Aree you counting on the Chinese to go along with this?
Looking at the plus/minus for China, with respect to dispensing with Li'l Kim's antics, I'd say there's no question that the "plus" side wins hands-down. Not just militarily, but also commercially.
If you think it's cheap for US companies to outsource to China, it's even cheaper for Chinese companies to outsource to NK.
I think, reluctantly, the Chinese will be an ally in this. They don't want to see another Communist nation fall, but I think they also realize that Kim Jong-Il is a nutcase and if he gets a bit roney one day he just might turn the missle launcher around towards them. I don't think they're comfortable with a nuclear NK.
