We will not go nuclear first. We will not go nuclear unless Kim is able to detonate on our soil, even if he tries to do so. We will detonate only if we are hit with WMD.
Let us assume the NKs attack across the DMZ. US would immediately send more forces into SK. Where would another 50,000 troops come from? How many of our Naval forces are within useful distance for attacks on NK?
Like with did with Iraq, right?
Doesn't wash, does it?
