"We must abandon the unworkable notion that it is morally reprehensible for some countries to pursue weapons of mass destruction yet morally acceptable for others to rely on them for security — and indeed to continue to refine their capacities and postulate plans for their use. Similarly, we must abandon the traditional approach of defining security in terms of boundaries — city walls, border patrols, racial and religious groupings. The global community has become irreversibly interdependent, with the constant movement of people, ideas, goods and resources. In such a world, we must combat terrorism with an infectious security culture that crosses borders — an inclusive approach to security based on solidarity and the value of human life. In such a world, weapons of mass destruction have no place."
