It doesn't really matter whether America or any other country gets it right. The entire point of the "tu quoque" (appeal to hypocrisy) rhetorical tactic is derail the debate and get people defensive, instead of focusing on the actual problems.
The United States has a long list of historical human rights abuses, starting with the legacy we inherited from Columbus of enslaving and murdering the local populations and continuing up to a laundry list of problems we still have today. They were wrong at the time, they are wrong now, and we should really work to not keep committing large or small scale atrocities, and redress what past crimes we can.
But that doesn't change the wrongness of other countries human rights violations, and doesn't mean that they shouldn't stop what they're doing and redress what they've done. The US or every other country being wrong doesn't give them a pass to be wrong also. We shouldn't wait for one pure leader of one untainted country to arise[1] and call us out on our actions before we repent.
