Wtf are you talking about. First Nations people’s have had this land collectively as sovereign nations for millennia its new that they only have their limited reservations. As US hegemony falls and ecosystems collapse they will only fight harder for their rightful land back. They are a great ally we have historically missed out on allying with. In terms of New Africa they have been an internal colony from the start, imported from Africa to work as slaves. They continue to be enslaved doing prison labor. They have fought for self determination from the start. From slave revolts to the Black Panthers to BLM. The ruling class has always been more scared by Black Nationalism than settler reformism. Socialist projects have always been decolonial from the USSR freeing the “prison house of nations” to China fighting Japanese colonialism, to Burkina Faso or Angola fighting against French colonialism, to Vietnam fighting French and US colonialism. The US revolution must be decolonial to, to right the particular wrongs of our horrible government and fight according to material conditions. Please go read the Red Deal or something like that.
