I notice people always respond with "but the US does this too!" and never actual incidents. No, I'm not going to just high five your vague head nod at wrong doing you can't even describe.

Seriously, sit down, make a list of incidents, including weighing the outcome of those incidents. If it's a case where an officer or a soldier did something wrong, list what happened after (court, punishment, cleared of wrongdoing, etc)

Then do the same for your favorite alternate country that you think is superior. If you want to pick team Iran or Russia, then lay it out for them. Make the same list.
