Modern Dictatorships are different than 20th century totalitarian dictatorships

A corrupt dictatorship by Trump won't look like a Hitler or Stalin's dictatorship. Here is What Frum says in his famous article at Atlantic:

Whatever else happens, Americans are not going to assemble in parade-ground formations, any more than they will crank a gramophone or dance the turkey trot. In a society where few people walk to work, why mobilize young men in matching shirts to command the streets? If you’re seeking to domineer and bully, you want your storm troopers to go online, where the more important traffic is. Demagogues need no longer stand erect for hours orating into a radio microphone. Tweet lies from a smartphone instead.
