Other dictatorships like the Spanish and Chilean have declined but not in such a dramatic way. Reality hit him like icy water and his moves, supported enthusiastically. Sleepless nights may haunt Gorbachev for the rest of his life. Nobody could have predicted what happened. The concept of NWO carries its own internal poison.
Total power is a blind machine, no place for idealism in it.
It's a drug blocking the brain from everything but self-adoration. Such a demented conclusion was not predictable. Gorbachev's cruel mistake was that, blatant pacifist that he was, he forgot that we live in a Darwinian universe.
