That does not match my understanding of the history. A) Didn't the US prevent technology transfer to the USSR as much or more so? B) The analyses I have seen have said that the reason the USSR fell is because it could not match the USA industrial/technology base, and specifically that in trying to keep up with US defense spending, they ended up spending 12-15% of GDP on defense (compared ~5-6% in US at the time), and that this was a big problem for them, that they were spending more than they could afford on defense. C) At the time the USSR fell, which the US considered positive and a victory... it still didn't have a "modern industrial/technology base", did it? At that point, we started helping Russia (not the USSR) develop that, and encouraged privatization of the economy... that was done in a way to create an oligarchy... that led Russia to where it is. i don't understand what you're talking about, a history where the US "made the mistake of allowing the USSR to buy its way to a modern industrial/technology base". By doing... what? That resulted in... what? What actions or inactions of the US or USSR are you talking about?
