A rich man's son, Hatoyama has impressed Obama administration officials with his unreliability on a major issue dividing Japan and the United States: the future of a Marine Corps air station in Okinawa. Hatoyama promised Obama twice that he'd solve the issue. According to a long-standing agreement with Japan, the Futenma air base is supposed to be moved to an isolated part of Okinawa. (It now sits in the middle of a city of more than 80,000.) But Hatoyama's party, the Democratic Party of Japan, said it wanted to reexamine the agreement and to propose a different plan. It is supposed to do that by May. So far, nothing has come in over the transom. Uh, Yukio, you're supposed to be an ally, remember?
