You say:
> There is no 'right' and 'wrong' side of history.
But then you conclude:
> There was a lot of cruelty, bloodshed and lies. [...] The US could certainly have been much worse.
So you do accept there's a gradient of right and wrong.
> The US could certainly have been much worse.
But also a lot better!
> But there has not yet been anyone in history who avoided that while being large.
What we've seen is next level. This is due to the increase in mobility and world trade, sure. But it has been abused heavily, and seemingly to every extend possible. I dont know how it could have been worse without being a straight up dictatorship. (having only two parties come very close to being a dictatorship if you ask me; only one party better than the China the US like to bash so much lately).
> They've pushed science and the arts forward, promoted freedom as a cultural aspiration rather than rule by a monarch and generally acted as a credible supporting force for the greatest improvement of living standards the world has ever seen in Asia.
Tell that to the Vietnamese and North Koreans. Indonesia and Philippines also have a bit of a US hangover.
Science is fucked nowadays. Very "proprietary", as by the US-push patent law.
I think there is right and wrong. Read some Jesus and you know that ideas of what it good behavior and what is bad is not at all new. I'm not religious, but just to show that it is not merely the last decades that we know we should be nice to people and now do any horrible act for a bit of profit.
