🤔If I told you that in 1944, Adolf Hitler ran the most sophisticated and successful space rocket program on earth, would that change your opinion of him? Should it?
Would that make you think Adolf was a rocket scientist? Or do you know that Wernher von Braun was the rocket scientist?

We see from this real example, that post world War II, after the Nazis were defeated, that Wernher von Braun kept making rockets, at the same pace.
It appears that the magic sauce, was "the world's best rocket scientists, with sufficient resources," not "fascist philosophy."

(Werner von Braun was a nazi. A rocket nazi is still a nazi. A nazi living in the country that helped defeat the nazis, is still a nazi. A nazi with a US government job, is still a nazi.)
When Hitler was being defeated, some people said, "Good! Hitler is bad for the world!"
Other people said, "Noooo! Now we won't walk on the moon! I have long dreamed of being interplanetary! Let Hitler keep building rockets!"
If you lived in 1944, which camp would you be in?
3/N
Seems like a tough call to me. Yes, von Braun was a Nazi, in a situation in which NOT being one might have been detrimental to his plan of getting into space (at minimum).
The Soviets were totally gunning to vacuum up that talent, so I think Operation Paperclip (the recruitment effort) was oriented toward preventing that outcome.
There were indeed crafty American (and British) engineers who could have filled in, so I wouldn't see difficulty in reaching the moon, EVENTUALLY.
(I just know I'm going to get myself in trouble here, aren't I?)
The more interesting question to me (so far) is the guy who was responsible for PRODUCTION as opposed to research. I can imagine the German government coming to him and saying "here's a bunch of Jewish slaves. Use them to build your rockets. You don't have a problem with that, do you?"
(That guy did eventually get deported.)
