Or simply make Okinawa an independent state, if it wanted to (with a defense treaty with the United States, of course). That was probably feasible, too.
That's possible. Post-occupation US-Okinawan relations though would be quite problematic. Okinawa being a part of Japan means that Tokyo gets at last a share of local grievances while local authorities are powerless to do anything. However, in the case of independent Okinawa you would have an actual national government causing troubles there, even if the US had negotiated/forced Okinawans to sign water-tight treaties on stationing of US forces there.
