Comment on Trump's knowledge of United States and Russian/USSR history and express your concerns about the situation.
Obviously, trump knows zip about US-Russian/USSR history. Two much more serious situations come to mind immediately, first Soviet Premier pounding one of his shoes on the podium at the UN, shouting, "We will bury you," and second, the Cuban missile crisis of 1962.  The man is an ignorant dunce--and a lying hypocrite--surrounded by equally ignorant amateurs.  We are in grave danger.
