The current government tend towards ‘truth and reconciliation’ is an attempt (or at least a gesture) to investigate and rectify these wrongs and treaty violations.
I’m sure the same holds in the US in areas where there was not a wholesale genocide.
I only say that to caution advocating for other countries to adopt the approach Canada has taken. I am of the view there were a lot of classic examples of well intentioned policies with disastrous results.
At the same time, I don’t know enough about the issue to offer alternative policy without worrying about the sensitivity of the issue.
The logic of ‘conquest->hegemony’ does not quite work in parts of North America because the ‘conquest’ was not a traditional one, but rather because of duplicity and breaking treaties, which- in a rules based order- typically have methods of restitution.
Parts of the USA, like the Russian conquest of Eurasia, were traditional conquests where the invaders drove out the inhabitants by force, but that is not a universal narrative in the European colonization of North America.
