Nah, the Cuban revolution is dead. Get ready for A. Further integrations with the capitalist US or B. Fall of the Cuban economy because they are definitely not getting support from venezuela which propped up their economy in the first place.
Cuba is basically an autarky, for all intents and purposes, so they're not going anywhere on that front, and I think Diaz-Canel will help to steer Cuba away from liberalism/revisionism. But I've been wrong before.
