Are states the only sovereigns with this power? What sort of process is required for them to exercise it? Can a governor simply declare it? A state legislature? Does it need to be voted on by the people? Are you just making this up as you go along or is it codified somewhere?
I suppose making it up as I go along, sort of like the Union did.
