Could the U.S.-Japan alliance founder as a result of alcohol? Apparently. At least, that's the implication of the U.S. Navy's ban on drinking by its personnel stationed in Japan. It would be far better to phase out America's military presence in Okinawa, turning U.S. bases back to the Japanese government. More than seven decades after the end of World War II, Tokyo should take over responsibility for Japan's defense.

Washington currently maintains 85 military bases and some 53,000 troops in Japan. Roughly 40 percent of those facilities, half the people and three-quarters of the base area are located in Okinawa, with just 0.6 percent of Japan's land mass.

Local anger exploded in 1995 after three American service members raped a 12-year-old girl. The Japanese government sought to placate islanders with financial transfers and plans to move the Futenma air base and relocate U.S. Marines to Guam. These schemes failed to satisfy, however. Base opponents, bolstered by the 2014 gubernatorial victory of Takeshi Onaga, continued to resist. Although the national government pushed ahead, Onaga attempted to revoke the necessary building permits.
