If Alaska or Texas wanted out, I say let 'em. Build a fence to keep them out of the USA. No money for schools. No military protection or treaties for joint defense. Tax the crap out of any imports or exports with them. Make any of their citizens who want to come into the US get passports and carefully monitor them to make sure they don't overstay their visas. Charge them for cable services, access to the internet, and of course we have shovel ready jobs building the fences and walls to keep them out of here.
