Cool, yeah, more bad stuff. Doesn't cancel out what I was talking about at all - this is just a standard "whataboutism". I'd like to see an end to all bombing everywhere. It's easier as a Canadian to hold this perspective, of course; I don't have to condone or defend the past evils of America at all.
Whataboutism has its merit in this instance. If the U.S wants to show its moral superioriry it needs to actually try becoming morally superior. Which I am not sure it is. Otherwise it reeks of hypocrisy and people rightly suspects most Americans do not care about China's morals at all but about losing their hegemony to China. So its easy to become a cynic when seeing these debates.
