So first Land Back is an international movement; not exclusively US-based. It's a very simple premise: restore indigenous land stolen through colonialism to its rightful owners (indigenous people).
As for what this looks like in practice that will vary wildly as it will depend on what each tribe considers sufficient recompense for the injustices done to them.
This process is necessary for proper decolonization and as socialists it will be required of us to coordinate with indigenous groups on this issue, giving them the expected deference in resolving the matter to whatever extent they find agreeable and is within feasibility.
