In Cuba black people were discriminate by society. In the first three decades people who have pointed on this problem or exercised any other critic could expect tracking. Che Guevara once said, that “The negro, is indolent and lazy, and spends his money on frivolities, whereas the European is forward-looking, organized and intelligent.” Only 9% of the members of the Communist Party of Cuba are black.
In many countries of the Warsaw Pact Jews were called "counter-revolutionaires" or "Zionist agents". Also Joseph Stalin stated that "Every Jewish nationalist is the agent of the American intelligence service. Jewish nationalists think that their nation was saved by the USA. . . They think they are indebted to the Americans. Among doctors, there are many Jewish nationalists." Already Karl Marx declared that "Money is the jealous god of Israel, in face of which no other god may exist".
