Read the excerpt from the Zimmermann Telegram sent from Germany to Mexico in 1917. 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. What can be concluded from the excerpt about how the telegram contributed to US entry into World War I? The United States felt betrayed by Mexico. Germany’s request for money angered the United States. Germany’s offer of land posed a direct threat to the United States. The United States wanted to support Mexico in its conflict with Germany.
