A movie scene has revived to my mind again and again recently. In the Brazilian movie "City of God", a kid gang pointed a gun on an adult and threatened him. The adult laughed away the threat of the kid, putting an expression that such a kid could no way shoot him. But he got shot without any difficulty.
How come on earth he thought not to get shot? He may have believed the value of growth at the bottom of heart in spite that he had lived in an outlaw community. "I have lived much longer and experienced many things. So I am rich in humanity to the extent that cannot be compared with such a kid."
Actually the action of shooting a gun is no more than pulling a trigger. An undergrown kid rather can do it indiscriminately.
The most destructive weapon is nuclear weapon. Although all wars bring about vulgarization of humanity, wars fought by conventional weapons still need leadership to subordinates as well as conviction to the worldwide people. On the other hand, nuclear weapon is able to change the situation with just a fingertip.
Therefore, those who aim at changing a situation with nuclear weapons can abandon efforts for his or her own growth. The true terror of nuclear weapons exists in here. And the true nature of devilish charm with nuclear weapons also exists in the point that they allow us to mentally regress to undergrown state.
15000 years have passed since mankind began agriculture. We have undergone at least two crises of nuclear war so far, although only 80 years have passed since nuclear weapon came into existence. Simply calculating, similar crises are expected 375 times in future 15000 years. Is it possible for us to overcome all of them? If we suppose human civilization is so great that nobody can easily destruct it, we are making too slight of the strong affinity between nuclear weapon and mental regress.
