George H. Wittman's web article today, on the threat posed by a dangerously unstable North Korea (Road Back to Pork Chop Hill), prompted an interesting and informative criticism from military expert Stuart Koehl. Koehl has a much less dire assessment of the threat posed by the Kim Jong-Il regime, counter to Wittman's warning that combined South Korean and American forces would be hard pressed to maintain a strong position on the peninsula, as they did in 1950, in the event of an all-out North Korean assault.
I've hoisted Koehl's argument from the comments on that article. It's too long to post to the blog, so I've placed it here.
