The United States joined World War I on April 6, 1917, after a long period of neutrality. The decision to enter the war was influenced by several factors, including unrestricted submarine warfare by Germany and the interception of the Zimmermann Telegram, which proposed a military alliance between Germany and Mexico against the U.S. The U.S. mobilization of troops and resources significantly bolstered the Allied Powers in their fight against the Central Powers.
