The native Americans might have fared better with imperialism than with the colonization that they suffered. Imperialism, whatever else its sins, doesn’t seek to replace the entire population with its own, but only to dominate. Many nations survived imperialism, but everywhere that was truly colonized pretty much wiped out the natives.
Give the American Natives and the kingdoms of Africa tanks, guns, artillery, and vaccines (this one most of all) to resist imperialism.
