Though it seemed to be an opening bid in a negotiation that, mercifully, ended in a provisional ceasefire, President Trump’s Truth Social post on Tuesday morning was a moment of bellicose escalation far exceeding the boundaries of moral combat.
“A whole civilization will die tonight, never to be brought back again,” the president wrote, referencing the Iranian people. He added, almost as an afterthought, that he didn’t want that to happen—but that it “probably will.” What followed was a curious mixture of fatalism and optimism: Perhaps something “revolutionarily wonderful” might still occur, “WHO KNOWS?” Such a statement violates principles of the Geneva Convention that protect civilian populations.
I have spent years teaching the just war tradition. Nothing in that tradition provides cover for this kind of language. The deliberate targeting of a civilian population, or even the credible threat of it as a negotiating instrument, is not a gray area in classical moral reasoning. It is a violation of the ius in bello principles of discrimination and proportionality that have governed Western moral thought.
Rhetorical precision matters in statecraft. I am not convinced this statement reflects a sincere military intention. This reads far more like strategic bluster—the kind of extreme threat designed to rattle an adversary and extract concessions before a deadline. The president has employed this tactic before. It is a form of coercive diplomacy, and coercive diplomacy is not inherently illegitimate. Nations have always used the threat of force to avoid resorting to it.
It may be the type of language that the Iranian regime, accustomed as it is to wielding raw power, takes seriously. But America should not resort to the types of rhetoric used by theocracies. The whole charade lacks proportion and restraint.
Here is what bluster-as-strategy does not escape: the moral evaluation of the speech act itself.
Words from the office of the president of the United States are not mere noise. They carry sovereign weight. When a sitting president says that an entire civilization will probably die, he has done something morally serious regardless of whether he intends to follow through. He has normalized genocidal rhetoric as a negotiating tool. He has told 90 million Iranian civilians, who did not choose their government and indeed often languish underneath it, that their extinction is an acceptable instrument of American foreign policy. He has communicated to the international order that the United States calculates civilian populations as bargaining chips.
The just war tradition does not merely regulate the conduct of war. It governs the decision to threaten war, and it demands that such threats be proportionate, discriminate, and oriented toward genuine peace. Threatening civilizational annihilation to force open a shipping lane fails that standard on every count.
This is a moral point, not a partisan one. And I would make it regardless of who occupied the Oval Office.
Sen. Chris Murphy of Connecticut said something worth examining in the aftermath of the president’s post. He took to social media in response to the president’s remarks and wrote: “In an age of creeping relativism, a universal moral law still exists. Threatening to end an entire civilization of 90 million people in order to bend a nation’s conduct to your will is grossly morally wrong. It is evil. And we should say this loudly.”
Sen. Murphy is right. A universal moral law does exist. It is not a partisan invention nor only a mere religious imposition. It is inscribed in the structure of creation, accessible to reason, and confirmed by divine revelation. But I want to press Sen. Murphy—and the Democratic Party he represents—on a point that he has left conspicuously unaddressed. The moral law that rightly prohibits threatening to end the lives of 90 million Iranians is the same moral law that prohibits the deliberate killing of more than 60 million unborn American children since 1973. It is the same moral law that grounds the inherent dignity of every human being—not because they are born, not because they are citizens, but because they bear the image of God and possess a nature ordered toward life and flourishing, whether in the womb or outside of it.
Sen. Murphy has never, to my knowledge, invoked a “universal moral law” to condemn abortion. His party has not merely tolerated the procedure; it has enshrined it as a fundamental right, resisted every legislative limit upon it, and treated opposition to it as a form of religious extremism to be excluded from public life.
I do not raise this to deflect from the president’s reckless rhetoric, which deserves the condemnation it has received. I raise it because moral reasoning only carries authority when it is applied consistently. The senator cannot summon a universal moral law to condemn the president’s threat against Iranian lives and then return to Washington to vote against protections for American unborn lives. That is not moral reasoning; it is partiality draped in moral language.
Real moral authority requires consistency. It requires the willingness to follow the logic of the moral law wherever it leads, even when it indicts your own coalition or your own party’s platform.
To President Trump I say: The just war tradition is not optional for a statesman. Threats of civilizational destruction, even as bluster, degrade the moral seriousness that legitimate statecraft requires. To Sen. Murphy: You are correct that a universal moral law exists. I welcome you to that tradition. Do us all a favor and follow it consistently.
Speech acts only retain authority if they are grounded in moral seriousness. Left and right alike need to recover this.
