After the success of the revolution in 1959, the rebel leader Fidel Castro began to consolidate political power, and associate with communist officials.
According to Castro, Batista was a "monstrum horrendum ... without entrails" who had committed an act of treachery in 1933 when he initiated a coup to oust Cuban president Ramón Grau.
[7] At the time of the revolution the 26th of July Movement involved people of various political persuasions, but most were in agreement and desired the reinstatement of the 1940 Constitution of Cuba and supported the ideals of Jose Marti.
[9] In a speech delivered in April 1959, Fidel Castro announced the postponement of the elections promised, which were scheduled to occur after the overthrow of Fulgencio Batista.
[16] In the immediate aftermath of the Cuban Revolution, José Miró Cardona was appointed as new prime minister, only to resign and flee to Miami.
While in Miami, Cardona wrote in the magazine Diaro de la Marina that the Cuban Revolution was a much needed progressive force, that should not ignore the poor of Cuba.
[17] Throughout 1960, many articles were published in the socialist Monthly Review journal, arguing against any rumored "betrayal" of the Cuban Revolution.
[20] Draper considered his betrayal thesis to be a criticism of the accounts of socialists like Paul Sweezy and Leo Huberman who were sympathetic to Castro.
Draper attempted to present a Marxist interpretation of Castroism, that made analogies to Trotskyist conceptions of Stalinism as a betrayer of the Russian Revolution.
[20] On April 3, 1961 the Kennedy administration releases its "White Paper on Cuba"; a document authored by historian Arthur M. Schlesinger Jr.
The contents detail communist influence in Cuba, and accuse Castro of betraying the promises of the Cuban Revolution.
The militant group valued the progressive nature of the Cuban Revolution but argued it had been "betrayed" by Castro's undemocratic turn.
