Write a paragraph in which you explain how nationalism contributed to the United States entering World War 1.

Nationalism played a significant role in the United States' entry into World War I. As the war unfolded in Europe, a strong sense of nationalism emerged among Americans, fueled by a desire to protect democratic principles and uphold national honor. The sinking of the British ocean liner Lusitania by a German submarine in 1915, resulting in the loss of American lives, heightened anti-German sentiments and contributed to a growing fervor for intervention. Additionally, the interception of the Zimmermann Telegram in 1917, where Germany proposed a military alliance with Mexico against the United States, further fueled patriotic outrage. These events, combined with a sense of duty to support their allies and preserve democratic values, ultimately swayed public opinion, leading to the U.S. declaration of war against Germany on April 2, 1917. Nationalism served as a powerful force driving the nation's commitment to the war effort and its eventual involvement in World War I.
