"Real peace will not come from some magic formula that will suddenly and once and for all be "discovered," like the promised land or the holy grail. Real peace is a process — a continuing process for managing and containing conflict between competing nations, competing systems, and competing international ambitions. Peace is not an end to conflict but rather a means of living with conflict, and once established it requires constant attention or it will not survive."
