Clumsy Political Propaganda, Oliver Stone Style
The adulation this film received in the 80s was ridiculous. This is strident commie propaganda. Oliver Stone would make a great Propaganda Minister.
The reality, the US simply could not allow another Communist regime in Central America, one year after Nicaragua. This was the height of the Cold War, and there was a hell of a lot on the line.
Carter didn't get it, and in his naivety, he emboldened the Soviets. Reagan got, and brought the Soviets to their knees.
End of story.
