Thats an interesting take, loosing the ROK as an ally if the US goes to war with the DPRK. Although I personally don't agree, just based on the amount of influence the US has there. That would be a curious turn of events. I would also keep China, as the wild card, in mind. Also, just considering the behavior of the people in DPRK, there would appear to be a big divide between the Kim regime and the supportive class versus the outlying people of the country. The hockey team is good for the unification, in terms of the social effort, but from a political or military perspective I cant be certain that it really has an impact. I think its business as usual over there.
