This must be the "red line".  Trump must declare to Kimmee that the minute this happens, all our air power and naval power will annihilate North Korea. No more idle threats or rhetoric.  Games are over.  I imagine folks at Anderson AFB, Guam are  already working overtime loading up their bombers with nuclear bombs and all ships and subs around N.Korea are ready with their missiles.  That'll teach him to call Trump a dotart.
