WW1 - Germany Asks Mexico To Join the Fight Against the USA

World War I - Wikipedia, the free encyclopedia

In January 1917, Germany resumed unrestricted submarine warfare. The German Foreign minister, in the Zimmermann Telegram, told Mexico that U.S. entry was likely once unrestricted submarine warfare began, and invited Mexico to join the war as Germany's ally against the United States. In return, the Germans would send Mexico money and help it recover the territories of Texas, New Mexico, and Arizona that Mexico lost during the Mexican-American War 70 years earlier.^[99] Wilson released the Zimmerman note to the public and Americans saw it as a casus belli—a cause for war.
