USA HISTORY

Detailed explanation-1: -This telegram, written by German Foreign Secretary Arthur Zimmermann, is a coded message sent to Mexico, proposing a military alliance against the United States.

Detailed explanation-2: -The note revealed a plan to renew unrestricted submarine warfare and to form an alliance with Mexico and Japan if the United States declared war on Germany. The message was intercepted by the British and passed on to the United States; its publication caused outrage and contributed to the U.S. entry into World War I.

Detailed explanation-3: -Several weeks later, on February 24, the British presented the Zimmermann telegram to the U.S. Government in an effort to capitalize on growing anti-German sentiment in the United States. The American press published news of the telegram on March 1.

Detailed explanation-4: -Zimmermann’s alliance proposal did reach the desk of Mexican President Carranza, but it was officially rejected once a military commission determined that there would be no benefit in accepting it.
