Decoding Historian Turned Pundit Phillips Payson O’Brien

Phillips Payson O’Brien is a historian who uses the past to strip the romance from the present. His work belongs to a tradition of materialist strategy that treats war as an industrial process rather than a series of heroic maneuvers. That position gives him a particular kind of usefulness right now, when wars in Ukraine and the Middle East keep exposing the gap between how analysts talk about conflict and how conflict actually works.
He frequently attacks what he calls the cult of the map. Traditional military analysts obsess over shifting territorial lines, but in his view a line moving ten miles in either direction is usually a distraction from the structural health of the underlying systems. He treats a tank not as a tactical asset but as a terminal point in a vast production and logistics chain. If the chain breaks, the tank is irrelevant. This lets him ignore short-term battlefield headlines and focus instead on whether a nation can sustain its losses over time.
His analysis of the Russia-Ukraine war, and of potential conflicts involving Iran, centers on systems warfare. Modern war, he argues, is a competition between high-technology production lines. That puts him in a coalition with defense technologists and advocates for cheap, mass-produced autonomous systems. While Washington think tanks focus on the prestige of carrier groups or advanced fighter jets, O’Brien runs the math on interceptor costs versus drone costs. The prestige platform loses that calculation.
That he teaches at the University of St Andrews gives him a specific kind of intellectual autonomy. He is physically and professionally removed from the Washington dinner circuit, where status often depends on not alienating future employers at the Pentagon or at major defense contractors. O’Brien carries none of those obligations. He can be aggressively critical because his career requires neither a security clearance nor a political appointment.
His sharpest and most sustained target is the Institute for the Study of War. He argues that ISW’s daily interactive maps, which track frontline trenches and village-level control, create a false narrative of who is winning. In his view, focusing on the line on the map is a relic of 19th-century military thinking. A side can retreat on the map while winning the war through the destruction of the enemy’s long-term capacity to produce and deploy equipment. He has made this point repeatedly about Russia and Ukraine, arguing that Western analysts misjudged Russian strength before 2022 because they were awed by the size of the Russian army on paper rather than the fragility of its systems.
He also targets the retired general class of commentators. Their experience in counterinsurgency or tactical maneuver leads them, he argues, to overemphasize human factors like will to fight or leadership, which he treats as secondary to the cold math of production. He was particularly vocal in criticizing anonymous Pentagon sources who blamed Ukrainian forces for failing to execute large-scale combined arms maneuvers during the 2023 counteroffensive. Those critics, he argued, ignored the absence of air superiority and treated war as a game rather than a material reality where equipment losses are permanent.
His recent book War and Power extends this critique to the Great Power framework itself. He argues that treating Russia as a Great Power based on landmass or historical reputation is a category error. True power, he claims, is full-spectrum, requiring deep integration of financial, technological, and societal resilience that Russia lacks. The book warns that the West consistently overestimates authoritarian states because it looks at the visible military parade rather than the invisible infrastructure: the sensors, the chips, and the logistics.
He shares more ground with Adam Tooze or Paul Kennedy than with the tactical biographers of generals. The Wages of Destruction by Adam Tooze examines the Nazi economy and argues that Germany was fundamentally mismatched against the industrial power of the Allies, an argument that runs parallel to everything O’Brien has built his career on. The Rise and Fall of the Great Powers by Paul Kennedy explores how economic strength and military commitments must stay in balance, providing the foundation for the idea that imperial overstretch is a mathematical reality rather than a political choice.
The rise of O’Brien reflects something broader in how the public consumes expertise. During the Cold War, the defense intellectual held specialized knowledge of nuclear throw-weights and grand strategy and served as a gatekeeper for that knowledge. The democratization of data, through satellite imagery, shipping manifests, and industrial reports, has changed that arrangement. A historian in Scotland can now challenge a general in Washington by pointing to the same open sources anyone can read.
O’Brien wins status not by proximity to the room where decisions happen but by claiming his model of war predicts outcomes better than the models used by the people inside that room. That claim has made him a figure of authority in the OSINT community and among tech-aligned analysts who treat modern war as a data problem. It has also made him a provocation to traditional defense circles who see his focus on production as deterministic and dismissive of the human art of command. Both reactions, in different ways, confirm that he has found a real pressure point.
In short:
The Washington strategists claim policy expertise.
The retired generals claim operational expertise.
The historians claim historical understanding.
The energy analysts claim market realism.
The restraint camp claims moral prudence.
The journalists claim narrative synthesis.
