How did the end of World War One affect Americans

The entry of the United States into World War I changed the course of the war, and the war, in turn, changed America. ... The American Expeditionary Forces arrived in Europe in 1917 and helped turn the tide in favor of Britain and France, leading to an Allied victory over Germany and Austria in November 1918.

by the time of the armistice, more than four million Americans had served in the armed forces and 116,708 had lost their lives. The war shaped the writings of Ernest Hemingway and John Dos Passos. It helped forge the military careers of Dwight D. Eisenhower, George S. Patton, and George C. Marshall.
