Beware of Pretend WMD's
From Meet the Press last Sunday:

RUSSERT: Not having found weapons of mass destruction, why do you think Saddam engaged in this cat-and-mouse game and didn’t come clean?

BLIX: That’s a good question, and one possibility is that he was like someone hanging a sign on the door, “Beware of the dog,” without having a dog--when he wanted to tell Iran, and he wanted to tell others that “I’m still dangerous.”
