Fidel Castro: Yon Sosa led the movement of a group of armed officers in the crushing of whom the mercenaries who later invaded Playa Girón participated. Through a businessman who took charge of the movement's political aspects, the Fourth International fixed it up so that that leader, who was ignorant of the profound problems of politics and of the history of revolutionary thought, would permit that agents of Trotskyism, about whom we do not have the slightest doubt that he is an agent of imperialism, to publish a newspaper which copies outright the program of the Fourth International. By doing this, the Fourth International committed a real crime against the revolutionary movement to isolate it from the rest of the people, to isolate it from the masses, when it contaminated it with the stupidities, the discredit, and the repugnant thing which Trotskyism today is in the field of politics. https://wordsmith.social/protestation/quotes#quote7872
