I think the scenario is very real. Consider the two Koreans constantly provoke each other. Just a few days ago, two Korean warships fired a few shells at each other (although none was hit). http://news.yahoo.com/koreas-exchange-fire-near-disputed-sea-boundary-120749771.html So what if another Korean War broke out? What will happen? Lets say 1. What if nobody interferes? I believe South Korea will prevail due to much better equipments and training as well as an ecnomoy 10x the size of the North's. But not before North Korean's artillery make a ruin of Seoul and other cities near the 38th parallel. 2. What if there is outside intervene? Lets say what if the US helps South. Will China sit by and watch or will they aid NK like they did in the first Korean War? Back in the 1950, China did what they had to do because the US aided Chinese nationalists in the Chinese civil war which just ended in 1949. They saw the US as hostile to them, and they believe the U.S. would continue to push cross the border once NK was finished. So if the US and China both intervene again, what will the outcome be? Another localized war kept under control, or will it turn into a WWIII?
