Bottom line, when it comes down to it, the US would knock NK's dick in the dirt. You know it. I know it. The rest of the world knows it. NK sure as fuck knows it. Thats why I highly doubt you actually see them make a move. They know if they attacked South Korea or any of our allies, we would bury them. There is alot of common logic in the situation that everybody knows. The big wildcard here is Kim Jong is crazy as a shithouse rat. Even though logic tells him they will be crushed, he doesn't care. He obviously doesn't care about the people of his country, and I don't think he has long to live in this world naturally anyway. So, what does he have to lose?
