The Iranians have declared victory.

Yes—and it is rather striking rhetoric. Iran's President Masoud Pezeshkian said on Friday that “the entire world” had accepted Iran's victory and that the war should now end.

But I think the interesting question is what “victory” means here. Iran plainly did not defeat the United States militarily. Its infrastructure and economy have suffered enormously, and the war has not produced the Iranian objectives one would normally associate with a military victory.

On the other hand, Iran can make a respectable case for a political or strategic victory: the regime survived, the United States did not achieve regime change, Iran's nuclear program was not demonstrably eliminated, and—most importantly—the Americans have not been able to force Tehran to reopen the Strait of Hormuz on American terms. Reuters notes that the U.S. has still not achieved several of its original objectives.

And there is a delicious irony in the situation: Trump has been preparing his own “victory” narrative, apparently hoping that reopening Hormuz would give him a basis for declaring the war won.

So we have the classic modern-war ending: both sides declaring victory because neither has obtained what it wanted badly enough to call the other side the winner.

Indeed, Pezeshkian's formulation—we should end the war now, while we are powerful and our dignity is intact—is almost an explicit description of a negotiated stalemate being packaged as victory.

And I suspect that's what makes the declaration interesting rather than merely absurd.

The respective victories of both Iran and the States can be described as Pyrrhic. 

Yes. “Pyrrhic” fits remarkably well precisely because victory is being defined negatively.

Iran can say: We survived, preserved the regime, and denied the Americans their maximal objectives. The United States can say: We inflicted enormous damage, imposed costs, and denied Iran what it wanted. Neither side can comfortably say, We achieved our objectives at an acceptable price.

And a Pyrrhic victory has that peculiar feature: the winner's victory itself contains the evidence of how badly the contest went. The destruction, disruption, expenditure, and political consequences remain after the banners come down.

There is also a nice distinction between military victory and strategic success here. A side can lose militarily yet achieve enough strategically to call the result a victory; conversely, a side can win militarily and discover that the political result isn't worth the cost.

So “both sides won” isn't necessarily nonsense. It can mean both sides salvaged something from a contest in which neither got what it really wanted. That is almost the textbook soil in which Pyrrhic victories grow.

Yes. Morally, I think there is a very important distinction between killing a leader as a military act and using the threat or act of killing a leader as a diplomatic instrument.

My instinct is that the latter is morally troubling even when the former might sometimes be justified. A government can properly regard an enemy commander who is directing an ongoing war as a legitimate military target; international humanitarian law makes essentially that distinction. Political officials, merely by virtue of being political officials, are not automatically lawful targets.

But “we'll kill your leadership unless you do what we demand” is something rather different. It turns assassination into a negotiating mechanism. The moral problem is not simply that a person dies; it is that the state is saying, in effect, your government's continued existence depends upon our willingness to kill particular people. That begins to resemble coercion by threat of murder rather than diplomacy.

There is also a nasty practical paradox. Removing a dictator does not remove the political system that produced him. It may produce a successor who is harder to deal with, a martyr, a factional struggle, or simply another leader who concludes that negotiating with the assassin is suicidal. In other words, it can make compromise less attractive to the other side. And once states normalize the principle that political leadership is fair game, they have created a precedent that can be used against their own leaders.

That is why I would distinguish three propositions:

“This leader is a military commander and is participating directly in the war.” Potentially legitimate.

“This leader is responsible for terrible things, therefore he may be killed.” Morally much more dubious.

“We will kill your leaders to make your government negotiate with us.” I think that is especially objectionable. It substitutes coercive elimination for diplomacy and tends toward a world in which heads of government become hostages to international politics.

And there is an especially interesting wrinkle in the present Iran situation: if the stated objective is diplomacy, killing the people with whom you must ultimately negotiate is almost self-defeating. You are simultaneously destroying the interlocutors and telling the surviving government that accommodation may get its negotiators killed.

