On 1 June, in Vilnius, NATO’s deputy secretary general told the Parliamentary Assembly what next month’s summit in Ankara is for. “Ankara will be about turning cash into combat-ready capabilities,” Radmila Shekerinska said, “significantly scaling up our defence industries, and strongly supporting Ukraine.” Ten days earlier, in Helsingborg, the secretary general had reached for almost the same words: allies must turn the five-percent commitment into military capability.
The alliance has named its problem precisely. The phrase that keeps recurring — turning cash into capabilities — concedes that the two are not the same thing, and that the conversion is where the difficulty sits. Where NATO’s leaders and a pair of independent studies part company is on what kind of task that conversion is. The summit frames it as something that enough spending and reform will accomplish. Two studies published this spring — by methods that share nothing — describe it instead as something the alliance’s structure keeps reproducing, that spending raises but does not close.
In a month, heads of state and government meet in Ankara to mark the road to five percent of GDP on defence. The figure is real: the money is being committed, procurement lines are moving, the political weight behind the number is genuine. Nothing here disputes that. What it disputes is whether “turning cash into combat-ready capabilities” is a task that finishes — or a gap that the budget, by itself, cannot reach. Two studies, set side by side, say the second. One is a survey; the other a structural diagnosis; they come from people who do not work together, and they land on a single account of where European militaries actually stand. That agreement — not either study alone — is what deserves a summit’s attention.
Two instruments, no shared method
The first study is EDINA V, the fifth edition of a cross-national defence-readiness survey published by Defcom One, the consultancy run by Christian Mölling with Torben Schütz and Theresa Caroline Winter. It runs across eighteen European NATO members and scores them on defence spending, personnel, industrial capacity, and doctrinal adaptation. Its title states the conclusion without ornament: Defence Hardware Surge, Readiness Gap — Why Money Alone Won’t Deliver Capability. This is empirical work in the ordinary sense — indicators, a structured comparison, states measured against each other on what they can actually field.
The second study is Consensus as Ceremony, a structural diagnosis of NATO’s coordination architecture. It surveys no one. It rests on a published proof about how coordinated power is produced and lost, and on a model that applies that proof to this alliance — the model documented but held closed, the proof beneath it open. Where EDINA counts and compares, the structural analysis asks what the architecture can and cannot do at the speed the environment now demands, and reads the readiness condition off that.
These are not two readings of one dataset. They share no source for the claim that matters. Either could have been written if the other did not exist. A survey reaches its result by asking eighteen states the same questions and tabulating the answers; a structural proof reaches its result by deriving what a given configuration must produce. The two roads do not touch — until they arrive at the same place.
And the place they arrive at is specific. Both find a readiness gap. Both locate it below the level at which money and management operate. Both read the same near-term exposure in Europe’s dependence on capability it does not own. EDINA reaches this by measurement; the structural model reaches it by derivation. The overlap is not in the vocabulary — it is in the finding.
Why the agreement is the argument
Start with the ordinary worry about any single study: that the result is an artefact of the method. A survey can write its conclusion into the way it frames its questions. A model can write its conclusion into its assumptions. Each instrument carries its own characteristic way of being wrong, and a careful reader discounts for it.
The two instruments here do not share a way of being wrong. A questionnaire and a derivation cannot produce the same artefact, because whatever would bias the one has no grip on the other. When they converge, the convergence rules out that the shared finding is an artefact of either method. Subtract instrument-error from both sides, and what remains is the part that is about the world.
This is a narrow claim, and it is worth keeping narrow. Two independent instruments agreeing does not put a finding beyond doubt. It removes one large family of doubts — the suspicion that the result lives inside the tool that produced it. That alone changes what the agreement weighs. A gap reported by EDINA by itself is a survey result, open to every question one asks of survey design. A gap reported by EDINA and reproduced, independently, by a structural derivation is a property of the thing being measured. The doubt that remains is real, but it is no longer the doubt that the number is an artefact.
So the question stops being whether the readiness gap exists. Both instruments find it. The question becomes what it is — and on that, the two studies say the same thing about where it lives.
Where the gap actually sits
Readiness has a layer structure. There is an operating layer — force generation, logistics, command arrangements, the parts a reform programme can reach inside a planning cycle. Beneath it runs a slower layer: the demographic base from which armies recruit, and the rate at which money turns into deployable force rather than signed contracts. Both studies put the source of the gap in that lower layer.
The demographic floor moves on a timescale no budget changes. The conversion gap — the distance between what is spent and what can be put in the field — is a property of how procurement, industry, training, and sustainment fit together, and it does not close because the top line rises. EDINA’s own data carries the symptom: a surge in hardware spending, and a readiness number that does not move with it. The survey records that this is happening. The structural diagnosis names why — the source sits one layer below where spending and operating-level reform do their work.
