In Japan, Prime Minister Yukio Hatoyama has resigned over his broken promise to move a US military base off the island of Okinawa. Hatoyama sparked outrage last month when he decided to relocate the base to the north side of the island, as originally agreed upon with the United States. Local residents opposed the move, which came just weeks after some 90,000 people held a rally to call for the base’s removal. Half the estimated 47,000 US troops in Japan are stationed on Okinawa.
