The end of WW2 saw the Americans and Soviets rushing to take over Germany so we could acquire as much Nazi tech and scientists as possible. Our ICBMs technology was based upon this Nazi technology, and now SpaceX and NASA tech is based upon that as well. While the origins of it are based upon a destructive goal, they have enabled the Mars rovers, Moon landing, Hubble telescope, etc. Technology should be evaluated on its own merits and not its origins.
