It's European invasion

America is the land of immigrants, including Nazi.
But why don't we return to hi-fi?

Eropean Invasion?? How about Lockheed Martin?

Let's not mince words about von Braun.  He was an officer in the SS and his weapons program used large amounts of slave labor.  He was a Nazi.  The US welcomed him and his team because we did not want the Russians to capture them.  And yes, von Braun, like every other SS officer, definitely did not want to be captured by the Russians.  I wonder why?

Von Braun was the father of the US rocket program, but a far more interesting person is the woman who thwarted his work at Peenemunde.

Many of the highest ranking Nazi brass actually did not fair too well in US (the Allies) hands. We hanged them. But Von Braun was not (rpt not) as guilty as the highest ranking Nazis and obviously could be of use to us.

What happened to great American innovation? Edison. Steve Jobs. Nikolai Tesla. Ford. Bell. Oppenheimer.

typically in fascist regime all investment goes to military and police and there's no room for anything else.
that's my gentle top-down estimate of what's going on.
