Yeah, but it's ridiculous that you couldn't get the peaceful reintegration, it just mucks up the story that way.
Eh, it happens. AI is AI, and it's not like I could set it to behave a certain way in that scenario.
I'm sure if I was bothered to, I could come up with a plot reason for it happening, but I'm not. I do like to think about how weird the inevitable American/Franco split in ideaology is going to be down the line in that world, but that's it.
Also, completely minor quibble, but they've given the CSA Generic "Infantry Equipment III" again as opposed to anything "unique". As someone who hates the "Generic" tech pictures, this makes me very sad.
