What you just wrote is why I think the Soviet Union would have collapsed anyway. Too many countries and Republics were not happy being a part of it. Also, too many Russians were tired of it too.
They would not have collapsed anyway, that is why it is so hard to find those predictions before the media created them, and many of us thought in the late 70s that they would make their big move in the mid 1980s.
Some of us were very thankful for Reagan fighting them in Afghanistan, it really messed with them.
