The cold shower didn't help so here is my 2 cents..
The only reason nKorea is huffing and puffing is b/c they are scared and are worried that after GW finishes with Iraq they will be next. If it wasn't for the fact China has a long history with Korea we would be slapping them around right now. nKorea is a joke and they know it. We don't need to negotiate just let them continue to self destruct !!!!
As far as them having a missile to hit the US, big deal and so what. When GW made his point that if anyone uses WMDs we would respond heavily that pretty much sealed the deal. Kim is a fanatic but he loves himself too much to commit sucide and to risk losing the worship of all his people.
