lcpiper, your initial statement was about groups holding separate, yet politically manipulating other groups to influence the actions of the other groups, to include via infiltration.
My refutation was that the European powers really did not care about influencing the natives. They worried about enslaving, disposessing, relocating, or eradicating the natives. They were not worried about influence.
Had the natives wished to peacefully assimilate, they would not have been able to do so.
Those groups that tried, were abused anyway.
Those groups that took a half-way approach, and signed peace agreements, were double-crossed overtly by the federal or state governments, or covertly by corrupt agents.
Just look at Arizona, where Tucson area ranchers diverted the river, starving out agriculture in the Phoenix area for the Pima and Maricopa.
Your premise is flawed, in all the incarnations you have tried to give it in this thread.
