I have read several articles dedicated to the collapse of the Soviet Union recently. These articles attributed the breakdown of the Soviet Empire and the fall of the Communist system to a variety of the weirdest agents. There are analysts who are so uninformed as to believe that the Soviet system came to an end as a result of the actions of President Reagan or even the CIA (yes, the same CIA that failed in every single major operation it ever attempted to carry out.)
From somebody who saw the disintegration of the USSR from within the country, this is what happened: Forget Reagan, Bush Sr., the CIA, the FBI, and James Bond. They had nothing to do with the situation in question. There was a certain group of people in power in the Soviet Union. That group of people decided that the economic system of the Soviet Union couldn't be milked for much more profit because it had worn itself out completely. So they introduced a new economic system (which, of course, had to be accompanied by a new political structure and a new ideology) that allowed them to remain in power and exploit that system a lot more profitably.
So, in reality, there was no real collapse, breakdown, or anything of the kind. The same people who were in power before, are still in power now in the countries of the former Soviet Union. It is funny how Americans, who have this weird delusion that they are the root cause of pretty much everything in the universe, keep trying to find reasons for what happened to a huge country on a different continent within the US.
