Exterminating the native americans was never the plan or there would never have been reservations...there would have been thousands of soldiers fielded and they would have been hunted until dead.
Apaches, Commanche, Navajo, Blackfeet, on and on...they claimed rights to take livestock, crops, and kill women, babies, and men as they wanted anywhere they wanted...laying claims to land occupied occasionally and seasonally and they chose to go down fighting. Columbus and the Spaniards were more responsible for many more deaths of indigenous populations than the US calvary, but academics paint a picture of rampaging murderous white men wantonly killing peacefull native men, women, and babies.Wearing US Calvary blue.
Estimations are officially 500,000 -1,000,000 from 1770s til recent times...but other estimations are in the millions. Like anyone really knows.
Of course the high numbers are usually accompanied by a disclaimer that most of those deaths were more likely from disease...again the White man's fault, like we invented them.
They had 300 years of choosing to fight, and living on borrowed time until history caught up to the outmoded nomads and limited primitive farmers.
And you compare that to stripping women and little children naked, encouraging them to crowd into small nasty cement rooms like cattle, and screaming as insect poison was pumped into the room while children screamed in fear and mothers cried until they drew a last tortured breath and suffocated in agony.
Then...force their relatives and neighbors to drag out their bodies, and put them into ovens to burn. And repeat...over and over...on and on, for year after year at camp after camp. Cheaper than shooting lined up families, in front of mass graves, bullets were costly.
This happened to people just like us, not too long ago, after they were taken from dinner tables and living rooms just like ours, for no reason other than Christian Germans thought it was a good idea.
Catholic, Jew, Romany, gay...time to be gone. You offended German sensibilities. And most of Europe jumped to help.
