That's still being conquered. It's part of being conquered. The first Nations aren't the first or last people to sign treaties and agreements with more powerful group that were never honored. I hate how myopic people are about history, assuming their suffering is special, within human history.

The shit the Golden Horde did across Asia and western Europe, only a couple centuries earlier, is equal to if not more horrific, like completing multiple genocides in the process, then breeding their DNA into the entire fucking human species through decades of mass raping across continents.
