And an addendum: one of the interesting questions is, how much influence does China have over North Korea? Some Chinese told that North Koreans tend to act by themselves, but I can't be sure about that. My understanding is that China does not want to change what is happening inside other countries. On the other hand, I guess they don't like North Korea doing stupid things like the torpedo incident as they pretty well know that there will be international repercussions.
Now that North Korea has got nukes despite the international community saying don't do that, how does Kim Yong-il think he can prove he has disarmed, if the proposed bargain idea is correct? Especially when it is not allowed to have international inspectors in the country. I was rather perplexed when they announced that something big had blown up in North Korea that US or NATO didn't respond by then.
