Some would point out the same before the Colonials came too. In the other examples it was all out war with promises of more, not treaties ignored when it became inconvenient or as bait to disarm.

There were also commitments made that are only starting to be honoured in some cases today.

It’s the atrocities from the higher standards of the “right God” Fearing and “more civilized” peoples that came to into replace everyone. There was no honour in it which was supposedly the basis of some of these societies They were supposed to be better often were not even for their times.

Unfortunately that’s a tale as old as time too…
