Wow just wow look do some research before you make statement like this, for the record, it's called the Zimmermann Telegram,
On the first of February, we intend to begin unrestricted submarine warfare. In spite of this, it is our intention to endeavor to keep the United States of America neutral. In the event of this not succeeding, we propose an alliance on the following basis with Mexico: That we shall make war together and make peace together. We shall give generous financial support, and an understanding on our part that Mexico is to reconquer the lost territory in New Mexico, Texas, and Arizona. The details of settlement are left to you. 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, on his own initiative, invite Japan to immediate adherence with this plan; at the same time, offer to mediate between Japan and ourselves. Please call to the attention of the President that the ruthless employment of our submarines now offers the prospect of compelling England to make peace in a few months.
The Zimmermann Telegram was a coded telegram said to have been dispatched by the Foreign Secretary of the German Empire, Arthur Zimmermann, on January 16, 1917, to the German ambassador in Washington, Johann von Bernstorff, at the height of World War I. On January 19, Bernstorff, per Zimmermann's request, forwarded the Telegram to the German ambassador in Mexico, Heinrich von Eckardt. Zimmermann sent the Telegram in anticipation of the resumption of unrestricted submarine warfare by the German Empire on February 1, an act which German High Command feared would draw the neutral United States into war on the side of the Allies. The Telegram instructed Ambassador Eckardt that if the United States appeared likely to enter the war he was to approach the Mexican government with a proposal for military alliance. He was to offer Mexico material aid in the reclamation of territory lost during the Mexican-American War, specifically the American states of Texas, New Mexico, and Arizona. Eckardt was also instructed to urge Mexico to help broker an alliance between Germany and Japan.
