in the zimmmgramns telgram, what did zimmmerman promise mexico if they would ally with gerymany against usa?

In the Zimmermann Telegram, which was sent by German Foreign Minister Arthur Zimmermann to the German ambassador in Mexico in January 1917, Germany promised to support Mexico in regaining territories it had lost to the United States. Specifically, Germany proposed that if Mexico allied with Germany against the U.S., they would help Mexico recover Texas, New Mexico, and Arizona. The telegram was intercepted and decoded by British intelligence and eventually leaked to the United States, contributing to the American public's support for entering World War I against Germany.
