The North Korean nut and the White House nut
Unbalanced North Korean dictator, Kim Jong-un, has the mentality of a five year old. There is little doubt that he would launch his nukes if he feels we are about to attack him. His targets would probably be South Korea and Japan.
Unbalanced American dictator-wannabe, Trump, is an arrogant buffoon with the attention span of a five year old. There is little doubt that his ignorance of just about everything could let him stumble into a nuclear exchange.
IMO, both of them are clueless about the consequences of using nuclear weapons in today's world. Once one is unleashed, no one knows how far the insanity would go.
Hopefully, the generals under both of these head cases would somehow see to it that it didn't happen.But what if they can't or don't?
I believe that we are closer to the use of nuclear weapons than at any time since the Cuban Missile Crisis. That event had sane men on both sides (JFK and Nikita Krushchev). This time around, the mental stability of both leaders is in question.
