Review Questions

• How did the Zimmermann Telegram contribute to the shift in American public opinion regarding entry into World War I?
  • The Zimmermann Telegram played a significant role in shifting American public opinion toward supporting entry into World War I by revealing Germany's intentions to undermine U.S. sovereignty through a potential alliance with Mexico. When it became public knowledge that Germany was encouraging another nation to wage war against the U.S., it sparked outrage among Americans, leading many to view Germany as a direct threat. This outrage, combined with other factors such as Germany's unrestricted submarine warfare, made it increasingly difficult for the U.S. government to remain neutral.

  • The Zimmermann Telegram had significant implications for U.S.-Mexico relations as it placed Mexico in a precarious position. Although Mexico ultimately did not accept Germany's proposal for an alliance due to various reasons including internal issues and U.S. military strength, the telegram created mistrust between Mexico and the United States. The event heightened tensions and highlighted Mexico's vulnerability during a time when it was also dealing with its own revolution.
