FILE - In this Aug. 14, 2012 file photo, a U.S. Air Force F-22 Raptor stealth fighter takes off from Kadena Air Base on the southern island of Okinawa in Japan. China is trying to strengthen its claim on tiny, uninhabited, Japanese-controlled islands, Senkaku in Japanese and Diaoyu in Chinese, by raising questions about the much larger Okinawa chain that is home to more than a million Japanese along with major U.S. military installations. The tactic, however, appears to have done little but harden Tokyo’s stance. (AP Photo/Greg Baker, File) less
