A passage in Lincoln's first Inaugural Address stuck out to me, and I wanted to see what you all thought of it. "Physically speaking, we cannot separate. We cannot remove our respective sections from each other, nor build an impassible wall between them. A husband and wife may be divorced, and go out of the presence, and beyond the reach of each other; but the different parts of our country cannot do this."
Lincoln is right that physically, the South cannot separate from the North. But most continents make up many different countries, unlike North America. I think the United States is way too big a country to work together cohesively, and the Civil War is an example of this. Why can't the South and the North split up? They would still need some sort of working relationship as separate countries, but I don't understand why Lincoln thought that just because they couldn't physically separate, they wouldn't be able to be two distinct countries.
