Look up whataboutism, the "tu quoque" fallacy, and the fallacy of moral equivalence.
Anything less is just a failure to understand basic ethics. You can call anything a fallacy - the idea that Americans have a higher moral authority on the subject of human rights is just ludicrous and worthy of a great deal of ridicule in light of the statistics of "Americans killing other innocent people for fundamentally racist/bigoted reasons" .. the real fallacy is that the American people think their nation has a 'right' to act with moral authority over any other nation. They really, really don't.
