The Japanese government is on the verge of abandoning its historic commitment to pacifism. The current prime minister, Shinzo Abe, has made constitutional revision a major plank of his reform agenda. Coming to power in September 2006, Abe said that he would aim for a constitutional revision within five to six years. The central focus of attention is Article 9, in which Japan renounces the sovereign right to wage war. In May 2007, with relatively little fanfare, the Japanese Diet passed legislation to hold a national referendum to revise the constitution and amend Article 9.
