Why did the Zimmerman Telegram push the US toward World War 1?
The United States had to declare War on Germany and its allies because of what the telegram had from Arthur Zimmermann, the minister of Germany, to Von Eckhardt, the minster of Mexico, that if Mexico were to join Alliances they would help Mexico get back what The United States took from them during the Mexican-American War. The States that The Untied States Won From Mexico were Texas, New Mexico, and Arizona.
