Why are these populations hostile?
What are you implying? That hostility can be legitimated historically and then the targets of hostility have to submit to it?
Please be realistic and acknowledge that everyone seeks a peaceful existence. No one can be expected to submit to hostility because their ancestors did things to warrant it.
Everyone's ancestors have sinned against others. It is the nature of existence. Anyone who pretends like their ancestors were free of sin is lying. People have enslaved, abused, and exploited others since before humans were a sentient species. We should be trying to solve it, not perpetuate it by blaming and attacking others.
