I was working construction in the 80's in Florida. Most of the dumptrucks hauling fill to me were driven by Cubans. A great many of these were told once, To go and were led to the Gulf of Mexico at gunpoint. Many if not all of these people had been locked up in the Cuban prisons. The were forced to leave so that the populations effect on the value of currency could be balanced by removing Undesirable people, From the demands on currency. The news reports of the Mahriel boat lift counts the refugees to be 124,000 people. Making it. It is unclear how many drowned trying. You see the boats were anything that floated. They were refugees not of war. But of failed economic systems for currency valuation. This is my opinion. By the way a lot of these past criminals, Were good hard working people that were fairly easy to work with even, While we spoke different languages. The arguments and heated disputes of the truck drivers, I personally watched one day while the topic of Fidel Castro came up. Even after they were forced to leave Cuba, Some of these people were convinced he was a great leader. I would suggest he failed those people as a leader. But he kept the value of his currency high and let America save his unwanted people.
So , I for one do not really care about Fidel Castro or his opinion, But I would say it would be encouraging to hear that his brother was interested in reducing global warming and worries about hazardous waste issues. By the way currencv valuation is a problem we can solve together but human rights are also an important topic.
