The news has spread around the whole world already. Kim Jong-il is dead. The reactions were swift. The most concerned ones are of course neighbours South Korea and Japan, although there's a certain sense of cautious optimism
sneaking in. The Japanese PM Noda summoned a special meeting of the security council of his country, and warned his ministers that Japan should prepare for unpredictable consequences, including financial ones, and some tension along the borders. The general secretary of his cabinet Fujimura announced that Japan is working in close collaboration
with the US, South Korea and China in searching for more information and coming up with a common approach to the situation, and that's not easy as you can imagine, because NK is a very secretive regime and doesn't share a lot of intel even with its ally China.
So the moods are pretty strained, and Japan and SK are preparing for some nasty actions from NK, at least until (and shortly after) its new leader makes the full transfer of power and asserts his position.( Problem is, that may take a while. )
Side question. Hypothetically, if NK decided tomorrow to re-unite with SK, what do you think SK's reaction would be? Similar to the German re-unification? Or hostile? A mere "Meh"? Or maybe "LOL, no way Kim"? Suggestions?
