SECTION 1 The Avoidance of War

79. Even though recent wars have wrought physical and moral havoc on our world, the devastation of battle still goes on day by day in some part of the world. Indeed, now that every kind of weapon produced by modern science is used in war, the fierce character of warfare threatens to lead the combatants to a savagery far surpassing that of the past. Furthermore, the complexity of the modern world and the intricacy of international relations allow guerrilla warfare to be drawn out by new methods of deceit and subversion. In many causes the use of terrorism is regarded as a new way to wage war.

Contemplating this melancholy state of humanity, the council wishes, above all things else, to recall the permanent binding force of universal natural law and its all-embracing principles. Man's conscience itself gives ever more emphatic voice to these principles. Therefore, actions which deliberately conflict with these same principles, as well as orders commanding such actions are criminal, and blind obedience cannot excuse those who yield to them. The most infamous among these are actions designed for the methodical extermination of an entire people, nation or ethnic minority. Such actions must be vehemently condemned as horrendous crimes. The courage of those who fearlessly and openly resist those who issue such commands merits supreme commendation.

On the subject of war, quite a large number of nations have subscribed to international agreements aimed at making military activity and its consequences less inhuman. Their stipulations deal with such matters as the treatment of wounded soldiers and prisoners. Agreements of this sort must be honoured. Indeed they should be improved upon so that the frightfulness of war can be better and more workably held in check. All men, especially government officials and experts in these matters, are bound to do everything they can to effect these improvements. Moreover, it seems right that laws make humane provisions for the case of those who for reasons of conscience refuse to bear arms, provided however, that they agree to serve the human community in some other way.

Certainly, war has not been rooted out of human affairs. As long as the danger of war remains and there is no competent and sufficiently powerful authority at the international level, governments cannot be denied the right to legitimate defense once every means of peaceful settlement has been exhausted. State authorities and others who share public responsibility have the duty to conduct such grave matters soberly and to protect the welfare of the people entrusted to their care. But it is one thing to undertake military action for the just defense of the people, and something else again to seek the subjugation of other nations. Nor, by the same token, does the mere fact that war has unhappily begun mean that all is fair between the warring parties.

Those too who devote themselves to the military service of their country should regard themselves as the agents of security and freedom of peoples. As long as they fulfil this role properly, they are making a genuine contribution to the establishment of peace.

80. The horror and perversity of war is immensely magnified by the addition of scientific weapons. For acts of war involving these weapons can inflict massive and indiscriminate destruction, thus going far beyond the bounds of legitimate defense. Indeed, if the kind of instruments which can now be found in the armories of the great nations were to be employed to their fullest, an almost total and altogether reciprocal slaughter of each side by the other would follow, not to mention the widespread devastation that would take place in the world and the deadly after effects that would be spawned by the use of weapons of this kind.

All these considerations compel us to undertake an evaluation of war with an entirely new attitude.[1] The men of our time must realize that they will have to give a sombre reckoning of their deeds of war for the course of the future will depend greatly on the decisions they make today.

With these truths in mind, this most holy synod makes its own the condemnations of total war already pronounced by recent popes,[2] and issues the following declaration.

Any act of war aimed indiscriminately at the destruction of entire cities of extensive areas along with their population is a crime against God and man himself. It merits unequivocal and unhesitating condemnation.

The unique hazard of modern warfare consists in this: it provides those who possess modern scientific weapons with a kind of occasion for perpetrating just such abominations; moreover, through a certain inexorable chain of events, it can catapult men into the most atrocious decisions. That such may never truly happen in the future, the bishops of the whole world gathered together, beg all men, especially government officials and military leaders, to give unremitting thought to their gigantic responsibility before God and the entire human race.

81. To be sure, scientific weapons are not amassed solely for use in war. Since the defensive strength of any nation is considered to be dependent upon its capacity for immediate retaliation, this accumulation of arms, which increases each year, likewise serves, in a way heretofore unknown, as deterrent to possible enemy attack. Many regard this procedure as the most effective way by which peace of a sort can be maintained between nations at the present time.

