Aye boss he is and it might help some to comprehend his irrational and somewhat paranoid ramblings. The geo-political equivalent of the one weird kid in class no one ever liked now might have nuclear weapons and no friends. Its Columbine on a global scale. This is one of the reasons South Korea's government is playing police negotiator trying to "talk him down" rather than just blasting them. This is not to say the ideas of reunification are bogus, every Korean I have met would like to see reunification happen but they said that this "nuclear issue" has given the government a certain impetus to get off their collective arse and do something about it before things go tits up again.
"The purpose of fighting is to win. There is no possible victory in defense. The sword is more important than the shield and skill is more important than either. The final weapon is the brain. All else is supplemental." - John Steinbeck
