Ultimately sanctions have never worked, they always punish the innocent over the empowered, and in this particular case it shows that there's a hell of a difference sanctioning a small isldnd like Cuba or someplace that 'globally is irrelevant' to trying to sanction a commodities 'super power' which is interconnected to everything.
