I'm arguing that the largest criminal is not qualified to police the next-largest criminal.
The US has no moral authority when it comes to illegal invasions and murdering innocent people. Period.
If you want to do something effective about criminal, illegal wars - jail your own war criminals. Ukraine has plenty of them, even prior to Febuary 23rd. You did nothing effective about them, and thus the mess you are in.
Anything less is hypocricy and moral grandstanding.