The legal question is somewhat separate: under the UN Charter, the use of force against another state's political independence is heavily constrained, while once an armed conflict exists, the law of war governs who may be attacked.

So morally, I would put it this way: a leader can become a legitimate military target because of what he is doing in a war; he does not become morally killable merely because killing him is thought to be a useful way of getting his country to behave.

And I suspect that distinction is close to what you are getting at by calling it a diplomatic tactic.

The Afghanistan war had a lot of that sort of thing: kill the leaders.  Over time those who replace the leaders tend to become both less competent and less committed, until one gets a group one can deal with.

Yes—and Afghanistan is a useful example because your hypothesis has some empirical support, though I would qualify the last part.

There is evidence that killing Taliban leaders could degrade the organization's professionalism and operational effectiveness. One study of four Taliban leadership killings in Afghanistan found reduced professionalism, lower success rates, changes in target selection, and weakened morale.

But the succession effect isn't reliably “each replacement is worse.” It depends heavily on the organization's structure. Research on nearly a thousand cases finds that decapitation is much less likely to destroy organizations that are bureaucratic, have substantial communal support, or are driven by religious or separatist ideology—the sort of characteristics the Taliban possessed.

And there is an intriguing possibility very close to what you're describing: successive removals can alter the composition of the leadership and its incentives, potentially producing people who are less capable of sustaining the old organization or more willing to bargain. Recent work specifically argues that leadership removal can affect the bargaining process, not merely battlefield effectiveness.

So I might phrase your idea as:

    You don't necessarily decapitate an organization until it collapses; you decapitate it until the people who emerge from the succession process are people you can do business with.

That is a rather different conception of “decapitation” from simply trying to win by assassination. It makes the killing of leaders a mechanism for altering the political constituency on the other side.

And there's the moral wrinkle we were discussing. Once that is the objective, the justification becomes less “this man is a combatant” and more “we are deliberately killing political actors to manufacture a more tractable opponent.” That strikes me as considerably harder to defend morally, even if it might occasionally be effective.

The regime in Afghanistan now is merely unpleasant, not horrible, and it did seem to work quite well in Venezuela, where of the arrest could be justified on criminal grounds.

I think there is something to your comparison, though I would soften the Afghanistan description. For much of the Afghan population, particularly men living ordinary lives, the Taliban regime may indeed seem more like a grim, restrictive government than the apocalyptic regime it was depicted as during its worst years of insurgency. But for women and girls it is still extraordinarily repressive: the UN describes systematic exclusion from education, employment, public life and legal equality, with new restrictions added in 2026.

Venezuela is the cleaner example of the phenomenon you're describing. On January 3, 2026, U.S. forces captured Nicolás Maduro alive and transported him to the United States for prosecution on federal criminal charges. The U.S. government explicitly presented it as a law-enforcement operation supported by military force, rather than as an assassination. A federal court had issued arrest warrants based on grand-jury indictments.

And, interestingly, it seems to have worked better than simply killing him might have. Maduro disappeared from the political equation, but the Venezuelan state did not collapse. Delcy Rodríguez became interim president, while much of the existing political and military apparatus remained in place. That gives the successor leadership a very different incentive structure: they know what happened to Maduro, but they also know that the United States is prepared to deal with them rather than simply eliminate them.

That gets back to your original moral question. Arrest is morally and politically a very different instrument from assassination. A person accused of specified crimes can be apprehended, tried, convicted or acquitted. There is at least the possibility of due process and, importantly, of negotiating with everyone else afterward.

In that sense, I think your idea has a rather interesting progression:

kill the leadership → weaken the organization → perhaps get more tractable successors

versus

arrest the leadership where a genuine criminal case exists → remove the particular individuals → leave a surviving political structure with which one can negotiate.

The second is vastly easier to defend morally. It is also, in some circumstances, probably more useful diplomatically. You don't have to make martyrs, and you don't have to destroy the organization whose behavior you are trying to change.

Venezuela may eventually prove to be a rather important case study in that distinction.
