Karl Marx was in favor of socialist and communist-socialist revolutions, but he had a pretty nuanced view about it.
Noam Chomsky...a very terrifying aspect of our society, and other societies, is the equanimity and the detachment with which sane, reasonable, sensible people can observe [war and human suffering]. I think that's more terrifying than the occasional Hitler ...or other that crop up - these people would not able to operate were it not for this apathy and equanimity - and therefore I think that it is in some sense the sane and reasonable and tolerant people who should share a very serious burden of guilt, that they very easily throw on the shoulders of others who seem more extreme and more violent.
Noam ChomskyThe United States is a very insular society. Most people know very little about the outside world and don't care that much. They're concerned with their own affairs.
