Clausewitz vs. Jomini on Boyd's Legacy: Why These Two, and Why Now
A behind-the-scenes look at the debate, the sources, and why they took the positions they did
Why This Topic
John Boyd died in 1997 and has been either a visionary prophet or a vastly overrated briefer ever since, depending entirely on who you ask. The argument about his legacy has never really settled. The OODA loop is on slides in every branch of the American military, in business schools, in sports analytics, and apparently in competitive gaming circles. The Marine Corps warfighting manual bears his fingerprints. The F-16 exists partly because he fought for it. And yet Afghanistan ran for twenty years and Iraq became a case study in what happens when you win the operational campaign and have no idea what comes next.
That gap between Boyd’s reputation and the actual outcomes produced by his ideas is the philosophical question underneath the current events. Was he a genuine strategic thinker whose framework was misapplied by lesser minds, or was the framework itself incomplete in ways that made misapplication inevitable? That is a question worth having a debate about, and it is a question that two nineteenth-century military theorists are, paradoxically, better positioned to answer than Boyd’s contemporaries would be. They can look at the ideas from outside the institutional loyalty that still clouds the argument.
We also chose this topic because Boyd is just past our hundred-year rule — he died in 1997, which means he stays off the stage. But his ideas are old enough to examine seriously, and the wars that tested them are far enough in the past that honest accounting is possible.
Why Clausewitz
Carl von Clausewitz is the obvious choice for this debate, almost uncomfortably so. Boyd built his framework partly in reaction to what he saw as the Clausewitzian legacy in American military thinking, specifically the tendency to treat war as a problem of attrition and mass rather than speed and psychological collapse. Clausewitz is the establishment Boyd was arguing against, which makes him the ideal skeptic.
But the more interesting reason to use Clausewitz is his central argument in On War: that war is the continuation of politics by other means. That single idea is the most devastating critique available of Boyd’s legacy, and it does not require any distortion of Clausewitz’s actual position to deploy it. Afghanistan and Iraq were not failures of tactical or operational doctrine in the first instance. They were failures of political clarity. No OODA loop speed, no maneuver warfare elegance, solves the problem of a war whose political objective cannot be defined. Clausewitz wrote that in 1832 and the American experience from 2001 to 2021 illustrated it at enormous cost.
The primary sources are On War, which Clausewitz left unfinished at his death in 1831 and which his wife Marie compiled and published. The tension between his earlier, more schematic writing and the more nuanced later books is real and worth acknowledging — the famous friction and fog passages are in the later material, which is also where his thinking is most developed and most directly applicable to the Boyd argument.
Why Jomini
Antoine-Henri Jomini is a less obvious choice but a more interesting one than he first appears. He is usually cast as Clausewitz’s foil, the man who believed war could be reduced to geometric principles while Clausewitz understood its irreducible complexity. That framing is not wrong, but it flattens him.
What makes Jomini specifically useful for this debate is his relationship to Boyd’s actual ideas. Boyd’s framework attacks Jominian thinking directly — the whole point of maneuver warfare doctrine is to replace the geometric, position-focused, principle-driven approach that Jomini represents with something more fluid, adaptive, and oriented toward psychological collapse. Jomini is not just a general skeptic of Boyd. He is the specific intellectual tradition Boyd was trying to overturn. Putting him in the debate means Boyd’s critique of geometric thinking gets tested against the best version of what it was criticizing.
There is also something genuinely funny about Jomini’s position in this debate. His The Art of War was the primary military education text for American officers through the Civil War and beyond. Union and Confederate generals had both read him. His influence on American military thinking was enormous and lasted well into the twentieth century. The argument that Boyd was fighting Jominian doctrine without knowing it — or while refusing to credit it — is historically plausible and dramatically productive.
The historical antagonism between Clausewitz and Jomini was real. They served in the same era, were aware of each other’s work, and reached opposite conclusions about whether military success could be systematized. Clausewitz thought Jomini’s principles were seductively clear and fundamentally misleading. Jomini thought Clausewitz was a philosopher who had mistaken complexity for depth.
Who Else We Considered
Sun Tzu was the first alternative we looked at seriously. Boyd drew explicitly on Sun Tzu, which creates a natural setup for Sun Tzu to claim that Boyd was just translating The Art of War into American military vocabulary and getting far too much credit for the translation. The problem is that Sun Tzu’s historical record is thin enough to create real constraints on what he can credibly argue in detail. The text is also aphoristic in a way that makes extended analytical debate difficult to sustain. He works better as a reference point than as a debater.
Giulio Douhet was attractive because both he and Boyd were air-focused thinkers who reached completely opposite conclusions. Douhet believed air power won wars by destroying civilian will through strategic bombing. Boyd believed psychological collapse could be achieved through speed and disorientation without mass destruction. The problem is that Douhet died in 1930, which puts him just inside the hundred-year window, and the debate risks becoming too narrowly focused on air power doctrine rather than the broader legacy question.
