Why Doesn't Kim Jong-il Make Any Sense?

According to BBC News, Kim Jong-il, North Korea's leader, wants a "nuclear-free" peninsula (BBC News). Doesn't this seem slightly ambiguous, considering that he just supported the testing of a nuclear warhead in his own country exactly one month ago? Now Mr Kim is beginning to have disarmament talks. He even "expressed his intention to honour a 1992 declaration to preserve a nuclear-free Korean peninsula in accordance with the wishes of his father, the late leader Kim Il-sung. "

Personally, I don't think that Kim Jong-il really gives a hoot if the peninsula is nuclear-free. I don't think he gives a hoot about his dead father. If he really had did, then he wouldn't have supported the testing of the country's first-ever nuclear bomb. Perhaps, he was just curious if his scientists could really come up with the technology. Or, maybe he wanted to see how big of a boom it could really make...All I know, is that he should've thought twice before making the statement about preserving a nuclear-free Korean peninsula in accordance with the wishes of his father. If he really wanted to do this in honor of his father's wishes, then you'd think that the leader would have done everything in his power to stop the project before it even got close to the point of testing. Right now, he just seems like a man in power trying to gather some support from the world. He didn't expect this type of reaction from the world, so he is going through the motions of undoing it.

Someone try to explain this to me!
