I don't believe you believe a word of what you just said. And, if you do, more's the pity!
Last I checked, using such incendiary language on Twitter and in impromptu remarks to journo questions while you're at your own golf club is not the manner in which the last 5 or 6 Presidents have communicated their feelings about global thermonuclear war. Maybe someone needs to sithim down in front of his phalanx of TVs and put War Games on for him! Question is, will he understand the game of Noughts and Crosses (Tic-Tac-Toe)?!
Just saw a collection of video clips where Trump said one thing off the cuff, then one of his Cabinet Members said theopposite in a press briefing within a few hours of his comments. It is like following a puppy around with a roll of paper towels and Lysol!!
While US Presidential policy will always be, as defined in his Presidential Oath of Office, to defend the United States, the manner, tone and language of the communication of that ideal has been, in the politest terms I can muster, "unique."
