Quick question: How do you use nuclear technology that is for "peaceful, power purposes only" to defend your country?

It seems Iranian Defense Minister Mostafa Mohammad Najjar had a little Freudian Slip today, oops.

Iran's defense minister on Thursday vowed that his country would "use nuclear defense as a potential" if "threatened by any power."

With a suprised look on his face, Mostafa's eyes dart about the room. "Umm, did I say that outloud"?

Hmm, I wonder what he's talking about? Could it have something to do with all of the nuclear facilities they have hidden underground all over his country?
