Explanation:

The Zimmermann Telegram was a confidential diplomatic note declared from the German Foreign Office in January 1917 that offered a military agreement among Germany and Mexico in the event that the United States started World War I against Germany. The telegram was intercepted and decoded by British intelligence.
