Well do you have any evidence that he ever apologized? Just because he wanted to surrender to capitalists instead of communists doesn’t mean he renounced anything.
Second, I have not seen any quotes from him that showed a deep sympathy towards the Nazi movement, only to the cause of space travel.
Third, Freeman Dyson had this to say regarding von Braun:
... Whatever von Braun knew about the terrible treatment of the prisoners at the Mittelwerk factory, he did not himself, so far as I know, administer or order that treatment. In my view, von Braun was morally no better and no worse than other patriotic soldiers who take part in the atrocious killings that are inherent in modern war. The only qualities of von Braun that were exceptional were his talent and his dedication to the exploration of space.
“Well do you have any evidence that he ever apologized? Just because he wanted to surrender to capitalists instead of communists doesn’t mean he renounced anything.”
What do you think von Braun owed an apology for?
