Cuba controls Venezuela’s communist Maduro. The Cuban communist protect Maduro but since oil is down the Cubans are not very interested right now since they can’t steal the oil and sell it for a profit. This is why Cuba is talking to Obama because there two cash cows are down and out(Venezuela and Russia).
Hugo Chavez was totally controlled by Casrto and when Chavez died the Castro’s had picked Maduro to take over. Castro was stealing so much oil and selling it on the world market which was paying for Cuba’s economy.
