The United States considered the Treaty of Versailles but ultimately did not ratify it. The U.S. Senate voted against joining the treaty and joining the League of Nations, which was a key component of the treaty. This decision was primarily influenced by a combination of factors, including concerns about compromising U.S. sovereignty, opposition from conservative senators, domestic political pressures, and a desire to avoid future international conflicts. As a result, the United States did not become a member of the League of Nations and pursued a policy of isolationism for much of the 1920s and 1930s.
