yeah the best part of it is the North is hostile towards the south. They already sank one of their ships and get into little border skirmishes. I don't see the North partaking in even a short term war for very long. The people are starving and I'm sure the defectors would come pouring in.
I think you missed the followup news on that ship sinking in which S. Korea and U.S. officials said the evidence turned out to indicate is wasn't a N. Korea torpedo at all.
