As we, Cubans, know (I was born there and lived there for more than a quarter of a century), the US embargo only affects the Cuban people. Those at the top, especially the ones part of Fidel's coterie (when he was in power), or Díaz-Canel's now, don't suffer the effects of the blockade. The self-imposed embargo includes a clampdown on freedom of speech, free press and a free judiciary. Fidel got rid of habeas corpus, because, why do you need the evidence if you're being tried by a "revolutionary" tribunal? It takes being Cuban or living as a Cuban for an extended period of time to get to know the real Cuba.
I want the embargo to end, if only so that we can see what the empero's been wearing all these years.
A point that very often escapes non-Cubans, is that If there hand't been an embargo, Fidel would not have been able to stay 49 years in power. So, from a political position, the blockade gave him the perfect excuse to stay in power for as long as he did.
