I keep thinking if I was a South Korean, I would be quite nervous about the North Korean arms build-up. Here you have an already powerful country next door about to go nuclear, and a country that likely considers itself the rightful ruler over you. And if they do take you over, the likelihood is that your life will collapse, considering the vast difference in living conditions between the two Koreas. Essentially, you have one country with vast military power and terrible economics and no political freedom, and the other country exactly the reverse.
What is puzzling to me is that the sentiment in South Korea seems to be that the US is the bad guys, and the North Koreans can be negotiated with, despite what seems to me to be overwhelming evidence to the contrary. (See here for but one example). So my question is what the SK strategy and mindset are. Are they completely deluded? Could they be right? What do they want the US to do? Pull out completely? I haven’t seen any in-depth analysis of this aspect, but the bits and pieces that I read don’t seem to add up.
