In 1989-90, Mikhail Gorbachev got too friendly with the capitalists of Reagan and Clinton, who are always the sworn enemies and haters of socialism/communism.
The USSR and the Socialist block collapsed shortly after that.
The same has happened in Vietnam and the People's Republic of China.
Both countries have betrayed the ideas of Karl Marx for a bowl of pottage and a few dollars from the capitalists.
Is Raul Castro in Cuba about to repeat the big mistakes of history?
Jesus was sold out to the pharisee Jews for 30 gold coins.
Nothing surprises me anymore.
