How did the zimmeman telegram influence the US entry to world war 1?

The Zimmerman Telegram significantly influenced the U.S. entry into World War I by revealing Germany's attempt to incite Mexico to join the war against the United States. In the telegram, Germany promised Mexico the territories of Texas, New Mexico, and Arizona in exchange for their support. The interception and publication of this secret communication outraged the American public and heightened anti-German sentiment. This, combined with Germany's unrestricted submarine warfare, ultimately swayed public opinion and contributed to the U.S. declaring war on Germany in April 1917.
