What I wrote in the previous mssg is not negated by Japan's use or non-use of air superiority a/c other than the F4. It also does not change the fact that the US is NOT going to give Guam to Japan nor is the US going to cede military defense of the island to the Japanese.
Rather than read sonmeone else's drivel, why not visit Japan and see the US occupation forces. There are bases everywhere. You will need a visitor's pass and an active duty sponsor to get on the base. After 9/11, I suspect that a more rigorous checkup may be required. I have only been on the mainland, never to Oki.
Besides, Oki was bought and paid for w/ American lives. Additionally, the talk of "giving Oki back to the Japanese" has been circulating since at least when I lived at Yokota AB in 69-71.
