After all, when the war started, it wasn’t Lincoln’s intention to free the slaves. You know that. That was not his purpose in fighting the war. His purpose in fighting the war was to keep Southern territory within the grasp of the central government. You could almost say it was an imperial aim. It was a terrible thing to say, I know. But yeah, I mean, that’s what the war was fought for. Oh, it’s put in a nice way. We say we fought for the Union. You know, we don’t want anybody to secede. Yeah. Why no? What if they want to secede? We’re not going to let them secede. No, we want all that territory.
So, the Civil War and its aftermath, you know, have to be looked at in a longer perspective. And yes, the question needs to be asked also: yeah, is it possible if slavery could have been ended without 600,000 dead? We don’t know for sure. And when I mention these possibilities, you know, it’s very hard to imagine how it might have ended, except that we do know that slavery was ended in every other country in the western hemisphere. Slavery was ended in all these others places in the western hemisphere without a bloody civil war. Well, that doesn’t prove that it could have been ended, and, you know, every situation is different, but it makes you think. If you begin to think, "Oh, the only way it could have been done is with a bloody civil war," maybe not. I mean, maybe it would have taken longer. You know, maybe there could have been slave rebellions which hammered away at the Southern slave structure, hammered away at them in a war of attrition, not a big bloody mass war, but a war of attrition and guerrilla warfare, and John Brown-type raids.
Remember John Brown, who wanted to organize raids and a slave rebellion? Yeah, a little guerrilla action, not totally peaceful, no. But not massive slaughter. Well, John Brown was executed by the state of Virginia and the national government. He was executed in 1859 for wanting to lead slave revolts. And the next year, the government goes to war in a war that cost 600,000 lives and then, presumably, as people came to believe, to end slavery. There’s a kind of tragic irony in that juxtaposition of facts. So it’s worth thinking about, about the Civil War, and not to simply say, “Well, Civil War ended slavery, therefore whatever the human cost was, it was worth it.” It’s worth rethinking.
