None of this would be happening if some “rogue element” had taken out the Castros and Chavez! We can only hope that the people of Cuba find a way to revolt!
as far as outside funding possibly true, but the underlying issues which get leftists into power in places like el salvador have a lot to do with local politics, and in my experience the mind-bogglingly blatant corruption of the traditional oligarchies/ruling parties, connected then to the abject poverty (not US-style, but dirt-floor-style) the bulk of the population concurrently enjoys.
