Zimmermann Telegram: Tough-o-Meter
Zimmermann Telegram: Tough-o-Meter
(1) Sea Level
The Zimmermann Telegram is only seven sentences long—and that includes the signature. Sure, it's longer than a Tweet, but it's not much worse than an annoyingly long text message.
The grammar and wording is a little wobbly and awkward in a few places because it was a telegram sent in code, but as far as consequential historical documents go, this one's as easy as they come.
