Answer the prompt using complete sentences in paragraph form. Why did the US end its neutrality after WWI had been going on for almost three years? __

The United States abandoned its policy of neutrality during World War I for several reasons. One significant factor was the increasing threat posed by German unrestricted submarine warfare, which targeted American and other neutral nations' ships. The sinking of the British ocean liner Lusitania in 1915, resulting in the loss of American lives, heightened tensions. Additionally, the interception of the Zimmermann Telegram in 1917, where Germany proposed a military alliance with Mexico against the United States, further fueled anti-German sentiment. These events, coupled with economic interests and a desire to shape the post-war world order, led the U.S. to abandon its neutrality and officially enter the war on the side of the Allies in April 1917. The decision marked a turning point in the conflict and significantly influenced its eventual outcome.
