This is a very sensitive topic as i am not cuban and therefore have no first-hand experience of the situation there. I was watching a video on cuban democracy by comrade azureScapegoat and it was good, good video but then i watched the comments and while many of them were supportive and complementing cubas democratic system, there were some self-proclaimed "born and raised in cuba" cubans who would tell stuff like the "the municipal assemblies has no political power, its all in the hands of the communist party" and "not true, i am born and raised cuban and can confirm that this is not true, cuba is one-party and therefore totalitarian" the "one party= totalitarian" is bullshit but i can understand why struggling cubans would fall into the myth of totalitarianism where basically anything that does not have atleast two neo-liberal parties is considered Nazi-soviet-Reich-empire 2.0. Its just sad to be honest, i understand why cubans might give their government the fault regarding the misery the US puts them in and i just hope they wont loose their revolutionary spirit. America will torture and haunt cuba until eternity until the people's revolutionary spirit is broken and they will return to being a casino and brothel dominated sugar colony. I hate the US with every cell in my body for spending so much of its valuable resources and money into worsening people's conditions and life quality from countries who do not obey its order. Im sick of it and the cubans and every country trapped under the boot of this lump of corporate oligarchy hidden behind a thin veil of governance deserves better. The day will come where the american empire will be served justice and the world will be free from its chains. I can just wish the cubans to stay strong and to keep conscious about the US' role in modern geo-politics and how it keeps poor countries poor so they obey their master. Same goes to people in every socialist country and more generally the global south.
Don't you think there's also a sense of betrayal? It seems to be often the case in Russia with regards to USSR. People feel they've been "led astray" by the socialists, who only ever wanted power. And this idea is seemingly supported by the number of party and Komsomol activists/officials that went on to be oligarchs and/or government officials in the current capitalist federation
In your case top leadership betrayed the idea of socialism and communism, common in 1989 CPSU condemned Molotov pact, gave back the baltics and so on... Gorbi phoned Reagan and called US the best friend. In our case the top leadership was socialistic but it was the people who were fed up of constant violence in the state. Violence happened due to ultra left parties/Maoists who started murdering our cadres and peasants and the grand effect of media. The media propaganda was totally against CPIM in it's last years (they were never pro CPM) . Also after 2013 India got nazified along the lines of Hindutva. Most hindu bengalis are now staunch supporter of fascism. So, the bourgeoisie parties radicalized the muslim population to betray the communists and Hindus after all the violence and media propaganda chose hindutva politics. That's how CPM never came back post 2014.
Thank you for the context
