US pledges 'complete co-operation' over Okinawa alleged rape John Roos, the envoy to Japan, sought to reassure people on the southern Japanese island, where the US has a military base, that he shared their anger over the incident. "Not only me as a United States ambassador, but the entire United States government including our military will continue to work our hearts out to earn the trust of the Okinawan people and the people of Japan," he said. Okinawa governor Hirokazu Nakaima, a vocal critic of the size of the vast US presence on the island, met Defence Minister Satoshi Morimoto and expressed his fury, describing the alleged crime as "insane." Citing another case of sexual offence allegedly by a US soldier in August, the governor said: "This is nothing but abhorrent. "We cannot accept this, no matter how much (the US military presence) is claimed to be necessary for national security," he said. Prime Minister Yoshihiko Noda added that the alleged crime was "intolerable." The arrest of the two men on Tuesday is a potential flashpoint in relations between the US military and their reluctant Okinawan hosts. Previous criminal incidents have sparked angry, large-scale demonstrations, with participants demanding a trimming of the US footprint. Around half of the 47,000 military personnel Washington has in Japan are based in Okinawa.
