According to Cairo Declaration and Potsdam Declaration and the surrender agreements signed by Japan, Okinawa is not a piece of Japan territory.<quoted text>
Yeah, and trying to claim Okinawa too is just silly. It's like looking for any excuse to start a war.
It is a piece of territory wrongfully occupied by Japan imperial govt and therefore must be returned to its owners upon Japan's defeat and surrender to the victorious Allied Powers.
Japan and USA violated these international agreements and declarations later.
