I don't think the US would allow a Confederate Victory by quagmire or whatever,
ok,
A: the USA has no intention of even letting them talk about secession.
B: Most confederates are unlikely to rebel, they lost two wars in a row, and their country no longer exist.
By no I think they know the effects of Radiation.they'll use everything in their article including nukes to make sure the Confederates don't win, of course nukes are a last resort,
nukes would not be an option
Yes, ok.but now that they got the place occupied, its hard for me to see a convincing argument for them to let them go their seperate way, and also I think some southerners have a conscious, they are probably haunted by the spectacle of those death camps, some people down south might wonder if a revived CSA was a good thing, if it means a return to the likes of Jake Featherston or somebody like him for instance. If they integrate with the USA and get their voting rights back, they can influence who gets elected President and pass laws with their congressmen and Senators.
may take years before a southener gets elected to the white house as president, but ok.
When you consider that Jake Featherston made a lot of Confederate citizens "disappear" without trial or jury, many would no doubt think they were better off under US rule.
that's one terrible president out of how many?
The Canadians on the otherhand are just occupied, they understand why, but now that the reason (the UK alliance with the CSA) is no longer valid, they probably want their independence even more, and probably want Quebec back as well, and some "mealy mouthed liberal" just might grant them what they want, think Jimmy Carter and the Panama Canal treaty for instance.
See, Canada is more likely to rebel that the former confederacy.
