Trump threatens strikes on Iranian infrastructure same day Pope Leo appeals for peace
President Donald Trump threatened to strike Iranian energy and transportation infrastructure if the Strait of Hormuz is not reopened. The threat was issued via social media on the same day Pope Leo XIV delivered an Easter appeal for global peace. Trump's proposed targeting of civilian infrastructure has raised concerns regarding international law and potential war crimes. The escalation follows ongoing combat operations between the U.S., Israel, and Iran that have significantly disrupted regional supply chains.

Evaluate Catholic teaching on war versus peace in the context of targeting civilian infrastructure
Catholic teaching does not treat war and peace as morally equal “options.” Peace is a positive moral good rooted in justice and charity, while war—though sometimes thinkable under conditions of legitimate defense—is morally burdened by its evils and by the duty to protect the innocent. In particular, in the context of attacking civilian infrastructure, the Church strongly emphasizes that operations must respect international humanitarian law and must not involve civilians or deliberately devastate essential civilian goods (such as hospitals, energy systems, and homes).
The Church teaches that peace is “the tranquillity of order” and is not simply the quieting of weapons. Peace requires safeguarding the goods of persons, free communication, respect for the dignity of persons and peoples, and fraternity—so it is fundamentally bound up with justice and charity.
This matters morally because it sets the Church’s perspective on conflict: even when force is claimed as necessary, the moral goal is not “victory at any cost,” but the protection and restoration of human dignity. The Compendium summarizes this in a way that directly frames the “war vs. peace” question: peace is justice’s work and charity’s effect, not something force can generate by itself.
Accordingly, the Church insists that war’s evils are real and that everyone should work—through prayer and action—for deliverance from “the ancient bondage of war,” because war brings evils and injustices.
Catholic moral teaching allows that legitimate defense can be a right and even a grave duty for those responsible for others’ safety. The Catechism explains legitimate defense using the moral idea of double effect: the intended purpose is protection of one’s own life, while the harm to an aggressor is not the intended end. In addition, public authority has the right/duty to repel armed aggressors to preserve the common good.
But legitimate defense does not erase moral limits. The Catechism is explicit that:
Similarly, the Compendium links the “right to use force” to a duty to protect innocent victims who cannot defend themselves. It warns that in modern conflicts civilians are often wrongly “hit” and sometimes even made targets; it calls forced transfers and “ethnic cleansing” “always unacceptable,” and insists humanitarian aid must reach civilians and never be used to influence them.
The US bishops’ teaching on peace applies this more directly to the moral evaluation of violence: Catholics must avoid war and promote peace, recognizing that war’s harms to human life are severe; nevertheless, the tradition also acknowledges the legitimacy of just-war teaching when defending the innocent against grave evil—while still requiring effective peaceful prevention, peaceful dispute resolution, and ethical restraint in means used.
When the question is specifically civilian infrastructure, the Church’s recent magisterial statements are unusually concrete.
Pope Leo XIV, addressing the diplomatic corps, explicitly states that destroying “hospitals, energy infrastructure, homes and places essential to daily life” is a “serious violation of international humanitarian law,” and he reiterates condemnation of “any form of involvement of civilians in military operations.”
That is a major moral point: even if a military actor claims strategic objectives, the Church treats the deliberate destruction of essential civilian systems as crossing a moral boundary grounded in international humanitarian law and the sanctity of life.
Pope Francis similarly notes that modern wars may no longer respect the distinction between military and civil targets, and he cites events such as Ukraine and Gaza as evidence. He adds that grave violations of international humanitarian law are war crimes, and it is not enough merely to point them out—one must also prevent them.
Francis also adds a key ethical corrective: even when exercising the right of legitimate defense, there must be “a proportionate use of force”; and civilian victims are not “collateral damage,” but real human beings with names and surnames.
So, in Catholic moral reasoning, attacks that predictably and massively harm civilian life or that treat civilians as disposable are not morally neutral “side effects”—they become an indicator that the attack fails the moral logic of humane, ordered defense.
The Holy See’s interventions in debates on protecting civilians in armed conflict emphasize that modern urban conflicts devastate critical civilian infrastructure—hospitals, sanitation systems, schools, places of worship—and that such damage produces lasting harms (disease outbreaks, displacement, loss of dignity and hope). The Church notes that distinguishing combatants from non-combatants in densely populated areas can be extremely difficult, which in turn challenges whether certain uses of force are lawful in those settings.
In another address, the Holy See commends efforts to protect civilian infrastructure critical to essential services and urges full implementation of such protections, including protecting places of worship as analogous to schools or hospitals because of their social and humanitarian role in society.
Putting these themes together, Catholic teaching implies the following moral evaluation:
Catholic teaching does not deny that authorities may have duties to defend against real aggression; however, the moral framework consistently emphasizes that this defense is measured by respect for humanitarian law and the dignity of civilians, including by ensuring proportionate force and preventing grave violations. In the specific case of civilian infrastructure destruction—especially hospitals and essential civilian services—the Church’s explicit statements indicate that such conduct is not merely regrettable; it is morally and legally serious.
Catholic teaching presents peace as a positive moral good grounded in justice and charity, while war is morally burdened by its inherent evils and—when it occurs—must remain ordered to protecting the innocent under the law of nations. In light of recent magisterial statements, the targeting (or deliberate destruction) of civilian infrastructure—notably hospitals, energy systems, homes, and other essentials—is treated as a serious violation of international humanitarian law and a grave threat to human dignity, requiring condemnation, prevention of violations, and urgent pursuit of ceasefire and dialogue.
