The bright laughter of children is the true measure of a society's health. Ten years ago, I was in San Jose, Costa Rica, for the opening of an exhibition on the reality and threat of nuclear weapons. Even as participants began a dignified rendition of the national anthem, through the wall that separated the venue from the Children's Museum next door came the sound of free and raucous voices -- elementary school pupils waiting for the exhibition to open. As the ceremony proceeded, the noise generated by the children at times came close to drowning out the speeches of the invited guests.
The ceremony participants exchanged smiles. It seemed that the cheerful and vibrant voices of the children were the symbol and embodiment of peace. Their voices conveyed a sense of hope capable of countering even the threat posed by nuclear weapons.
As adults, it is our responsibility to ensure that these pure voices resonate loudly throughout society. And yet, in Japan in recent years, hardly a day passes without news of tragic and disturbing incidents involving children. It is painful in the extreme to learn of children and young people falling victim to or becoming otherwise entangled in violent crime.
