Cuba has not been pulled or victimized by anybody. It is repeating the age old Latin American story from the time of Bolivar on.
The “liberator” comes ushering in a new world. Eventually, whatever the ideology that propels him to power devolves into “caciquismo” (cacique=indian chief). It happened in Mexico, Cuba, Uruguay, Argentina, etc. In the end it’s always one guy hanging on to power. You are seeing it now in Venezuela, Nicaragua, and Bolivia.
The cultural patterns in Latin America, I fear, are deep seated, and whatever the local/political/sociological mix is, the result is depressingly familiar.
It is quite a provincial and historically ignorant point of view to assert we had anything to do with Cuba.
They were going down the tubes even with massive infusions of Russian cash.
