Hitler came about at the right time, and with the right rhetoric, to make great evil.

"Great" can simply mean "very large." I meant that his evil was very large.

Because the media and government whipped up nationalistic sentiment and painted every other country as a boogieman. Sound familiar?

A lot of that was down to Goebbels' coaching that included written prompts regarding posture, speech speed and emphasis, although Hitler's image and general 'on the mic' persona were a carefully crafted fabrication.

Presidents Reagan and Obama would know all about the above. Kinesics (body language) accounts for something like 40% of what's being said while actual actions can show domination in a particular situation...

Hitler would often jostle with people while shaking hands in order to show he had the "upper hand" and when it seemed he hadn't, he'd place his other hand on top, its a well noted tell(or subliminal sign)of insincerity.
