Not sure where you get genocide denial out of what amounts to “humans have been genociding each other since the Homo genus common ancestor split off”. I am asking if anyone actually expects any country on earth to decide that decades, or more likely centuries, in their past they conquered the land they now claim from another people group and now we feel bad about what our ancestors did so we are giving the country back to the most direct descendants of that group.
Are there actual expectations that the US is actually going to give everything or anything east of the Mississippi back to the native tribes, and/or Texas back to Mexico? Do we expect Canada to give BC back to their indigenous tribes? Obviously current relations with both groups need to be fixed because there are ongoing issues, nor should we celebrate the atrocities that happened during any of the colonial movements.
The Americas are also different from the colonialization of Africa, Asia, and the Middle East because the colonists moved there and stayed there instead of setting up exploitation of resources to send back, thus allowing “decolonizing” of those places to happen. And then decolonizing caused further problems by the colonizers drawing borders on their way out. This isn’t to advocate that they stayed colonies, nor do I think these places would have peacefully self-assembled into their own countries if Europe had just dropped everything and left. Human nature would have still had different land and resource wars happen as the native populations filled back in the power gaps.
Genocide is still as bad now as it was then, and even less acceptable because of our modern and “enlightened” morals. This applies to all ongoing genocides and ethnic cleansing attempts. I’m saying the cat is out of the bag on this though, and no government realistically fears any land back movement causing them to support any other country’s existence.
