Just War: Common Complaints



        Through 25 years of writing and thinking about war, I keep running into the same mistakes. People either treat war as always immoral, or they toss the term ‘war crime’ around as a catchall. This post explains the common misconceptions about just war, show how medieval and modern theorists actually enlarged moral protections for civilians, and argue that force, in narrowly defined circumstances, can be a needed last resort to prevent slaughter.

War is clearly wrong

        Who watches the destruction and heart ache on the evening news and believes that God wants that? Yet just as quickly one might remember the abject slaughter of the helpless and we must ask, what happens when the absence of force results in even greater evil than war? Yazidi sex slaves, kidnapped Ukrainian children, cartels sex trafficking immigrants, to the slaughtered innocents on October 7th, and those still tortured and starved by Hamas in captivity all show us the evil that men do. If the Good Samaritan happened upon the beaten traveler in the middle of the attack and not after, he would lift the sword to protect his neighbor. Like the Good Samaritan, we should love our brothers enough to raise the sword in their defense. The need for force and God given desire to “deliver the poor and needy” (Psalms 82:4) then becomes a good thing, because it stops or prevents abject slaughter.

        While no one wants war, because you need to stop a slaughter, many people recognize the tragic need for war on an intuitive level.

Anything I don’t like is a war crime

        People believe, like Paul Ramsey described, that civilians are roped off from harm like the ladies at a medieval tournament.[1] So, any time civilians are killed, churches struck, or some other tragedy occurs it must be a war crime.

        But real war crimes require actual laws of war. Augustine, the first just war theorist, talked about right intention including a desire to restore a just and peaceful order.[2] The medieval thinker, Gratian in the Decretum named protected groups like pilgrims, clerics, women, and unarmed peasants.[3] Salamanca school scholar Francisco De Vitoria wrote that indigenous people can’t be slaughtered simply for not being Christian. He said: “War is no argument for the truth of the Christian faith.”[4]

        Civilian deaths are tragic, but not every tragedy is a war crime. Intent, environment, and proximity to combatants all matter. Terrorists like Hamas exploit this by hiding behind civilians. The laws of war are clear: using civilians as shields is a violation; unintended strikes, even on churches or those that kill children, are not. That tragedy remains awful, but Hamas chose it when they launched terror attacks and then hid beneath hospitals, schools, and churches.

        Some use every tragedy to reject force altogether, but that simply guarantees victims will be slaughtered. Pacifism often implies it is better to let atrocities continue than to risk civilian harm. Outrage over an accidental strike can overshadow the deeper outrage that started the war but it shouldn't. 

Moroni was militaristic and not a source of peace

        Moroni has been cited for militaristic means. During my mission in Texas, I visited compounds with pictures of Moroni on the wall. But closely reading the text we see that Moroni repeatedly brought peace to such a degree that the Lamanites rebelled against their king rather than take up arms.

        In the face of an implacably murderous ideology, Moroni showed that battlefield defeat discredits that radical ideology that led to war and produced peace. He was such an expert peacemaker that he converted committed fanatics during battle numerous times. Based on those battlefield covenants he arguably converted more people than the missionary preaching and the self-sacrifice of the Anti-Nephi Lehis. As recorded in Alma 47:2 and Helaman 4:3, those that didn’t make that covenant were still inclined towards peace years later. His actions didn’t result from or instigate a cycle of violence but led to long eras of peace and more peace, defiance of cultural stereotypes, and generosity than produced or showed by Ammon and his brethren. The righteous example of Moroni suggests a path to peace that comes from decisive victory we must recognize and apply, regardless of how uncomfortable his example might make some people.

Anyone I don't like is a simp for war 

        This is usually wrapped up in insults like I’m an insane, warmongering anti-Christ that hasn’t met a war criminal I won’t simp for. These insults contain multiple ironies.

        First, I’m old enough and have been studying history long enough I remember wanting actual war criminals like Slobodan Milosevic and Uday and Qusay Hussein locked up and executed.

        Second, it’s always the least educated people I met, those with limited education and no publications, who insult my intelligence, education, and publications.

        Third, Augustine warned “the passion for inflicting harm, the cruel thirst for vengeance, an unpacific and relentless spirit” leads to war.[5] But I see this war like spirit every time I explain basic ideas about just war, defend Israel, and simply disagree with a pacifist. I’m the “war monger,” but they show more passion for war by their cruel thirst for insulting me.

