USA is not involved in Cuban politics since Fidel Castro took over. If they are problems in Cuba they are Cuban madeIts called controlled Chaos. 70k+ Pakistani citizens dead over the course of the American WOT is a case study.
Maybe Cuba and Haiti are in a mess due to constant meddling of America in their affairs? Ever thought about that? Its rather strange When America is trying to meddle in south China sea, around China's backyard, world is seeing , out of blue, the unrest in Cuba and Haiti, places you call American backyard. One word, BRI.
I am sure you old enough to understand the geopolitics.
