President Trump is not 'baiting' Un, rather, as I said, he is speaking in terms that Un and his generals can understand.

I am dismayed that you interpreted what I said about the safety of nuclear weapons is me thinking of myself as and authority. I am not. I am however, a degreed, experienced engineer with some knowledge of how nuclear weapons are constructed. The incidents I refer to demonstrate incidents where the device did not detonate after exposure to extreme forces. In 1980, in Arkansas, a Titan missile in a silo exploded as a result of a liquid fuel leak, which blew the 740 ton silo lid off and catapulted the 2nd stage and warhead into the air. The second stage then blew up and the 9 Megaton warhead was thrown 100 feet away from the entrance to the facility. The designed in safety systems worked and the warhead did not detonate and no radioactive material was released. The forces on the warhead were immense. Sounds pretty safe to me. Titan missiles are no longer active.
