There are several reasons the U.S. did not ratify the Treaty of Versailles. First of all, as was already stated, the people of the United States were disillusioned. They had been told that they were the "good guys" and that this was going to be a "war to end all wars." However, as the war ended and the images became clear, people realised that this war was not a pretty affair, and they wanted nothing to do with it.. Secondly, many people in the U.S. were wary of Wilson's League of Nations (a precursor to the United Nations of today). It violated George Washington's farewell address which stated that the United States should avoid entangling alliances and should stay out of European affairs as much as possible.. The third, and one of the greatest reasons, which is often overlooked, requires the examination of Henry Cabot Lodge, the Chairman of the Senate Foreign Relations Committee. Pres. Woodrow Wilson and Lodge were bitter enemies. Thus, when Wilson went to France to discuss peace, he did not take Lodge with him. So, when Wilson called for the ratification of the Treaty of Versailles and of his Fourteen Points, he needed the backing of Henry Cabot Lodge because of his position on the Foreign Relations Committee. However, he did not get Lodge's support since he failed to take him to France. Consequently, Wilson toured the United States trying to raise support for the League of Nations and the Treaty of Versailles, but at the same time, Lodge and the Republicans were following his campaign trail, stating the opposite. Wilson's health failed, and the Treaty of Versailles failed to get ratified. Consequently, the United States entered into a period of isolation, leading to the rise of Japan and Germany into WWII.
