I would ask you to name a single instance where the loosing side of a rebellion suffered less and was incorporated back into the government faster than the southern U.S. states.
Germany and Italy after WWII. All countries suffer after wartime but the south was punished horribly by the radical Republicans - bringing a lot of graft and corruption to the states as well. Hey, I’m from the state that voted not to give RE Lee’s citizenship back to him after his request was found about 30 years ago. Liz Holtzman - I mean you! That kind of sums up the idiotic attitude of some northerners.
I think it would have been better if Lincoln had lived. Johnson was rabid.
