"No, I said 'unilateral' to apply to a situation where only one side of the situation had any say in the matter."
And THAT's completely wrong. The one side you were refering to isn't one entity, it's multiple. Good lord man, we can't discuss this if you can't even grasp basic concepts.
Really? The southern states left the Union without discussion, walking away from treaty obligations entered into by the country as a whole, appropriating whatever federal property they could get their hands on, and repudiating their share of the national debt. What say did the remaining states have in any of that?
