Relative to nukes, NK’s ability to one, miniaturize, two, launch, three, make it through our strategic defenses, are very low. And if one did, the damage, again relative to nukes, would be minimal. And in a matter of hours his country would be wiped off of the face of the earth. But to allow him to develop, and build an arsenal is reckless. We will have to deal with him and the longer we wait, the more damage he can do.
