On the face of it, one would think there really aren't a lot of conventional options for 37,000 against a million man corps of fanatics primed to go, even when you add in what the ROK forces can do. I'd certainly welcome critiques from anybody with better and more up-to-date information. The Korean terrain favors defense and maybe things aren't on such a hair-trigger. This shield pounding by the North Koreans is probably mostly noise, but it can't be entirely ignored.
