We won a nuclear war... WWII. We won because no one else had them at the time. Now we're fighting to make sure that no one else ever has them again. Except us. So we always win.

We gave up on NK because we've already lost one war over there and we know we'd lose another one. China would enter of the behalf of NK and kick our asses double-time.

NK and Iran with a surprise Saudia Arabia entering in to whoop on us, who will have scared away anyone who might support us. We're fucked no matter what.