Billy Mitchell was the American Boyd before Boyd in some ways — a prophet of air power who was court-martialed for his trouble, vindicated partially by events, and celebrated in retrospect more than he was heard in his lifetime. The parallel with Boyd is almost too neat, and Mitchell died in 1936, which is inside the window. We held this pairing back for a potential future episode on whether the American military has a structural tendency to punish visionaries and whether that tendency has gotten better or worse.
Alfred Thayer Mahan was briefly considered as a representative of the institutional military thinking Boyd was reacting against, but Mahan’s focus on naval power and sea control made the connection to Boyd’s ideas too indirect to generate productive debate without a lot of setup.
Why Each Man Takes the Position He Does
Clausewitz’s skepticism of Boyd’s legacy flows directly from his core intellectual commitment. On War is fundamentally a book about the relationship between military action and political purpose. The famous trinity of war — the people, the military, and the government — is Clausewitz’s framework for understanding why military operations cannot be understood in isolation from the political context that produces and directs them. Boyd’s OODA loop, taken as a complete theory of war, has nothing to say about that relationship. It tells you how to make better decisions faster. It does not tell you what decisions to make or whether winning the engagement advances the political objective. For Clausewitz, that omission is not a gap in Boyd’s framework. It is the framework’s defining limitation.
Clausewitz also concedes what he cannot honestly deny. Energy-maneuverability theory was real science that produced a better aircraft. The Marine Corps warfighting manual is a good document. The OODA loop as a training heuristic has genuine value. These concessions are historically authentic because Clausewitz’s argument is not that speed and decision cycles are irrelevant — it is that they are insufficient. He can be generous about Boyd’s tactical contributions precisely because his criticism operates at a different level.
Jomini’s position is more personal and more specific. Boyd’s maneuver warfare doctrine is a direct attack on the geometric, principle-based approach to war that Jomini spent his career documenting and defending. The seven principles of war — objective, offensive, mass, economy of force, maneuver, unity of command, security — are exactly what Boyd’s disciples were arguing against when they pushed for speed and decentralized initiative over concentration and geometric clarity. Jomini’s critique of Boyd is therefore not just intellectual disagreement. It is institutional and professional.
Where Jomini concedes ground, he does so carefully. The F-16 argument — that Boyd correctly identified a procurement failure — is genuine because Jomini’s principles say nothing about procurement politics. The Marine Corps warfighting manual concession is genuine because a document that teaches officers to exploit disorder is compatible with geometric operational planning at the campaign level. What Jomini will not concede is that Iraq and Afghanistan validate Boyd’s framework. His argument is that both wars failed partly because Boyd’s doctrine gave officers permission to bypass enemy formations rather than destroy them, which created the conditions for insurgency. Whether that argument is correct is a genuine historical debate. That it is Jomini’s authentic position, derived from his actual principles, is clear.
The most interesting moment in the debate is when both men discover they agree Boyd was overrated and immediately realize they agree for incompatible reasons. Clausewitz thinks the missing piece was political clarity. Jomini thinks the missing piece was geometric discipline. These are not supplementary criticisms. They represent fundamentally different understandings of what strategy is and where it operates. The Boyd debate becomes the occasion for the argument they were always going to have.
A Note on the Sources
Clausewitz’s primary source is On War, specifically the later books where his thinking is most developed. The fog of war and friction passages are in Book One. The political dimension argument runs through the entire work but is most explicit in the famous opening definition. We relied on the Howard and Paret translation, which is the standard modern English edition and substantially more readable than older versions.
Jomini’s primary source is The Art of War, published in 1838, which is available in full and is genuinely readable by modern standards — considerably more accessible than On War, which supports one of Jomini’s biographical jokes in the debate. His Summary of the Art of War is the more concise version of the same argument and the one that most influenced American military education through the nineteenth century.
For Boyd himself, the primary sources are unusual. Boyd never published a book. His ideas exist in a series of briefings — Patterns of Conflict, Organic Design for Command and Control, The Strategic Game of Question and Answer — which were delivered in person, often for hours at a time, and exist in reconstructed slide form. Robert Coram’s biography Boyd: The Fighter Pilot Who Changed the Art of War is the most comprehensive secondary source and the basis for most of the biographical detail in the debate, including the Fighter Mafia, the forty-second Boyd claim, and the institutional resistance he faced throughout his career.
What Comes Next
This is a two-part debate. Part 1 covers Boyd’s actual record — the fighter pilot, the energy-maneuverability theory, the F-16, the steelmanning, and the core critique. Part 2 takes Afghanistan and Iraq as evidence, examines whether the military absorbed Boyd’s substance or just his vocabulary, and ends where these debates always end, which is with two men who agree on the verdict and are furious about everything else.
We have been looking at several other military and strategic pairings that the Boyd debate opens up naturally. The Billy Mitchell question — whether the American military has a structural problem with visionaries — is one we want to return to when we have the right pairing. The broader question of whether counterinsurgency is even a coherent military doctrine is another.
