The real question is how much the USA would have to pay Japan for Japan to take Hawaii. (Except for the naval base). The place is not culturally part of the USA and NEVER should have been made a state. For example: Most places in the USA if they have bilingual signs, the signs are in Spanish and English. In Hawaii they’re in Japanese and English. The hotels and shops accept Japanese currency (no doubt at a healthy discount). A significant percentage of the population wants nothing more than to subsist on welfare. The Hawaiians try (frequently successfully) to kill development that would bring income to the place.
Mexico could buy California and schiff could be part of their Govt.
It was a political and strategic purchase, from which to project our superpower reach, but has far out-lived its usefulness, now.
I spent 2 weeks there — 1 day on the “Magnum, PI” set, filming as an extra in the 1985 episode, “Little Girl Who” — and the natives hate us from the mainland.
