March 1, 1917: The Zimmerman Telegram Story Breaks

On February 20, 1917 British intelligence revealed to the US ambassador to Great Britain the contents of the Zimmerman telegram, go here to read about the telegram.  The Brits disclosed to the Americans the code breaking that they engaged in to read the message.  When the telegram was disclosed to the public, in order to protect British code breaking, it was alleged that British agents had stolen a copy of the telegram in Mexico.  The contents of the message was so fantastic that many Americans thought it was likely a fake produced by the British, which was the line taken by the mighty Hearst empire.  President Wilson was  faced with a dilemma as to whether to disclose that the British had decoded the message, and risk the ability of the British to read German messages, or to let the erroneous charges that the telegram was a fake remain unanswered. His dilemma would be shortly resolved by an unlikely source.

January 11, 1917: Zimmermann Telegram Sent

 

I assume that there must be a greater example of diplomatic folly than the Zimmermann Telegram, but I cannot think of it at the moment.  Believing that the entry of the US into the Great War was inevitable with the planned resumption by Germany of unrestricted submarine warfare against neutral shipping, the German Foreign Secretary Arthur Zimmermann on January 11, 1917 sent the following telegram in code to the German ambassador to Mexico Heinrich von Eckardt:

“We intend to begin on the first of February unrestricted submarine warfare. We shall endeavor in spite of this to keep the United States of America neutral. In the event of this not succeeding, we make Mexico a proposal of alliance on the following basis: make war together, make peace together, generous financial support and an understanding on our part that Mexico is to reconquer the lost territory in Texas, New Mexico, and Arizona. The settlement in detail is left to you. You will inform the President of the above most secretly as soon as the outbreak of war with the United States of America is certain and add the suggestion that he should, on his own initiative, invite Japan to immediate adherence and at the same time mediate between Japan and ourselves. Please call the President’s attention to the fact that the ruthless employment of our submarines now offers the prospect of compelling England in a few months to make peace.” Signed, ZIMMERMANN

The sheer madness of this cannot be overstated.  Mexico was still in the throes of the Mexican Revolution and posed no threat to the US.  The US had recently demonstrated that it could dispatch military forces into Mexico with impunity.  Threatening the physical integrity of the US converted a far off European conflict into a direct threat against the US.  If the US did intervene in the Great War, an additional conflict with Mexico would barely resister in regard to the immense military mobilization that the US would undergo.
