One of the marks of dangerous dictators - not an infallible marker, but pretty frequent - is the suborning of the military so that the officers and soldiers believe that their loyalty is to the ruler, not the country. Hitler, Stalin, Mao, Mussolini, sure - but also Julius Caesar, Emperor Hirohito, Pol Pot, the Kims, Franco, Ceausescu, Genghis Khan. Exceptions might be Ferdinand Marcos, Chiang Kai-Shek. Sorta.
So you tell me. Do you think you could find a single person in the US military who believes his or her loyalty is to Donald Trump rather than the USA?
