Answer:
The Zimmermann Telegram helped turn the U.S. public, already angered by repeated German attacks on U.S. ships, firmly against Germany. On April 2, President Wilson, who had initially sought a peaceful resolution to World War I, urged immediate U.S. entrance into the war.
Explanation:
On February 24, 1917, British authorities gave Walter Hines Page, the U.S. ambassador to Britain, a copy of the Zimmermann Telegram, a coded message from Zimmermann to Count Johann von Bernstorff, the German ambassador to Mexico. In the telegram, intercepted and deciphered by British intelligence in late January, Zimmermann instructed his ambassador, in the event of a German war with the United States, to offer significant financial aid to Mexico if it agreed to enter the conflict as a German ally. Germany also promised to restore to Mexico the lost territories of Texas, New Mexico, and Arizona.