A second feature shows up on both sides: the doctrinal split on drones. The cheapest, fastest-moving capability of the current war is the one on which European forces are least aligned, and the disagreement there is not about money. It is about how to fight. That is a deep-layer problem wearing an operating-layer costume, and no procurement budget settles it.
There is precedent for this inside the alliance’s own recent history. After 2014, NATO turned from expeditionary posture back toward territorial mass. Declared commitments rose. Deployable readiness lagged behind them — and somewhere in that lag the meaning of the word readiness drifted, from what could be sent to what had been promised. The conversion gap is that same divergence, this time named and measured rather than noticed after the fact.
What spending reaches, and what it does not
None of this makes spending a mistake. Money raises the floor; it is necessary; without it the gap is worse, not better. The point is reach, not merit. Operating-layer reform — better allocation, integrated command, synchronised procurement, recruiting expertise brought in from outside — manages the gap. It does not close it, because the source is one layer down from everything reform can touch.
There is a sharper edge here, and both studies find it too. Part of what counts today as European deployable capability is not European. It rests on enabling functions — strategic lift, intelligence, surveillance, the command backbone — that the United States supplies at its own discretion. Under a change in US engagement, that capability does not fade slowly. It moves out of reach faster than European reform can stand up a replacement. The five-percent figure is measured against a baseline that quietly includes capacity Europe does not control. The gap that Ankara’s number is meant to close is, in part, a gap the number cannot see — because the thing it would have to buy is currently on loan.
The gap is also not one quantity. It is three. EDINA’s cross-section and the structural reading both resolve into regional outputs of a single condition: the eastern flank, the centre, and the south sit in distinct positions — different exposure, different industrial base, different distance from the enabling capacity that may or may not stay. One architecture, three readiness gaps, and no single move closes them together. A figure agreed in Ankara as a share of GDP flattens that into one line on a chart. The force it stands for does not flatten.
The architecture under the number
Why a structural diagnosis, and not just a better survey? Because the readiness gap is the visible face of something the survey is not built to see: the way the alliance is put together.
NATO runs three orders at once — what it declares, how it operates, and what has settled into its structure over decades — and these three drift apart at different speeds. The machinery that makes the alliance durable is the same machinery that makes it slow to adapt; past a certain tempo, durability and rigidity become the same property seen from two sides. The bypasses that once absorbed internal ruptures, the Defence Planning Committee among them, have been let go. Readiness, in this reading, is not a number a member state owns and improves on its own. It is an output of how thirty-two of them coordinate, under time pressure, with an enabling layer they share unevenly and do not all control.
That is why the gap holds independent of any one government’s effort, and why it returns after each round of reform. It is not a verdict on whether Germany, or Poland, or any member is trying. It is a property of the configuration they are trying inside of. The survey shows that the gap is there and the same shape across very different states; the structural analysis explains why a problem that looks national keeps coming out alliance-wide.
What Ankara inherits
Set the two studies down and the shape that remains is not an argument about whether Europe spends enough. It is a question about what Europe is counting.
The five-percent commitment measures an input — budget as a share of national wealth. The readiness gap is an output property — deployable force, net of the conversion losses and the borrowed capacity that the input figure folds out of view. A summit can raise the input and report progress while the output it was meant to stand for moves the other way. That is not a failure of will in Ankara. It is a measurement mismatch, and it is structural: the instrument the alliance uses to mark its own seriousness reads a different quantity from the one that decides whether the force can fight.
Here the two studies part, on the single question that decides what follows. EDINA reads the gap as an execution deficit — closable, given the right operating-layer reforms — and Mölling and his co-authors flag the limits themselves: high spending need not yield capability, and some of the binding constraints are trade-offs rather than shortfalls. The structural diagnosis takes those limits to their conclusion. If the source sits in the demographic floor and the conversion rate, both fixed on a policy timescale, the gap is something the alliance’s architecture keeps producing — managed by reform, not removed by it. Same evidence, a different verdict on whether a fix exists. The disagreement is honest, and it is the one worth having out loud.
What neither study offers is an instruction to a government. That is not reticence; it is the edge of what a diagnosis carries. The two instruments jointly support a reading of where the gap sits and what reaching its source would take. They do not support a procurement list, and printing one would trade the warrant they earned for an opinion they have not.
So the inheritance is a question, and it is addressed to the level where the measuring is done — ministerial, and alliance. An adversary calibrates deterrence against deliverable force, not against spending levels or reform announcements. Shekerinska’s phrase is the right one: Ankara is about turning cash into combat-ready capabilities. The two studies only add what the phrase leaves out — that the conversion runs through a layer a summit does not reach, and that the gap which results is managed there, not removed. Ankara will produce a number that is real. Whether it also produces the force the number is meant to stand for turns on which of the two the alliance has been measuring all along. That is what the summit hands forward; the budget, by itself, cannot answer it.
