From what I've heard, N. Korea has mucho artillary, most of it in caves that open to the North face, so that the piece's can be moved out to fire, then retracted to protect from counter-fire. Seoul (SP??) the Capital, would be flatenned in no time, with not only a huge loss off life, but also total disruption of the entire South. As I recall, a few years ago there was talk of moving the Capitol a considerable distance to the south, out of Arty range.
In any event, that little pot-bellied dictator really needs to be eliminated, along with his equally diabolical Sons, various ministers, czars, etc.
and let the North be like the South, free and prosperous.
