I'm interested to see the outcome of this, North Korea can't win a war if it arises but the rest of the world doesn't want to poke North Korea.
Edit: The nuke threat isn't nearly as bad as it was decades ago, their are various countermeasures for a nuclear attack. North Korea is a lone entity that doesn't posses many or even very good nuclear weapons in comparison. We (world outside of the Koreas) have nothing to worry about.
