Hopefully this will pressure the PRC to pressure the DPRK. Says the Japan Times:
Japan needs to discuss whether it should go nuclear in response to North Korea’s declared nuclear test, the policy chief of the ruling Liberal Democratic Party said Sunday.
Shoichi Nakagawa, chairman of the LDP’s Policy Research Council, made the contentious comment on a TV Asahi talk show, saying the Constitution does not rule out the option of possessing nuclear arms.
Of course, the Prime Minister and everyone else came out saying the obligatory lines about sticking with the NPT and a rejection of nuclear weapons, but the more Japan talks, the more the PRC needs to be worried.
