He was the equivalent of a U.S. major, you say he was rank and file???
He was a very intelligent person and didn't think much of Hitler. I think it is safe to say you are just restated my opinion that science and government will get in bed together even though they are operating on the same goal with different motive. I personally have no problem with the guy, he wa a nazi, then he wasn't, now he's dead, and we have been to the moon. Its all good.
in 2002 a former SS officer at Peenemünde told the BBC that von Braun had regularly worn the SS uniform to official meetings. He began as an Untersturmführer (Second lieutenant) and was promoted three times by Himmler, the last time in June 1943 to SS-Sturmbannführer (major).
