratify the Treaty of Versailles and we did not join the League of Nations. Wilson considered this a great failure and it plagued him until his death.
