And we're also better off for the US not invading Russia, North Korea and Iran. That is what was so suspicious about the US Civil War, the US is traditionally fairly heedless of terrible things happening unless it smells an economic benefit from being involved. The traditional tool for ending slavery has been prosperity. That worked pretty much everywhere it was tried - including North America. Armies are not a tool of creating prosperity, so it seems a bit suspicious that this was the best path in the Southern US. Obviously the States gets to sort itself out with no involvement from anyone else, but it is a very open question whether holding itself together was the best choice.
