How did the American public react when the Zimmermann message was made public?

The American public reacted with nationalist anger against Germany when the Zimmermann message was made public. The Zimmermann Telegram, a secret communication sent by Germany to Mexico, proposed a military alliance between the two countries should the United States enter World War I. Upon its release, many Americans were outraged not only by Germany's attempt to incite conflict with the U.S. but also by the implications of a foreign power attempting to influence their neighbors against them. This incident heightened public sentiment in favor of entering the war and contributed to the growing desire to support the Allies in their fight against the Central Powers. Nationalist feelings were galvanized as people rallied around the idea of defending their nation and preventing German aggression.
