The CIA wants me to believe this like they want me to believe Putin wears a diaper.
China is in a position to help if no one else if Cuba is on the skids.
The Chicoms have invested pretty deep into Venezuela no reason not to do the same in Cuber.
There was a report last year that China had been contracted to rebuild Cuba’s train system (which is in about the shape you can imagine it is in). So yeah, there is a risk that the Cuban regime gets propped up by whatever power wants to use it as a FOB against the US. So it would be good to cultivate some sort of alternative to the Cuban government. Perhaps a coalition of Cuban-American leaders could put together a plan for seeing Cuba transition to a market economy with elections, and then infiltrate the plan into Cuba itself.
