A senior Iranian military officer said renewed fighting with the United States is "likely" following Trump's dissatisfaction with an Iranian negotiating proposal.

There are no bodies yet, but the machinery of death is being oiled. In the space between a diplomatic rejection and a military order, there exists a vacuum where the Geneva Conventions are not merely ignored but rendered irrelevant by the sheer velocity of political posturing. The specific population at risk is not yet defined by casualty lists, but by geography and proximity: the civilians of Tehran, the sailors on US vessels in the Persian Gulf, and the millions whose livelihoods depend on the stability of the Strait of Hormuz. The rule that should protect them is the fundamental principle of distinction and the obligation to pursue peace through negotiation, as enshrined in the preamble of the Geneva Conventions and the UN Charter. Is it being followed? The rhetoric suggests otherwise.

When a senior military officer declares that renewed fighting is “likely” because a negotiating proposal was deemed inadequate, we are witnessing the collapse of the institutional buffer that separates statecraft from slaughter. I arrived at Solferino expecting a business meeting with Napoleon III. I found a field of forty thousand wounded men, dying in the sun, because the institutions of war had failed to account for the humanity of the combatant. Today, the failure is not in the field, but in the room. The failure is in the assumption that a disagreement over terms is a prelude to violence rather than a reason to deepen dialogue. The officer’s statement is not a prediction; it is a threat. And threats, when unanchored by the constraints of international law, become the first casualties of a conflict that has not yet begun.

We must count the suffering before it happens. This is not an exercise in pessimism; it is an exercise in institutional responsibility. If fighting resumes, the human cost will be immediate and disproportionate. The wounded will not be treated with the impartiality required by the First Geneva Convention of 1864, which I helped draft. They will be treated as political assets or liabilities. The hospitals will not be protected under the Second Geneva Convention of 1906. They will be targets, or worse, obstacles. The civilians will not be spared under the Fourth Geneva Convention of 1949. They will be collateral damage in a struggle for regional dominance. The rules exist. They are clear. They are signed by both the United States and Iran. But a signature on paper is not a shield against a missile. It is only a promise, and promises are worthless without the institutional will to enforce them.

The core wound of my life was not the sight of death, but the sight of preventable death. At Solferino, men died of thirst within sight of water because no one had organized the distribution. Today, men and women are at risk of dying because no one has organized the de-escalation. The diplomatic channel is not a formality; it is the primary humanitarian infrastructure of the modern world. When it breaks, the alternative is not justice; it is chaos. The officer’s assessment that war is “likely” reveals a dangerous inversion of logic. It suggests that the failure of negotiation is a cause for war, rather than a failure of the negotiators. In my time, we learned that war is not inevitable. It is a choice. And it is a choice that can be constrained by institutions.

The International Committee of the Red Cross and the broader humanitarian movement are built on the premise that even in war, there are limits. These limits are not moral aspirations; they are operational necessities. Without them, the wounded cannot be collected. The prisoners cannot be fed. The civilians cannot be protected. But these limits only work if the parties to the conflict agree to respect them. The current rhetoric from both sides suggests a willingness to discard these limits. The US dissatisfaction with the Iranian proposal is a political stance. The Iranian officer’s threat is a military stance. Neither is a humanitarian stance. And when politics and military strategy collide without the buffer of humanitarian law, the result is always the same: the vulnerable are crushed.

We must ask what institutional capacity exists to prevent this. The answer is insufficient. The diplomatic channels are strained. The humanitarian access agreements are fragile. The monitoring mechanisms for compliance with international humanitarian law are weak. We rely on the good faith of states that are actively preparing for war. This is not a system; it is a hope. And hope is not a strategy. At Solferino, I did not hope that the soldiers would stop fighting. I organized the women of the village to tend the wounded. I built the institution that would ensure that, in the future, the wounded would be cared for regardless of which side they fought for. Today, we need a similar institutional response. We need mechanisms that force de-escalation, not just mechanisms that respond to escalation.

The stakes are not just regional stability or oil markets. Those are the interests of states. The stakes are the lives of individuals. The specific suffering that will occur if this threat materializes is not abstract. It will be the mother in Tehran who loses her son to an airstrike. It will be the sailor in the Gulf who is captured and denied medical care. It will be the refugee who is displaced for the third time in a decade. These are not statistics. They are the human cost of a failure to uphold the rules of war before the war even begins.

The obligation is clear. The parties must return to the negotiating table, not as adversaries preparing for battle, but as signatories to the Geneva Conventions who have a duty to protect the civilian population. The rules are not optional. They are the minimum standard of civilization. When a military officer speaks of war as a likely outcome of diplomatic failure, he is not just threatening violence; he is threatening the entire framework of international humanitarian law. And if that framework collapses, we return to Solferino. We return to a world where the wounded are left to die in the sun, and no one is there to help them. That is not a future we can accept. It is a past we must prevent. The institution must be strengthened, not abandoned. The rules must be enforced, not ignored. The suffering must be counted, not ignored. This is the only way to ensure that the next time we look at a battlefield, we see not a slaughterhouse, but a place where humanity has been preserved, even in the midst of war.
