The north might do some damage early on but the south will stomp them into the modern world in short order.
My fear is that the little fat man will order a strike just to be contrary. They might make some gains for a time—make take South Korea’s capital then hit a snag as bombers wreck North Korea. What will China Do? Who knows? What will Obama do—I predict zip! He will go to the UN as our troops are slaughtered. Maybe this will put an end to the farce that is North Korea. South Korea will be devastated —China may like this as it will knock out a rival for far east trade. I see a three to six week war—The Obama can earn his second Peace Prize.
