I highly doubt we'd engage NK since it would be fairly simple to play defense along the DMZ and just blockade the entire country from trade. They'd hurt very badly without Chinese support and I doubt China would be willing to fight us just to trade with NK. Just like Kosovo, denying them the basics like food, water, electricity would likely be highly effective.
Thoughts? I think the chances of NK acting militarily is slim at best, but just for giggles what do you guys think?
