The United States entered World War One out of 1917 and the nation was paralyzed , by the butcher that occurred in what was intended to be an enlightened piece of the world. In the psyches of a considerable lot of the nations that partook in the war, the best way to keep away from reiteration of a different universe War, was to make a worldwide body whose reason for existing was to fix any global debate and to keep up a world harmony, or at any rate European harmony. This worldwide body before long turned into the League of Nations, which was bolstered as a characterizing factor in world harmony by countries of the world. In any case, the United States played out the demonstration of noninterference rather than including themselves in world issues, which prompted America dismissing the chance to join the League of Nations. In this paper I will talk about the inquiry "For what reason did the United States won't join the League of Nations?" by taking a gander at the reasons why the United States decided not to join, just as breaking down if this was the right move by the Americans. I will take a gander at Woodrow Wilson's "Fourteen Points" and how it was gotten among European and American pioneers, just as why the United States wouldn't join the alliance of Nations and why they effectively made progress toward the outside arrangement of Isolationism. This will be finished with examination of the Fourteen Points and the investigation of the "Hotel Reservations". The United States not joining the League of Nations was essential as America was viewed as a standout amongst the most dominant countries on the planet, and without the United States the League of Nations was bound to not be as solid as it could be without American help. Woodrow Wilson gave a discourse to congress that would recently be known as the "Fourteen Points", which was a discourse that Wilson viewed as the main conceivable reason for suffering world harmony and the premise of the possibility of the League of Nations. In the discourse, Wilson tended to what he accepted to be the reasons for the First World War by requiring the abrogation of mystery arrangements, the change of pilgrim asserts, a decrease of combat hardware, and the opportunity of the oceans. Wilson would then guarantee to evacuate any monetary boundaries among countries, and the making of a world association that would ensure political autonomy, which would later turn into the League of Nations.
