The whole thing about technology and history and German superiority is that it didn't really matter that they excelled in one area (Rockets) because we whooped them on all the other fronts. They shot themselves in the foot by the whole oppressive regime thing since most people with a brain and means (including scientists) fled the coutnry.
Germany never effectively used its V-2 Rockets. More people were killed assembling them than were killed by them landing. Their best scientists fled to the good ole US of A. Verner Von Braun became a Naturalized US citizen. He was arrested briefly by the Nazi's too. He's American now. Einstien revoked his German citizenship by request and became a US citizen. They are just the most famous of thousands.
In the 15th Century China had the best Navy in the world. They could have "discovered" America before Columbus, but they refused to put it to good use.

Considering that my uncle Nicklaus Gabriel worked on Rockets and in NASA as an aeronautical engineer through every phase of development from 1946 until the mid 70s, he would very surprised to be considered eurpoean.
Just because they were working well in that direction does not mean that the technology needed to get to the moon was european, especially when you consider the 30+ years of intensive R&D, all right here in America.
While we used the German research to bump up our own programs, we would have still achieved the same results.
