Imagine what would happen if the nations of the world spent as much on development as on building the machines of war. Imagine a world where every human being would live in freedom and dignity. Imagine a world in which we would shed the same tears when a child dies in Darfur or Vancouver. Imagine a world where we would settle our differences through diplomacy and dialogue and not through bombs or bullets. Imagine if the only nuclear weapons remaining were the relics in our museums. Imagine the legacy we could leave to our children.
Imagine that such a world is within our grasp.
