What is the zimmerman telegraphy?

Answer 1

The Zimmermann Telegram was a secret diplomatic communication sent by German Foreign Minister Arthur Zimmermann to Mexico on January 16, 1917, during World War I. In the telegram, Germany proposed a military alliance with Mexico, promising to support its claims to Texas, New Mexico, and Arizona if the U.S. entered the war against Germany. The British intercepted and decrypted the message, leading to its publication, which stirred public opinion in the United States against Germany and contributed to the U.S. entering the war. The incident highlighted the importance of communication intelligence in wartime.
