Question

The League of Nations was not included in the final treaty.
The League of Nations was created, but the U.S. did not join
The U.S. was the first to join the League of Nations
The U.S. joined the League of Nations after ratifying the treaty

Answer 1

The correct result of Woodrow Wilson’s proposal to create a League of Nations at the Treaty of Versailles is:

The League of Nations was created, but the U.S. did not join.

Although the League of Nations was established as part of the Treaty of Versailles in 1919, the U.S. Senate did not ratify the treaty, and therefore the United States did not become a member of the League.
