One of the world's mad dogs

North Korean leadership have repeatedly demonstrated a propensity for provocative language towards a nation capable of turning their country into a smoking parking lot - without resorting to any sort of WMDs. They have continued to ramp up the rhetoric, even occasionally shooting live weapons into South Korean territory. They've managed to piss off their sole powerful and reliable ally, and have continued to act in a manner that, in any other time or place would result in a war of serious proportions. One day the leaders of North Korea will be put down, like the mad dogs they are.
