This piece of text probably is somewhat right, read it with caution though.
I'm under the impression that "Um" will be more lenient than his predecessor is. He has had loads of connections with the chinese, who most likely have told him what to do and how to behave. After all, it's not exactly a good thing for them to have such an aggressive bunch of irrational militarypsychos, acting like they own the world, at your backyard. What comes to the man himself, he's an educated man and he'll most likely concentrate on his own country, which is overruled by famine and is technologically decades behind it's neighbouring countries. The people is devastated, but because the country is ruled with fear and dreadful actions, they can't do anything about it. I have a strong feeling that Um will atleast try to make them feel better, before he starts to bark as his predecessors have, only, done.
The real question mark, however, lies in the fact that the real ruler of the country might have been the leaders of the military force for several years now, actually ever since Kim-Jong-Il got old and had that cancer a few years ago. There is a possibility that even after Kim-Jon-Il's death, they won't give up their power and let Um rule the country the way he wants to. In that case North Korea will continue their current activities like nothing had changed at all. Um might become a puppet, who only represents the power, but can't say anything on what the military has decided to do. With that, nothing would change and we'd still have the same ole North Korea discussion going on until something major occurred, because if the situation doesn't develop from what it is now, something big will happen eventually. And that might not be a good thing for any of us.
@Thousand:
Doesn't really apply to South Korea then does it seeing as they're freaking neighbors? O_O
No, it pretty much doesn't. That's why SK is trying to balance between angering their neighbors and being good to them. They don't want to get blown up.
Of course, we have to remember that the Koreans are actually one people divided into two nations and their (the SK'ans) good deeds can be explained as they feel a bit of pity towards their northern "brothers" and try to help the people, whenever the nutcase rulers let them do so.
