John Quincy Adams was the successor to President Monroe who broke the grasp of the Virginia Dynasty.
I would most possibly do the same thing, or take the south back to US as brothers, but I might also add a little punishment. The punishment would be limited import for a period of years (1, or 5). I would also not allow them to vote or participate in any political meeting, congressional decisions, etc.
Hope this helps, you might have a different opinion however, but as I think, it would be better to punish them for
1. Not obeying the rules (still having slavery)
2. Electing a secondary president.
3. Helping the war happen.
4. Trying to become independent from the rest of US.
