I was surprised not to see David E. Hoffman's 1984 book _The Billion Dollar Spy_ in your sources list. If you've not read it, it's well worthwhile. It's a long, detailed account of Tolkachev's spy career from the point of view of the CIA and the embassy in Moscow and gives an excellent sense of just how difficult it was to spy, or even just meet spies, in the Soviet Union at that time.
I sometimes wonder if the Chinese could spy on Mil/Space tech while being in the US on CCP's payroll, what stopped us from doing the same? I'm certain that India could have afforded letting a few do it, yet it didn't, thanks to lack of political vision and strategic far-sight.
(Also, I'd have tweeted this but I dread a certain VPN hack on my account. :P)
