Page "Fourth International Posadist" Paragraph 5

The Posadist group was accused by Soviet-friendly forces in Cuba of arguing that the Cuban government should forcibly expel the American military base at Guantanamo Bay and of trying to organise workers in the town of Guantánamo to march on the nearby military base.

That was taken as a justificiation by the government for imposing a ban on them, Castro denonuncing their influence as " pestilential " at the Tricontinental Congress held in January 1966.

Cuban Posadists went on to claim that Castro had Guevara killed when, it turned out, he was actually in Bolivia fighting with the guerrilla movement there.

Conversely, after Guevara was executed by Bolivian authorities, Posadas claimed in 1967 that Che Guevara wasn't actually dead but was being kept in prison by Castro's government.
