This has been common knowledge for three years now. It would appear that either the news media are wilfully supressing this information, or simply that the Yanks don't care.
I suspect it's six of one, half a dozen of the other. Remember that it was the US who made off with most of the Nazi scientists and their findings (including those of Mengele's disgusting human experiments) after the war. There would have been no moon landing had they not captured Wernher Von Braun, the Nazi scientist who designed the V2.
