Didnt the USA get into WW2 also because a letter was sent to Mexico promising a section of the USA to them and the letter was read by the USA. I think the name of the letter started with a T. HELP?

Answer 1

You are thinking of the First World War, not the Second. It was called the Zimmermann Note or Telegram.

This was a telegram from the German Foreign Minister, Arthur Zimmermann, to his ambassador in Mexico, containing details of a proposed alliance against America; it was intercepted and published, strengthening US public support for war against Germany in the Great War (WW One). It was sent January 19, 1917. It was intercepted (read) by British Intelligence, passed to the US Government in February, and released to the press on March 21, 1917.

Full text of The Zimmermann Telegram (translated from German): "On the first of February we intend to begin submarine warfare unrestricted. In spite of this, it is our intention to endeavor to keep neutral the United States of America. If this attempt is not successful, we propose an alliance on the following basis with Mexico: That we shall 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. Zimmerman" (Sent January 19, 1917)
