The Cuban Revolution is generally viewed positively pretty much everywhere, except for the land of the sponsors of the previous regime. America has a huge problem with chauvinism, even among self-described liberals. I just read rant from a conservative-hating Democrat calling for sanctioning Russia to oblivion and intervening for an independent Chechnya. Rambles like these approach Ann Coulter levels of insanity. Although I personally don't like Sanders much, his candidacy might be on the long term a useful way to gradually reject some of the most extreme Cold War taboos.
