Napoleon vs. the Duke of Wellington on Regime Change: Why These Two, and Why Now
One man exported regime change to a dozen countries. The other built the international order to stop him. Now they disagree about Iran.
A behind-the-scenes look at the debate, the sources, and why they took the positions they did

Why This Topic
On February 28, 2026, the United States and Israel launched nearly nine hundred airstrikes in twelve hours against Iran. They killed the Supreme Leader. They stated openly that their goal was regime change. One month later, the Strait of Hormuz is closed, twenty thousand sailors are stranded at sea, the Gulf states are taking Iranian missiles, and Iran has rejected a fifteen-point American peace proposal as maximalist and unreasonable while counter-proposing that it receive sovereignty over the world’s most important oil shipping lane.
The surface question is whether this specific military operation was wise. The deeper question is the one that has been running underneath international relations for three hundred years: does any external power have the right to remove a government it finds threatening, dangerous, or simply bad, and call that removal liberation? That question has a long history of being answered by people with guns and then litigated by people with philosophy. We thought we should let the philosophers have first crack this time.
The Iran war is not just a foreign policy dispute. It is a live test of two irreconcilable theories about how power, legitimacy, and international order are supposed to work. And those two theories have been arguing with each other since before Napoleon was born.

Why Napoleon
Napoleon Bonaparte is the most instructive case study in the history of externally imposed regime change, because he both theorized it and practiced it at industrial scale. He replaced the governments of Italy, the Netherlands, Spain, Westphalia, Naples, and a half-dozen other territories with varying degrees of popular support and varying degrees of bayonet. He justified every instance of it using the same language that has been used about Iran: the existing government is illegitimate, the people deserve better, the external power is delivering what the people cannot yet deliver for themselves.
What makes Napoleon genuinely useful here, rather than just provocative as a casting choice, is that he believed it. His letters from Saint Helena, written after everything had collapsed, show a man who still thought the Napoleonic Code was worth the five million dead. He wrote in his memoirs that he saw himself as completing the French Revolution by spreading its principles to populations that were suffering under feudal monarchies. He was not performing this argument. He held it. That makes him a far more interesting debate partner than someone who intervenes for purely cynical reasons and knows it.
There is also the specific mechanism of his fall that matters here. Napoleon was removed by a coalition of every major European power acting together because no single power could stop him alone. That coalition then sat down at Vienna and designed a new international order specifically to prevent anyone from ever doing what Napoleon had done again. The man who built that order is the man across the table.

Why the Duke of Wellington
Arthur Wellesley, the Duke of Wellington, was not just the general who defeated Napoleon at Waterloo. He was, in many ways, the chief architect of what came after. He was a principal figure at the Congress of Vienna in 1814 and 1815, the gathering that produced the Concert of Europe, which was the first serious attempt in Western history to build a rules-based international order among great powers. The core principle of that order was the one Wellington argued for in the debate: sovereign states, however imperfect, are not subject to unilateral removal by outside powers. Great powers manage their conflicts through collective diplomacy, not through one of them deciding that another government needs to go.
Wellington held this position not as an abstraction but as the hard-won conclusion of a man who had watched Napoleon’s liberation of Europe produce approximately two decades of war and millions of casualties. His memoirs and letters are full of a particular kind of conservatism that is easy to caricature and hard to argue with: he believed that existing institutions, however flawed, embody a kind of accumulated stability that no reformer can replicate overnight, and that the chaos of destroying them is almost always worse than the imperfections of tolerating them.
The detail that grounds him most specifically in this debate is his famous remark, made later in his political career, that the whole point of the Concert of Europe was to prevent any single power from acting as the world’s policeman. He did not think that was a role that produced good outcomes. He had spent fifteen years fighting the man who thought it did.

