British Foreign Affairs Office, London, February, 23rd 1917. In the afternoon, Arthur Balfour, the foreign secretary of the United Kingdom, hands the American Ambassador Walter Page a sheet of paper. It's an intercepted message sent by Germany, encouraging Mexico to enter the Great War against the United States. In short, it's the type of message that can change the course of history! How will this staged and dramatic charade of the Zimmerman Telegram change the course of history?