        Aside from all that irony, I’m pro war to the extent I’m anti genocide and mass rape. When Putin launches the most nakedly aggressive war of my lifetime (and I’m old enough to have lived through the Soviet Union), it’s easy to stand against it. When I see the worst holocaust since the Holocaust, I must stand against it. Just war grounds me in the conviction that I am aligned with God’s justice, and equips me to answer objections without fear. (Though, I'll confess, not without annoyance.) 

Just war only justifies war

       Just war has always critiqued governments as much as it has supported force. I already mentioned the concern of the just war theorists towards civilians but there is more. Vitoria criticized Spanish policy towards colonials he and his fellow scholars led to reforms.  This was during the age of discovery and conquistadors. So, what many people consider the worst abuses of the West were being critiqued and changed by just war theorists.

        Decretalists in the Middle Ages and those like Gregory IX increasingly moved society from settling disputes by combat to settling them by lawsuit and the rule of law.[6] They did this by aiming just war principles at wars of aggrandizement. For example, they argued that losses in wars of dubious morality, such as the armor and horses of a lord’s knights, could justify a legal claim requiring the lord to provide reimbursement. Since arms, armor, and horses were costly to replace, this made war far less profitable and thus discouraged campaigns unless there was a strong justification, such as repelling a rival king’s invasion, defending against robbers, or fulfilling duty to the crown. Again, during what many people consider a darkened age of unrestrained violence just war theorists were using a careful reading of religion and the law to limit the bloodshed.

        Far from sanctioning violence, just war thinkers used theology and law to restrain war and promote peace. Their concern for civilians laid the foundation of today’s laws of war. The irony is that medieval scholars had a more nuanced and devout grasp of thorny issues regarding war and peace than many modern critics who dismiss them.

Mormons have the restored truth, why bother with medieval Catholics?

       If you’ve read this far, you already know medieval Catholics were serious thinkers wrestling with the very questions we still face. Just war theorists like Aquinas, Vitoria, and Grotius have addressed revolution, civilian casualties, war crimes, and complex questions of law centuries before us. Their work still sharpens debates today. Duane Boyce’s argument about preemptive war, among others, could have been much sharper had he relied on the criteria of Hugo Grotius. Patrick Mason and David Pulsipher could better understand scriptures like Moroni 7:26 by using just war principles. Mark Henshaw could find additional material about just peace from those medieval Catholics.

        Mormonism is young. We don’t yet have a systematic theology, let alone our Augustine. Much of our debate unintentionally echoes older Christian conversations, only with different proof texts and less rigor. To dismiss their wisdom while boasting about “restored truth” is more chauvinism than confidence.

        As Brigham Young counselled: 

Whether a truth be found with professed infidels… it is the business of the Elders of this Church to gather up all the truths in the world pertaining to life and salvation…and bring it to Zion.[7]

This war seems politically motivated and grey

        I call this the bio lab defense.[8] When Russia invaded Ukraine, everyone suddenly became an expert on history, NATO, and bioweapons labs, muddying the waters until it felt acceptable to doubt the justice of the war.

        The same thing happened with Israel after the October 7th attack, the worst slaughter of Jews since WWII. People brought up radical Israeli terrorists from the ’90s or questioned the Jewishness of the victims.

        Many other good people, who are generally inclined to help, are left confused and like Joseph Smith, they hear a war of words and tumult of opinions and don’t know which side is correct. But just war is no simpler than this: do you feel genuine sadness and a desire to stop the injustice? That is love and compassion. Then ask: do you love your neighbor enough to act, or do you follow distractions—NATO, labs, space lasers—that let you ignore that call? 

       A country’s history may be imperfect, its leaders questionable, and the issue complex, yet there can still be an unmistakable duty to stop a slaughter. Jesus chose a despised ethnic rival and bitter enemy, a Samaritan, to show the kind of love we should have for our neighbor.

Conclusion 

        The lessons of just war theory are not just historical curiosities or sophistry. They are tools for moral clarity in our own time. Study the thinkers who wrestled with the limits of force, the protection of civilians, and the pursuit of peace. Reflect on scripture, history, and contemporary events, and ask yourself whether your compassion compels you to act. Challenge your assumptions, weigh difficult moral questions, and let a spirit of just peace guide your words, your judgments, and your actions. True moral courage comes not from avoiding conflict, but from confronting injustice thoughtfully, decisively, and ethically.
