I call this the finders keepers rule of colonialism. The western supremacists think that as long as you

• Kill a large enough percentage of the native population, and
• Wait long enough

Then the finders keepers rule kicks in, and you get to keep anything you stole. They even will yell “no ethnostates!!” at indegenous peoples they evicted and stole land from.

The main point is that its not for anyone but indigenous peoples to determine what they want to do with their land.
