They're only very dangerous if you consider them as children instead of the soldiers/thugs they really are. Thankfully they only tote AKs around, not a 105mm cannon.
they can lob shells at that rate for 4 minutes. i guess NK must be the most sattelite monitored country in the world for the last 60 years. and it's not vast. we must have counted everyone of them by now. Mass attack from them will end in their mass slaughter on a scale that will outdo Verdun, the Somme and Passchendaele. from what it looks like, they all have to move over only a couple of mountain roads so moving will be slow and in the open with nowhere to hide. over a frontline that is merely 200 miles wide and must be the most heavily defended stretch of land around i wouldn't want to be one of the 1.1 million when they start cleaning out their clusterbomb stocks in the name of self defence. Everybody knows this. and it doesn't take much blast to criple their derilict buildings and infrastructure Kim knows this to. if he moves, it's over for NK
