Former Secretary of Defense Donald Rumsfeld has done an admirable job building out a digital document archive from his time in the government on his website, While I was watching the events in Libya unfold, I decided to search his papers to see what he'd written on the country. In so doing, I ran across a document that left me flabbergasted. It's a message (probably an email) that Rumsfeld sent to then Under Secretary of Defense for Policy Douglas Feith on April 7, 2003. ...

The memo's tone is so casual about such complex and important topics that it prompted Technology Review editor Jason Pontin to ask me on Twitter, "Is this a parody?"

But no, the memo is real.
