I mean, yes? And while in a better world we'd have proper solutions to that that would render unto these various peoples the land that was unjustly stolen from them, that is neither practical nor realistically achievable (undoing everything done to America and sending all Americans back to the various places they came from is quite a logistical undertaking, and we've decimated the various native populations to a degree where re-settlement would take quite a long time). Fortunately the vast majority of exploited peoples, Palestinian and otherwise, share a commonality with the vast majority of the rest of humanity; they don't want revenge or domination, they simply want to exist free of oppression, which is quite a bit easier to do (though not easy thanks to entrenched settler supremacist ideas worldwide).

So, stop spreading propaganda that they're inferior, stop excluding them from the halls of power, let them participate in determining the destiny of their societies, give reparations, etc. etc. I don't know if these things will be enough for all of these groups, they were harmed in different ways and the wounds are in different states, but it certainly beats what we've done so far, which is status quo while endlessly debating it.
