@Radical_EgoCom @osmani Let's not over-simplify here, but however you define the current status of Cuba, it definitely is not in any position to decarbonize in any forseeable timeframe.
If you claim to need A to be able to do B, i. e. (not (and (not A) B)), then you would need to have NO instances of (and (not A) B), and it would help to have a demonstration instance of (and A B). But instead, you do have instances of (and (not A) B), and an instance of (and A (not B)).
