Soviet Union will collapse from 1980 till 1985

Andrei Alekseevich Amalrik : writer and dissident
There is another powerful factor which works against the chance of any kind of peaceful reconstruction and which is equally negative for all levels of society: this is the extreme isolation in which the regime has placed both society and itself. This isolation has not only separated the regime from society, and all sectors of society from each other, but also put the country in extreme isolation from the rest of the world. This isolation has created for all—from the bureaucratic elite to the lowest social levels—an almost surrealistic picture of the world and of their place in it. Yet the longer this state of affairs helps to perpetuate the status quo, the more rapid and decisive will be its collapse when confrontation with reality becomes inevitable.
