Perhaps never before has the reality of a just and lasting peace among nations been so ardently desired and so urgently sought. This desire is inspired not so much by a hunger for the benfits of peace as it is by a horror of the consequences if peace is not achieved.
1 The elements of the doctrine in its final formulation may be summarized as follows: 1) the war must be declared by the legitimate public authority; 2) a real injury must have been suffered; 3) the damage, likely to be incurred by the war, may not be disproportionate to the injury suffered; 4) there mustbe reasonable hope of success; 5) all possible means of peaceful settlement must have failed; 6) those prosecuting the war must have the right intention; and 7) only legitimate and moral means may be employed in prosecuting the war.Google Scholar Cf., McKenna, Joseph C., S.J., “Ethics and War: A Catholic View,” American Political Science Review, LIV (09, 1960), 647–58;CrossRefGoogle Scholar and Eppstein, John, The Catholic Tradition of the Law of Nations (Washington, 1935).Google Scholar

6 Though our immediate concern here is with the position of the civilian noncombatant in the extreme situation of nuclear war, the continuing conflict in Viet Nam aptly demonstrates the problem of distinction and protection of the civilian population. In this case only conventional weapons are being employed, though of course the nature of guerrilla conflict itself adds a further complicating dimension.

It should be noted that Augustine's concern is with the conditions under which, in modern terminology, “aggressive” war might be justified; “defensive” war in se was nearly always considered just.

18 Though it is often blurred, there is nevertheless an important distinction between the Peace of God, which intended to immunize persons and things from attack, and the Truce of God, which sought to limit war's duration by restricting legitimate combat to certain prescribed times. The Peace antedated the Truce by a century. Eventually the distinction was lost and both institutions came to be known simply as Treuga Dei (or, as in Germany, Gottesfrieden).
19 The available commentaries in English, French, and German on the Peace and Truce of God are of limited value.

33 It is true that Secretary McNamara's strategic planning in the past few years has come to stress “limited war capability” and “graduated response,” both representing a praiseworthy shift from the Dulles policy of “massive retaliation.” However, these policies still fail to come to grips with the possible ultimate nuclear situation in which population complexes are tacitly held hostage, largely because they continue to operate within the traditional combatant-noncombatant classification.
34 This proposed alternative raises many practical problems related to definition of new categories of innocence, agreement among policy-makers on these definitions, and development of military weapons-systems designed to operate within the new limits. These problems, however, are not insurmountable. The net gain would, at the very least, be the establishment of new ethical guidelines for political and military action, and an elimination of the present “either” - “or”impasse.
