I don't know, but I hope the USA puts the CSA through an alternate "Reconstruction" which beats them down and breaks their will, breaks them forever.  I like the wry humor Turtledove interjected that they call it the "Freedom" Party; of course, no one THINKS they're "bad", and the States' Rights and Pro-slavery groups during OTL Civil War THOUGHT they were just new revolutionaries (admittedly, they weren't the ficional character Jake Featherston).  Nonetheless, I keep thinking of the end of Drive to the East, where Pittsburg/Stalingrad is finally wiping out the CSA army, and two CSA soldiers are just going on about how it's about "Freedom" and their right to not have the US tell them what to do;  dude, they wiped out the south's Blacks in an alternate holocaust, nerve-gassed thousands of people in Ohio, etc. etc.  I'm glad that Charleston (were the secession started) wound up as ash floating around in the atmosphere.
