You know, there is a certain "Oceania has always been at war with Eurasia" tone here. Castro's regime is claimed to be progressive, and popular, and one of the few gems of light in a dark world. Castro's regime is also so fragile that Castro has no choice but to send dissidents to jail for decades and rig every election--for otherwise Radio Marti will hypnotize the people and lead them to vote it out of office.
One of the great victories of the Eurocommunist movement was to have gotten the western Far Left to commit to the priority of bourgeois emancipation--that freedom of speech, freedom of assembly, freedom to organize, and multi-party elections were key foundations without which nothing good could be built. It is curious to see such extraordinary backsliding in the interest of propping up an old dictator.
Lenin, after all, thought that the "dictatorship" part was temporary, until the state withered away and the government of men could be replaced by the administration of things. Castro thinks that the dictatorship is permanent.
