It has taken mankind more than 20 centuries to achieve the fundamental insight embodied in the United Nations Charter that aggressive use of force is impermissible in international affairs and that every nation has a right of individual and collective defense against such aggressive use of force. This dual insight-which was the single most important advance in the history of conflict management-is the principal foundation of modern world order.
