Thank you for posing this very interesting question. I do not think Hawaii should become a sovereign nation. Hawaii relies almost solely on tourists; which come from other American states. When a U.S. state's economy relies directly on tourism, it would do it little good to break away from it's "customers" if you will, which are mostly American. It would be more difficult due to somewhat complicated security measures to vacation to a whole new country, and income from the central American government would no longer be giving Hawaii money. Hawaii doesn't really have much to offer other than the great tourist destinations in most parts of the state.
