When we treat peace as a distant ideal, we cease to be scandalized when it is denied, or even when war is waged in its name. We seem to lack those “right ideas,” the well-considered words and the ability to say that peace is near. When peace is not a reality that is lived, cultivated and protected, then aggression spreads into domestic and public life. In the relations between citizens and rulers, it could even be considered a fault not to be sufficiently prepared for war, not to react to attacks, and not to return violence for violence. Far beyond the principle of legitimate defense, such confrontational logic now dominates global politics, deepening instability and unpredictability day by day. It is no coincidence that repeated calls to increase military spending, and the choices that follow, are presented by many government leaders as a justified response to external threats. The idea of the deterrent power of military might, especially nuclear deterrence, is based on the irrationality of relations between nations, built not on law, justice and trust, but on fear and domination by force. “Consequently,” as Saint John XXIII had already written in his day, “people are living in the grip of constant fear. They are afraid that at any moment the impending storm may break upon them with horrific violence. And they have good reasons for their fear, for there is certainly no lack of such weapons. While it is difficult to believe that anyone would dare to assume responsibility for initiating the appalling slaughter and destruction that war would bring in its wake, there is no denying that the conflagration could be started by some chance and unforeseen circumstance.”

… And yet, “those who truly love peace also love the enemies of peace.” Saint Augustine thus advised not to burn bridges or persist in reproach, but to prefer listening and, where possible, engaging in discussions with others… Reiterating the appeal of the Council Fathers, and considering dialogue to be the most effective approach at every level, we must acknowledge that further technological advances and the military implementation of artificial intelligence have worsened the tragedy of armed conflict. There is even a growing tendency among political and military leaders to shirk responsibility, as decisions about life and death are increasingly “delegated” to machines. This marks an unprecedented and destructive betrayal of the legal and philosophical principles of humanism that underlie and safeguard every civilization. It is necessary to denounce the enormous concentrations of private economic and financial interests that are driving States in this direction; yet that alone would not be enough, unless we also awakened conscience and critical thought… that means joining forces to contribute to a disarming peace, a peace born of openness and evangelical humility.

A disarming peace
Goodness is disarming. Perhaps this is why God became a child. The mystery of the Incarnation, which reaches its deepest descent even to the realm of the dead, begins in the womb of a young mother and is revealed in the manger in Bethlehem. “Peace on earth,” sing the angels, announcing the presence of a defenseless God, in whom humanity can discover itself as loved only by caring for him (cf. Lk 2:13-14). Nothing has the power to change us as much as a child. Perhaps it is precisely the thought of our children and of others who are equally fragile, that cuts to the heart (cf. Acts 2:37)… John XXIII was the first pope to advocate “integral disarmament” … In Pacem in Terris, he wrote: “Everyone must realize that, unless this process of disarmament be thoroughgoing and complete, and reach people’s very souls, it is impossible to stop the arms race, or to reduce armaments, or — and this is the main thing — ultimately to abolish them entirely. Everyone must sincerely co-operate in the effort to banish fear and the anxious expectation of war from our minds. But this requires that the fundamental principles upon which peace is based in today’s world be replaced by an altogether different one, namely, the realization that true and lasting peace among nations cannot consist in the possession of an equal supply of armaments but only in mutual trust. And we are confident that this can be achieved, for it is a thing which not only is dictated by common sense, but is in itself most desirable and most fruitful.”
