Fidel Castro on the revolutionary importance of the USSR 1970
Today there are, as we know, theoretical super-revolutionaries, super-Leftists, veritable "supermen" if you will, who can destroy imperialism in a jiffy with their tongues. There are many super-revolutionaries lacking all notions of reality about the problems and difficulties of a revolution. They are prompted by sentiments carefully fostered by imperialism and are full of fierce hatred. It is as if they refused to forgive the Soviet Union its existence, and this from "Left"-wing positions. They would like a Soviet Union shaped according to their strange model, according to their ridiculous ideals. Yet a country is primarily a reality, one made up of numerous other realities.
The exponents of these trends' forget the incredible initial difficulties of the revolutionary process in the Soviet Union, the incredible problems arising from the blockade, isolation and fascist aggression. They pretend not to know anything about all this and regard the existence of the Soviet Union as almost a crime, and this from "Left"-wing positions, which is an act of absolute dishonesty.
They forget the problems of Cuba, of Vietnam, of the Arab world. They forget that wherever imperialism is striking its blows it comes up against a country which sends the people the arms they need to defend themselves.
We recall Playa Giron these days. We well remember the anti-aircraft artillery, the tanks and guns and mortars and other weapons that enabled us to smash the mercenaries.
This means that the existence of the Soviet state is objectively one of the most extraordinary privileges of the revolutionary movement. -- Fidel Castro, Granma, May 3, 1970