Who Else We Considered
Edmund Burke was the obvious first alternative. Burke wrote Reflections on the Revolution in France in 1790, which is essentially a two-hundred-page argument against externally imposed change of any kind, and his debate with Thomas Paine is one of the most direct clashes in the history of political philosophy. We held Burke back partly because we have already used him in our British decline debate with Paine, and partly because Burke never had to defend his position against someone who had actually done the thing he was criticizing. Wellington had. That gave the Wellington casting a specificity that Burke could not match.
Immanuel Kant was genuinely considered. His essay Perpetual Peace, written in 1795, contains one of the clearest statements in the philosophical literature that no state has the right to interfere in another’s constitution or government. It is a categorical argument, not a pragmatic one, and Kant would have been devastating in the Wellington role. We went with Wellington instead because Kant’s argument is purely theoretical and Wellington’s is backed by the experience of having fought the intervention and then designed the alternative. The debate needed someone who had skin in the game.
Woodrow Wilson was on the table as Napoleon’s partner rather than Napoleon himself. Wilson’s Fourteen Points and his theory of self-determination overlap substantially with Napoleon’s justification for intervention. We decided Wilson’s framing is too recent and too specifically American to carry the philosophical weight the debate needed. Napoleon operating at continental scale and across a longer historical arc felt like a more productive source of tension with Wellington.
Theodore Roosevelt was briefly considered as Wellington’s debate partner rather than his opposition. Roosevelt and Wilson had already appeared in our previous Iran debate. We wanted new voices.

Why Each Man Takes the Position He Does
Napoleon’s support for the Iran intervention follows directly from what he wrote and said about his own campaigns. In his memoirs, dictated at Saint Helena, he consistently framed his military operations as a liberation project: he was delivering the principles of the French Revolution, specifically legal equality, to populations that were suffering under governments they had not chosen and could not remove. The Iranian situation maps onto that framing almost precisely. A population in the streets. A government with no democratic mandate. An external power with military capability and ideological justification. Napoleon would have recognized the structure immediately and approved of it.
The place where Napoleon’s argument gets genuinely complicated is the nuclear dimension. His campaigns did not involve weapons of mass destruction. But in his Maxims of War and in his correspondence with his generals, he wrote repeatedly about the importance of neutralizing existential threats before they could be deployed. He was a pre-emptive actor by instinct. The argument that an Iranian nuclear weapon in the hands of a proxy organization constitutes an existential threat to a neighboring country is precisely the kind of argument Napoleon would have used to justify action, because he used structurally identical arguments repeatedly in his own career.
Wellington’s position is rooted in something more specific than general conservatism. After Waterloo, he spent years at Vienna watching diplomats try to put together a framework that would prevent the previous twenty years from happening again. He came out of that experience convinced that the most dangerous thing in international relations is a power that believes its own moral justifications strongly enough to act on them unilaterally. His letters from that period describe his deep skepticism of any arrangement that allowed one country to decide, on its own, that another country’s government was illegitimate.
The concession Wellington makes in the debate is real and historically authentic. He does not argue that the Iranian regime was good. His position is not that bad governments should be preserved. His position is that the mechanism of removal matters as much as the outcome, and that unilateral military removal produces consequences that cannot be controlled once started. He was willing to say, as he did in the debate, that the case for intervention is not without force. He just believed the practice consistently fails to match the theory. The current state of the Strait of Hormuz, the stranded sailors, and the fifteen-point peace proposal that Iran called unreasonable before issuing its own five-point demand for sovereignty over the strait is the evidence Wellington would have pointed to.

A Note on the Sources
The two richest primary sources for Napoleon’s voice are his Maxims of War, which he compiled himself, and the Memorial of Saint Helena, which is the record of his conversations during his final exile as taken down by the Count of Las Cases. The Memorial is a remarkable document because it shows Napoleon in full retrospective mode, consciously constructing the narrative of his own career and defending every major decision he made. He is eloquent, self-serving, frequently brilliant, and almost entirely unrepentant. The line in the debate about the casualty figures being a temporary inconvenience compared to the lasting significance of the Napoleonic Code is not a caricature. It is a compression of arguments he actually made.
For Wellington, the most useful primary sources are his dispatches, collected in a multi-volume edition that covers his campaigns from India through Waterloo, and his later political speeches in the House of Lords. Wellington in the Lords is a different creature from Wellington in the field: precise to the point of pedantry, deeply suspicious of enthusiasm in any form, and capable of delivering a sentence that sounds mild and lands like a poleaxe. His remark in 1830 that the existing system of representation in Parliament was perfect and required no reform, which he made approximately eighteen months before the Reform Act riots broke his windows, gives you the texture of his political voice: absolute conviction delivered with total composure.
The detail about the windows is worth keeping in mind. Wellington’s conservatism was not cost-free, and he knew it. He paid political prices for his positions throughout his post-military career. That makes his argument in the debate something more than pure principle. He had watched the alternative to managed stability, in the form of Napoleon’s Europe, and he had also watched what happened when you refused to manage change at all, in the form of the mob outside Apsley House. He was operating from experience in both directions.
