And that's of course the US version of the story. Very cute, but I can tell you from lots of anecdotal evidence that all that ISS work was a drop in the ocean as far as Soviet space program was concerned.
Rocket scientists didn't go to work for rogue nations. You have to understand that Soviet space industry was (and still is) veiled in secrecy. Think of it as SkunkWorks but on a massive scale and with 100x of security officers. You couldn't just hand in your resignation and go work for Iran. It just didn't work this way (it still doesn't by the way). For example, people with a security clearance were required to keep their travel passports with HR and they were not generally allowed to leave the country unsupervised. That's if they could get passports issued to begin with. Perestroika or not, all this security scaffolding was still in place and you bet it was functioning. The state was still guarding its secrets and know-hows. Granted, it neglected people behind them, but it wasn't going to let others access its technology.
In my personal opinion, manned space flight (launchers, spacecraft, in space operations) has little technical overlap with solid fueled ballistic missiles.
