It is a well known fact that the U.S. government welcomed a great number of Nazi scientists to the US where they could continue their scientific research and experiments.
One of the greatest benefactors was NASA, without the knowledge of the Nazi scientists who worked on the V1 and V2 programs the NASA space program would never have been possible.
In fact the idea of the International Space Station was based on the Nazi plans for a ‘death ray’. The Nazis had secretly been working on an orbital space station based on the ideas of Herman Oberth. Their plan was to install some sort of reflective shield to harvest the sun rays and convert them in a ‘death ray’ or ‘Sun Gun’. The death ray was never developed of course, but part of the plans for the orbital space station were used.
