Answer :
As the war drew to a close, Woodrow Wilson set forth his plan for a "JUST PEACE." Wilson believed that fundamental flaws in international relations created an unhealthy climate that led inexorably to the World War.
Americans were also uneasy about Wilson's scheme for a League of Nations. They were concerned that belonging to the League would drag the USA into international disputes that were not their concern. In the end, the Congress rejected the Treaty of Versailles and the League of Nations.
