Exactly. And I would add that the shitty things about regime in Cuba are somewhat contiguous with the previous shitty (Batista) regime. Both repressive. Both awful. The biggest appreciable difference is: American vs not-American (former Soviet) control/domination.

I think Obama at least sensed that the best way to get Cuba into a more functional state and better neighbour was to take the "but we're embargoed!" excuse away from the regime there. Trump undid that.

BTW the only time I came across sex tourism in Cuba, it was indeed a creepy guy with two young (probably minor) girls. In a cafe in Havana. But the guy was not Canadian, he was American. And repulsive.
