Secret WWI telegram holds lessons for today, historians say
NEWPORT, R.I. — In a secret telegram a century ago, Germany tried to get Mexico to join its side during World War I by offering it territory in the United States. Britain intercepted, deciphered and shared the “Zimmermann Telegram.”
Historians, seeing parallels to today, say there’s a lot to be learned.
They gathered at the U.S. Naval War College in Newport, Rhode Island, last week and discussed how a foreign government hacked a secret communication and used the information to sway American public opinion and policy. When it was released, there was a heated debate over whether it was real or what we now call “fake news.”
The message’s publication — and Germany’s resumption of unrestricted submarine warfare — was the culmination of a series of events that drew the United States into the war.
