Prudent remarks on Castro by Sanders?

First, the remarks you refer to were made 35 years ago. And Anderson Cooper brought them up, not Sanders. Just to be clear.

Here was his response:
[quote]“When Fidel Castro came into office, you know what he did? He had a massive literacy program,” Sanders said. “Is that a bad thing, even though Fidel Castro did it?”

Cooper noted that Castro’s administration imprisoned dissidents.

“That’s right, and we condemn that,” Sanders said. “Unlike Donald Trump ― let’s be clear ― I do not think that [North Korean leader] Kim Jong Un is a good friend. I don’t trade love letters with a murdering dictator. [Russian President] Vladimir Putin: not a great friend of mine.”[quote]Sanders told Cooper that he’s “very opposed to the authoritarian nature of Cuba,” but said it’s “unfair to simply say everything is bad.”[/quote]

Cuba [i]does[/i] have a better educational system. It has a better healthcare system. It's also communist. Sanders never implied the Cuban revolution was a great thing - he said nothing is all bad.
