A lot of things. In the past century USA had plenty of "no blacks" signs around, Operation Barrel Roll happened against a neutral country, so I doubt USA have the moral high ground you think it has.

If we specifically refer to the past decade though, it looks much worse for USA.

I’m still waiting for those well sourced numbers I asked for.

Again, I’m not making any excuses for the USA, though you seem insistent on believing so. Two things can be true at the same time: that the USA has been a destructive world influence and contributed to much suffering, as well as China having killed an astronomical number of its own citizens. Both are bad, China is worse, full stop.

And why move the goalposts to the last decade? That’s like excusing Bill Cosby because he hasn’t done any raping lately.
