Defeat the Space Huns!
While the Nazis had rockets, which for them served as long-range artillery, they didn’t have a space program.
Still, just as the German rocket-community was interested in the works of Bob Goddard, Nazi rocketry likely provided a significant nudge towards space if nothing else:
"I think the space age would not have arrived till many years later," [Wernher von Braun biographer Bob] Ward says, "War, sad to say, spurs technical advancements, whether it’s in aviation or virtually anything else. Space flight was inevitable, but it would have taken a longer time to get under way."
So if Ward is right, space was inevitable even as the Nazis continue to serve as an eternal fount of ideas for the entertainment-industrial complex.
