Nuclear Japan?

Following North Korea's nuclear experiment,one of the LDP member gave controversial comment that we Japan should start discussing about the justices of holding nuclear weapon or not,which as a matter of course brought about much criticism regardless of inside or outside of Japan.Major reaction from other countries were that Japan seems finally started trying to lift non-nuclear policy.Though I also think it's extravagant idea to hold such weapon,I have a little different opinion about his comment.In this significant timing of this current issue,the government should give its general opinion to those who may start to think about the possibility of holding a weapon as a minimum defense,not as starting discussion but just to ease the anxiety by the citizen.To tell the truth,my mother also have positive idea of holding nuclear weapon.It was a pity that a LDP member in question didn't make a proper excuse.
