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.
The states contributed to rising inflation following the revolutionary war by "printing their own money," since this was before there was any system in the US that mandated a single, solis currency.
The answer you’re looking for I believe, is Commerce.
The answer is D. Hope you like me and want to be friends on here!
