edit: If someone is using whataboutism (as the person I'm responding to is) there is no real argument to respond to.
Any modern day atrocity can be justified by saying that it was done in the past by a different nation. Saying that the US had done something in the past to justify a different countries' present day actions is intellectually lazy and dishonest and is meant to shut down discussion. I was just not trying to waste my time typing this entire statement out but apparently some of you don't understand why `whatabout x` isn't a real argument.
