What we, as a country, have done and continue to do to Cuba is absolutely unconscionable.
It affects us too. Over the last 60+ years there have hundreds of thousands or even millions of Cuban migrants to the US. This [1] claims 2.7 million but includes US-born descendants. Cuban migrants aren't a random sample of Cubans. They skew very much anti-Castro, which means by extension they skew very pro-Batista. Definitely right-leaning or even pro-fascist [2[.
Importing fascist or fascist adjacent people who ultimately became voters has changed US politics where Florida is now a safely red state. Here's more on the demographics of Cubans in Miami in particular [3].
I find it interesting how this aspect of immigration is so often missed or glossed over.
There is absolutely no justification for continuing 60+ years of sanctions just because our puppet was deposed.
