There was something I watched by noncompete and Luna oi on Marxist morality a few days ago. Alot of this is hypothetical and simply is not the materialist conditions. Discount at least 68 million of the 300 million Americans who would prefer facism, we also take into account military and such. And if the United States is truly facist then they would have no problem wiping any open rebellions of such a kind off the face of the earth no matter how many civilians were caught int eh cross fire. They're willing to let 600k of their own citizens die from a. Disease.
Then we also have to take into account nato and it's allies alongside the un who might leader a counter revolution ala the white russians. People would say war communism then, but then you just lose all t of the people who's ideals find such a thing repulsive.
And if we were able to somehow defeat this counter revolution still (and since the material conditions have changed drastically at this point most likely) how would indigenous rule be done? If we took into consideration the entire native population (this also take into consideration mixed) of both Canada and USA we have 6,894,359 In total with a population of in the us (discounting said number above) of 324,554,922. Now if we add both numbers and using the percentage provide by the census for the us of that number 204,172,757 is white.
Now that same video series also stated that essentially for every John brown there's 2 million who won't side with the oppressed if it means giving up privledge, and it should be pointed out that a not so Insignificant population of non white would also not want to return land to the indigenous.
Now with this known how would governance be done? People say self determination but by a minority of a minority? Even if it's a justified double standard itself would eventfully collapse as more and more people inevitably want a say in the way things are done as the generations go.
The ideals of SUCH a decolonization just do not met the material conditions required for such a venture.
