It’s just a tiny piece of the puzzle — but I think part of the problem is that after WWII we convinced ourselves that “Hitler was a monster”. And it’s true: he was a monster ... but people are monsters. Human nature is very flawed. It’s not a “Hitler” problem, it’s a “people” problem.
The solution is to NOT give a lot of political power to anyone and to NOT let the public be lied to.
The US has certainly failed in a big way. Our government is far too big, too rich, and too powerful, and it controls the media and lies to people all day long. It’s monstrous and millions will die. Again.
Very well said and I fully agree. I see it too. We fail to accept that history always repeats it’s self. We just never learn.
