They won't be Americans. They will occupy the new reservations, except the "Injuns" are civilized now so they don't have to live behind barbed wire, the Reb savages do.
America is very very nasty to people Americans don't like.
I know you want to do an epic dunk on America or whatever but your repeated assertions that the US would reenact the Indian Removals post-1945
and with a bleeding-heart socialist party in power half the time are laughable.
On a wider note, I think your haunting this thread just to refuse to engage with the OP's work on its own terms and shit on Turtledove's work continually in a thread that's
fundamentally devoted to it and that's not going to change is mean-spirited. We get it, you think "Turtledove's timeline is shit and boring" (in your own words) and you're welcome to think that, but this thread is already about Southern Victory. It's not gonna become a Years of Rice and Salt thread, or a Man in the High Castle thread. How is it kind or constructive to fight over the same fictional stipulation this TL is based on for over a dozen pages?
