World War I and America

World War I, which lasted from 1914 to 1918, marked a significant turning point for the United States in terms of foreign policy and military engagement. Initially, America maintained a policy of neutrality, reflecting its isolationist tendencies; however, various factors, such as unrestricted submarine warfare and the Zimmermann Telegram, compelled the nation to enter the war in 1917. The involvement of American troops and resources bolstered the Allies, ultimately leading to a decisive victory. The war's conclusion brought about the Treaty of Versailles, which not only redrew the map of Europe but also sowed the seeds for future conflict, influencing American politics and society in the subsequent decades.
