Even if NK smuggles a nuke, covered in lead and carbon, onto a covert freighter with a Japanese flag, there's still the matter of spies and ****. I know the Cold War is over, but I think it's safe to assume that the US has a couple of guys in NK keeping tabs on this stuff.

Whatever, Jack Bauer will handle it, assuming he's still alive.
