The primary purpose of the Zimmermann Telegram was to ally with Mexico against the United States. Sent by German foreign minister Arthur Zimmermann in January 1917, the telegram proposed a military alliance between Germany and Mexico in the event that the United States entered World War I. Germany promised to support Mexico in regaining territories lost to the U.S., such as Texas, New Mexico, and Arizona. This communication aimed to distract the U.S. by opening another front in North America while Germany sought to continue its military campaigns in Europe.

The significance of the telegram lies in its role as a catalyst for U.S. public opinion, which shifted dramatically against Germany after its interception and the subsequent publication. The other choices do not accurately reflect the intent of the telegram, as it was specifically focused on a strategic military alliance rather than peace proposals, arms negotiations, or declarations of war directed at Russia.
