1. America enters WWI

2. 1914-1917 For the first 3+ years of World War One, The United States had officially remained neutral. Neutral = not helping or supporting either side; impartial. Most Americans did not want the United States to enter WWI. They felt it was a European problem/ not our fight. Many Americans had sympathies for both sides, making it difficult to support one over the other. America has a long history with Britain and France There were millions of German immigrants living in the U. S. America was able to stay out of the fighting, but still trade with all sides. America can make a lot of money as long as they stay neutral

5. The “Zimmerman Telegram” In 1917 the British intercepted a telegram sent from Germany to Mexico. Germany was getting worried that the U.S. might enter WWI and support England/France Germany offered Mexico an alliance if they would agree to wage war on the United States. Germany promised money, and the return of Texas, New Mexico, and Arizona to Mexico if they helped Germany win WWI. Americans were outraged
