Good points. But if we attack we have to destroy the dmz forces to protect the south. If we do it right we obliterate the entire regime and install the south Koreans as rulers nof the north. Here is the distinction in my mind. They have repeatedly threaten our country and yesterday they threatened our forces in Japan. That is where we bomb quickly. And that applies to China but no blustery threats from them yet. Trump is not to be tested with threats to attack us. They fired four ballistic missiles yesterday. They expressly threatened to use them on our Asian forces. It is punch out time. Their collateral damage is their fault because of their big mouth. The doctrine of preemption is only valid if the enemy 1. has capability and 2. makes a direct threat on this country. neither of those elements existed in Iraq but both exist here.
Very good post
