I've been reading through the last few pages with interest and thought I might just add my own input here. South Korea probably wouldn't be able to defend its self from any attack from NK, due to a variety of reasons. As Danq said, it would be selfish and immoral for America, a country with massive amounts of military power, to stand by and watch one democratic country filled with people with their own opinions (I say this because NK citizens are essentially brainwashed) be overtaken by communism. After all, isn't one of the things that America holds dear the concept of democracy? I would have thought that the American government and American people would like to stem the spread of communism wherever posswible. Any opposition that invading North Koreans encounter will just be disposed of (whether that be physical or political opposition). How can one possibly see this as a good thing, and how can one not agree with defending an ally from this attack which will end up with millions of people being denied their freedom of speech and expression? I would say that Ring_World's argument about China is pretty much invalid now. Granted they used to be a lot more on NKs side, but that has changed quite a bit now. Like TTanT, I don't really have enough knowledge about this to really get into a massive debate, just thought I would share my thoughts.
