Cuba Explained, by David Archibald.
The Castro regime is involved in the ongoing destruction of Venezuela and what has now become a calibrated genocide and massive refugee exodus. They are willing to go to extremes to remain in partial control of Venezuela because that’s where they have been getting most of their income. Therefore the dictatorship’s survival hinges on whether they can get the genocidal regime in Caracas to survive. They have good odds because most countries really don’t care when communists are murdering people.
