I'm just repeating what wikipedia says was in the OPLAN, which would reflect what the pentagon thinks. I think it did plan to respond to movement south with a first strike, as you say. But NK know that too, presuming they read wikipedia. I think in practice fighting a war is different from how we might think. Some people say that the problem the NK army would have would be keeping its troops supplied, given the lack of petrol, trucks, and food in NK, and presumably destruction of the roads there. Along with the end of incoming food aid, leading to widespread starvation there. I agree with you that the US would win eventually. To me, it looks like the cost would be an aweful lot of dead Koreans on both sides though.
