Iran's posturing (engage caricature mode) is like a madman wearing a t-shirt emblazoned with a mushroom cloud and the words "We will vaporize you, you filthy infidel nation!", with a big lump in its trousers -- who, when asked, "Is that a nuke in your pocket, or are you happy to see us?", replies, "We have stated that we are not interested in nuclear weapons -- and we are not happy to see you."
Ambiguous, open-ended, and Clintonian-parse-speak to the nth degree.
It's a clumsy attempt at "plausible deniability", i.e., "We didn't say that we didn't have nukes, and we didn't say that we wouldn't nuke you!"
And our response is to pretend that we do not see the obvious.
That may be what they call it. We should call it "glass parking lot day" (for those un-informed, a glass parking lot is what remains after a nuke blast on the desert countries)
