Proofs ?<quoted text>
When U.S. handed Okinawa back to the Japs, they gave the Japs the right to use the Diaoyu islands, not sovereignty, which they said should be worked out between Japan and China.
Why would the US wants to excercise her Navy with Japan for the surrounding Diaoyu Islands
You do not know about Japan/US WW-2 Pacific Treaty that Japan can not grow or build up her Arm Forces and all will be taking are under USA's, that treaty helped China to get rid off Japan Empire in the Pacific region, now China started invade the Pacific by creating new U-Shape Sea-Border surrounding Paracell and Spratly all the way down to Thailand.
Ain't do the job, China, ASEAN will not let you do that, even some Chinese experts already mentioned that is a self-kill to China
