President Kennedy has it within his power to end the Cold War. Two equally dramatic and effective paths are open to him to accomplish this purpose. He can end the Cold War by capitulating to Communist demands in Berlin, in Laos and in the disarmament dialogue, or he can end it by starting a hot war.

As long as Mr. Kennedy and the American people regard these alternatives as morally wrong and politically unwise, which I hope will be a long time, we will have to adjust to the perils and pitfalls of a notso- peaceful-coexistence. In this protracted conflict involving nuclear weapons (in being), unconventional warfare, diplomatic negotiations, trade, ideas and loyalties—in this novel twilight zone between war and peace—has the traditional doctrine of the just war any relevance? I believe it has. attempt to support the thesis that the traditional doctrine is relevant in principle to the nuclear-missile age, first by suggesting six necessary elements present in all moral-political decisions and then by sketching a brief outline for a “responsible” just war theory.
