In a paragraph, analyze how the outcome of World War I shaped the United States' role as an international leader.

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. On the home front, millions of women went to work, replacing the men who had shipped off to war, while others knitted socks and made bandages. For African-American soldiers, the war opened up a world not bound by America’s formal and informal racial codes.
