Explanation:

The Treaty of Versailles was a post - World War I treaty. Congressional leaders in the U.S. were isolationist. They feared that U.S. soldiers being used to fight more overseas wars (as part of the League of Nations, which was related to the Treaty of Versailles) would draw the U.S. into unnecessary foreign entanglements. This was a key reason for the U.S. not ratifying the Treaty of Versailles.
