in a short paragraph What was the role of the us in WWQ and the writing of the Treaty of Versailles

During World War I, the United States initially maintained a policy of isolationism. However, repeated attacks on American ships by German submarines compelled the U.S. to enter the war in 1917 on the side of the Allies (Britain, France, and Russia). The U.S. provided fresh troops and supplies, which significantly contributed to the Allied victory. At the end of the war, U.S. President Woodrow Wilson played a key role in drafting the Treaty of Versailles. He proposed the "Fourteen Points" which emphasized the importance of self-determination, freedom of the seas, and a league of nations to maintain peace. However, many of Wilson's ideas were not included in the final treaty, which imposed heavy penalties on Germany. The U.S. Senate ultimately rejected the Treaty of Versailles, partly due to concerns about the League of Nations infringing on U.S. sovereignty.
