ZIMMERMANN TELGRAM (1917)
We intend to begin on the first of February submarine warfare unrestricted. In spite of this, it is our intention to endeavor to keep neutral the United States of America.
In the event of this not succeeding, we make Mexico a proposal of alliance on the following: make war together and together make peace. We shall give general financial support, and it is understood that Mexico is to reconquer the lost territory in New Mexico, Texas, and Arizona. The details are left to you for settlement
You are instructed to inform the President of Mexico of the above in the greatest confidence as soon as it is certain that there will be an outbreak of war with the United States and suggest that the President of Mexico, on his own initiative, should communicate with Japan suggesting adherence at once to this plan; at the same time, offer to mediate between Germany and Japan.
Please call to the attention of the President of Mexico that the employment of ruthless submarine warfare now promises to compel England to make peace in a few months.
Alfred Zimmermann, German Foreign Minister
