Only wishful thinkers GenZ, pro cubans Biden's functionaries will rule out Russia's or Chinese directed attack with the authorization of Castro's dictatorship. They are explicit enemies of the U.S, allways conspiring and spying against it.
In Cuba if you fart, the CDR, UJC, PCC, MTT, FMC and several other communist organizations to control the people will know and assign spies to you. The USA embassy in Cuba is the main target of the Cuban intelligence and has spies all around the buildings and where the functionaries live, what they ate, who they talk to, what they poop, everything!. They are constantly been watched by the cuban government. Do you really think this will go on unnoticed?
