This will not be a guerilla war if it happens. It will be conventional and the South Korean state will absorb the North as the North army collapses under the massive firepower that will be brought to bear. The people of the North are aware of the world through border leaks and new technology, they will not resist the take over if the North regime is stupid enough to start this one.
If it is mountain top to mountain top take them 1 at a time. It will be very costly to do. Nothing there cost wise to waste a nuke on.
So one way or the other we would loose. Never get in a fight with some one who has nothing to loose and will fight to the end to kill you. There is the problem why would any one want N.
Korea if they gave it to you? To go to war over it? Not Smart.
To punish it how? They have nothing there.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
