But with equal determination, the United States and all countries must find ways to control and reduce the horrifying danger that is posed by the world's enormous stockpiles of nuclear arms. This has been a concern of every American president since the moment we first saw what these weapons could do. Our leaders will require our understanding and our support as they grapple with this difficult but crucial challenge. There is no disagreement on the goals or the basic approach to controlling this enormous destructive force. The answer lies not just in the attitudes or actions of world leaders, but in the concern and demands of all of us as we continue our struggle to preserve the peace.
Nuclear weapons are an expression of one side of our human character.
But there is another side. The same rocket technology that delivers nuclear warheads has also taken us peacefully into space. We see no barriers of race or religion or country. Another major challenge, therefore, is to protect the quality of this world within which we live. The shadows that fail across the future are cast not only by the kinds of weapons we have built, but by the kind of world we will either nourish or neglect.
