You mean "wrest control of the oil and gas from the CIA", right?
That shit's complicated. One side fought for the state's rights to self-govern, and at the center of that debate was the right to own slaves. The other side fought against the state's rights to self-govern, and at the center of that debate was fealty to the federal government.
Both sides were right. Both sides were wrong. The US South's history will be forever blemished with the institution of slavery, and most people arguing of the nuances of the debates have zero clue why there is even a debate outside of the slavery discussion.
Well, knowing what we know now of the backgrounds of the owners of many/most slaver ships, as well as plantations, it should be obvious what was being planned all along. Slavery wasn't really the issue for Lincoln, it was the people behind it, and what they were doing to the country with it.

Do a search for Lincoln. It's an eye opener.
Laws against slavery were not on the books until 2 whole years into the war. The war wasn't fought over slavery. It was fought over fealty to the Federal government. Slavery became an issue/platform for recruitment for the North after the war was raging for 2 years.
You can watch this vid and try to pick it apart all you want, but the conversation itself complicated.
