Why did the Soviet Union disintegrate? Why did the Soviet Communist Party collapse? An important reason was that their ideals and beliefs had been shaken.

Кубло бандитів, кагебістів,
злодіїв та ґвалтівників
у стольному засіли місті
як партія більшовиків.

Few people understand the magnitude of the catastrophe that happened late in the 1980s when the Communist Party had failed to modernize the Soviet Union.

I came out of the Soviet Union no longer a communist, because I believed in personal freedom.

Of course the biggest mafia in Russia has always been the government; in Soviet times, the Communist Party, and now a circle of former KGB and FSB.

If the Soviet Union let another political party come into existence, they would still be a one-party state, because everybody would join the other party.
