North Dakota. Fourth largest nuclear power on the planet....
My thought, too. We also have oil and gas, coal, export electricity, and some pretty good export agriculture. I think we could even trade durum for some more exotic foods like bananas and citrus fruit. But we have food, fuel, electricity, livestock, even sources of salt and sugar. We'd be good until threatened, then unleash the dogs of war.
i agree, since we are the only state with an intentional by-pass, no other state would even think about us until late in the war. We have our own state bank, state grain elevator and an ecomomy in the black. Texas sounds like a great pick, but everyone else knows that too so most likely the other states would gang up on Texas from the start.
