How many war crimes has the US committed versus SA? I don't think SA even gets to the US toes, it's just that genocide, political overthrowns, invasions, and what not are normalised and are okay when the US does it, but when another non-Western country does it is showed with 10 times the strength.
US is not very far away from being so religiously fanatic, they have almost zero women's and LGBT people's rights, there's rampant racism and xenophobia, I don't know what news or history books you read but the US is absolutely on no moral ground to tell SA they are somewhat better.
It almost seems as if there's some kind of islamophobia here... Mmm, no, I'm sure US good and SA bad.
