Trump casually talked about using nukes saying "Why do we have them, if we are not going to use them." Trump is a blustering big mouthed bully. Those are not the characteristics of a diplomatic person. Trump is an embarrassment when he meets foreign dignitaries. He leers at the women and insults the leaders. He pays no attention to protocols. I am sure we have people telling him what is acceptable, but he does not listen. He pushes leaders out of his way and walks in front of royalty.
