I think you mean the Americans sold all those bits to the Russians.
You also sold things to us, and lent us money, which wasn't fully repaid until nearly 50 years later.
The problem with this is that the Germans were also given all sorts of, well sold, things from American corporations, tanks and planes in particular I believe.
GE had quite a few links with Nazi Germany, I am sure there are more, but it is early, I love history but it's not my forte, so I would have to look for this info.
