If the states were allowed to keep the weapons currently within their borders, North Dakota would roll.
The nukes are essentially useless, unless a true invasion occurs from a major power. Nuking a place you intend to eventually control is insanity, unless you never intend to enter the area for a few thousand years. Now, nuking the southern border, I can see. Run a Plowshares Program the length of the border using small nukes.