Whatever be the facts about this method of deterrence, men should be convinced that the arms race in which an already considerable number of countries are engaged is not a safe way to preserve a steady peace, nor is the so-called balance resulting from this race a sure and authentic peace. Rather than being eliminated thereby, the causes of war are in danger of being gradually aggravated. While extravagant sums are being spent for the furnishing of ever new weapons, an adequate remedy cannot be provided for the multiple miseries afflicting the whole modern world. Disagreements between nations are not really and radically healed; on the contrary, they spread the infection to other parts of the earth. New approaches based on reformed attitudes must be taken to remove this trap and to emancipate the world from its crushing anxiety through the restoration of genuine peace.

Therefore, we say it again: the arms race is an utterly treacherous trap for humanity, and one which ensnares the poor to an intolerable degree. It is much to be feared that if this race persists, it will eventually spawn all the lethal ruin whose path it is now making ready. Warned by the calamities which the human race has made possible, let us make use of the interlude granted us from above and for which we are thankful, to become more conscious of our own responsibility and to find means for resolving our disputes in a manner more worthy of man. Divine Providence urgently demands of us that we free ourselves from the age-old slavery of war. If we refuse to make this effort, we do not know where we will be led by the evil road we have set upon.

It is our clear duty, therefore, to strain every muscle in working for the time when all war can be completely outlawed by international consent. This goal undoubtedly requires the establishment of some universal public authority acknowledged as such by all and endowed with the power to safeguard on the behalf of all, security, regard for justice, and respect for rights. But before this hoped for authority can be set up, the highest existing international centres must devote themselves vigorously to the pursuit of better means for obtaining common security. Since peace must be born of mutual trust between nations and not be imposed on them through a fear of the available weapons, everyone must labour to put an end at last to the arms race, and to make a true beginning of disarmament, not unilaterally indeed, but proceeding at an equal pace according to agreement, and backed up by true and workable safeguards.[3]

82. In the meantime, efforts which have already been made and are still underway to eliminate the danger of war are not to be unde . On the contrary, support should be given to the good will of the very many leaders who work hard to do away with war, which they abominate. These men, although burdened by the extremely weighty preoccupations of their high office, are nonetheless moved by the very grave peacemaking task to which they are bound, even if they cannot ignore the complexity of matters as they stand. We should fervently ask God to give these men the strength to go forward perseveringly and to follow through courageously on this work of building peace with vigour. It is a work of supreme love for mankind. Today it certainly demands that they extend their thoughts and their spirit beyond the confines of their own nation, that they put aside national selfishness and ambition to dominate other nations, and that they nourish a profound reverence for the whole of humanity, which is already making its way so laboriously toward greater unity.

The problems of peace and of disarmament have already been the subject of extensive, strenuous and constant examination. Together with international meetings dealing with these problems, such studies should be regarded as the first steps toward solving these serious questions, and should be promoted with even greater urgency by way of yielding concrete results in the future.

Nevertheless, men should take heed not to entrust themselves only to the efforts of some, while not caring about their own attitudes. For government officials who must at one and the same time guarantee the good of their own people and promote the universal good are very greatly dependent on public opinion and feeling. It does them no good to work for peace as long as feelings of hostility, contempt and distrust, as well as racial hatred and unbending ideologies, continue to divide men and place them in opposing camps. Consequently there is above all a pressing need for a renewed education of attitudes and for new inspiration in public opinion. Those who are dedicated to the work of education, particularly of the young, or who mold public opinion, should consider it their most weighty task to instruct all in fresh sentiments of peace. Indeed, we all need a change of heart as we regard the entire world and those tasks which we can perform in unison for the betterment of our race.

But we should not let false hope deceive us. For unless enmities and hatred are put away and firm, honest agreements concerning world peace are reached in the future, humanity, which already is in the middle of a grave crisis, even though it is endowed with remarkable knowledge, will perhaps be brought to that dismal hour in which it will experience no peace other than the dreadful peace of death. But, while we say this, the Church of Christ, present in the midst of the anxiety of this age, does not cease to hope most firmly. She intends to propose to our age over and over again, in season and out of season, this apostolic message: "Behold, now is the acceptable time for a change of heart; behold! now is the day of salvation."[4]
