A lot of Americans, even those who supposedly hate America, still have an intrinsic belief that we are justified in going to war with "the bad people". They understand that America is bad, but clearly the other places are worse, and so it's our duty to put them in their place. This is why watering down anti-American sentiment is so dangerous. American leftism is littered with home grown propaganda, and the state will tap into it any time it needs to manufacture consent. If it needs you to agree that a place needs bombing, it will just convince you that place is super totally "authoritarian".
