I don't know what Hexbear's general opinion of Furr is, but I'm currently reading through his book "Krushchev Lied" and it's an interesting picture. I don't think you're wrong, the USSR was absolutely at a tricky point and needed to adapt to stay competitive, but (assuming Furr is even sort of correct, I need to read other historians (and probably learn some Russian as well)) he was pretty damn shady in undermining Stalin's image.
And for the record, I do think he handled the Missile Crisis pretty well, all things considered.
