I look at the civil this way that wouldnt be revionistic or contrary to either north or souths goals or intentions. The union you could say was more socialist and nationalistic due to a stronger and effective government beneficial for the nation, the union side also had many leftists fight along their side against the confederacy to help free the black slaves, even the socialist fighters in the spanish civil war against the hitler backed regime had a paramilitary company called abraham lincoln brigade, you can say kind of that the american republican party has roots in what today we would recognize as socialism.
I see the confederacy as libertarian capitalists because they secceeded from the union to form a smaller government called a confederacy because they were afraid that the federal government was gonna infringe their personal libertarian right to own slaves.
In a way, the union victory in the civil war I see it as a victory against a selfish capitalist libertarian greedy entity.
