“To what extent did Castro at this point conceal secret communist purposes? He later said that he hid radical views in order to hold the anti-Batista coalition together, and this was probably true. But, though a radical, there is no conclusive evidence that he was then a Communist or even a Marxist-Leninist. Whatever he later became, he began as a romantic, left-wing nationalist—in his own phrase, a “utopian Socialist.” He had tried to read Das Kapital at the University of Havana but, according to his own account, bogged down on page 370.”
