The two positions in this thread aren’t as opposed as they appear. Nazis did think of themselves as special boys. That’s why they thought invading Russia was a good idea.
There are sometimes counterfactual arguments where people say “what if the Nazis did X instead, would that have saved them?”. And where a lot of these end up is the realization that for them to have even tried it, they would have had to be something other than Nazis. If it hadn’t been invading Russia, it would have been something else.
Fascism is more fragile than it appears on the surface.
I’m a former Jehovah’s Witness, so I’m well aware of the other groups targeted by the Nazis.
As for technology, they just put on a display of how well they use it. Signal can’t fix dumb. This will always happen, and it will always be an opportunity to exploit.
