The previous articles established that European defense was optimized for deterrence through presence, not warfighting at scale, and the conflict in Ukraine has made measurable what warfighting at scale actually consumes. Artillery shells were expended at rates that exceeded Europe's entire annual production within thirty days of intensive fighting. The geography of the eastern frontier requires detection-to-response capacity across 2,500 kilometers, mobile reserves capable of responding wherever simultaneous pressure materializes, and the infrastructure to move those reserves within hours. The current policy responses, while real and correctly directional, were calibrated to a gap that was already moving when the response was designed, and the gap has continued moving since. Those articles carried an assumption throughout without examining it. The pharmaceutical logistics that sustain forces in the field, the chemical and industrial base from which ammunition is produced, and the food supply chains that keep a mobilized society functional under pressure were all treated as given.
In this article I examine the chemical and industrial layer of that substrate, because it has a structural property the other layers do not share in the same form. The upstream chemistry for shell explosives and propellants, for the antibiotics battlefield medicine requires, and for the synthetic fertilizers European food production depends on shares a common feedstock dependency and a common geographic concentration outside European sovereign control. That is one structural condition expressed through three supply chains, and under conflict conditions, its consequences do not arrive sequentially.
European strategic planning treats three supply chain vulnerabilities as separate problems requiring separate responses. Too many medicines are manufactured in Asia, so Europe needs to reshore pharmaceutical production. The chemical industrial base is contracting under energy price pressure, so Europe needs an industrial competitiveness strategy. Fertilizer inputs are geopolitically concentrated, so Europe needs to diversify agricultural supply chains. Each framing is accurate as a description of the visible surface, and each generates a policy response calibrated to its respective domain, but stops at precisely the layer where the three problems converge into one.
The nitrogen chemistry connection runs through the same industrial processes on both the defense and agricultural sides. RDX and TNT, the main explosive compounds packed into standard artillery shells, both require nitric acid as a central ingredient in their production. Nitric acid is produced from ammonia through a well-established industrial process. Ammonia in turn is manufactured from natural gas through a century-old synthesis on which almost all industrial ammonia production worldwide depends. Natural gas accounts for up to 90% of the variable cost of producing ammonia. Synthetic nitrogen fertilizer, the kind that sustains the crop yields European agriculture depends on, is made through exactly the same process from exactly the same feedstock. These are two downstream applications of the same upstream molecule, competing for the output of the same production capacity.
The supply chain for propellants, the powder charge that fires the shell rather than the explosive that fills it, runs through a different route, though one that leads to the same region. Nitrocellulose, the main component of artillery propellants, is a chemically treated form of cellulose. It is produced by treating cellulose with a mixture of acids, and the raw material for military-grade nitrocellulose is cotton linters, the short fibres left on cotton seeds after the main crop has been processed. Europe sources more than 70% of these cotton linters from China, a figure confirmed publicly by the chief executive of Rheinmetall in 2024. China accounts for nearly half of all cotton linters traded globally, and the primary sourcing region is Xinjiang, which places this dependency in direct tension with the EU's own legislation requiring companies to avoid goods produced using forced labour.
The supply chains for explosive charges and propellants therefore do not represent a single dependency on China but two distinct ones, running through entirely separate commodity pathways, both reaching the same geographic vulnerability via different routes, with the disruption of one doing nothing to address the other.
TNT production adds a third connection, one that links the explosives dependency directly to the broader industrial contraction the subsequent articles examine. Toluene, the petroleum-derived chemical used as the carbon-hydrogen building block for TNT, is a byproduct of the industrial process by which petroleum fractions are broken down into lighter chemicals in large facilities called steam crackers. These are the same crackers that are closing at an accelerating rate across Europe. The industrial contraction that the next articles document as a strategic dependency problem is simultaneously reducing the domestic toluene available for TNT production. The defense production problem and the industrial contraction problem are the same problem viewed from different domains.
The pharmaceutical dependency converges on the same geographic concentration through yet another pathway. India and China together produce between 60 and 80% of the active pharmaceutical ingredients in medicines sold in Europe. Europe's share of global generic active ingredient production by value is approximately 24%, against 66% for the Asia Pacific region combined. 80% of EU active ingredient import volume comes from five countries, with China alone accounting for 45% of that volume. India appears as the available alternative, but approximately 70% of India's bulk drug intermediates, the chemical building blocks used to produce those active ingredients, are themselves sourced from China, rising to 90% for the antibiotic classes known as cephalosporins and penicillins. The geographic vulnerability sits in Chinese industrial capacity regardless of which country's name appears on the origin documentation.
Placed alongside the nitrogen chemistry and cotton linter dependencies, what this produces is a structural condition in which two of the three chains share the same natural gas feedstock through the same ammonia synthesis pathway, and all three share a common geographic concentration in Chinese industrial and agricultural capacity. The dependencies were built separately, through separate market mechanisms, under separate policy frameworks, and under the conflict conditions the defense cluster describes, they fail together.
The energy shock of 2022 demonstrated what this shared upstream structure means in practice as a documented event at European scale. When European gas prices reached levels that made ammonia production uneconomic, the production cuts propagated simultaneously across every downstream application that depends on ammonia. European nitrogen fertilizer production fell by approximately 70% at the peak. Yara, one of Europe's largest fertilizer producers, ran its European ammonia capacity at 35% of normal. Grupa Azoty, Poland's largest chemical company and the second-largest fertilizer producer in the EU, cut ammonia output to 10% of capacity.
The carbon dioxide produced as a byproduct of ammonia synthesis fell at the same time, causing concurrent shortages in food processing, medical applications, and industrial gas supply. The production cuts expressed themselves across all of them at once, because all of them depended on the same upstream molecule whose production had become uneconomic.
This was an unmanaged concurrent failure across every application dependent on the same upstream input, triggered by a gas price movement in peacetime, with full market alternatives still available and no active supply disruption. Under conflict conditions, where gas supply may be physically constrained, where market alternatives are inaccessible, and where the demand from ammunition production, food supply, and battlefield medicine is simultaneously elevated, the same mechanism operates faster, more completely, and without the partial cushioning that market flexibility provided in 2022. The event demonstrated the present structural condition.
Understanding how this condition was created is necessary to assess whether the responses it has generated can address it, because the condition was not produced by market forces alone, and the way it was produced determines whether the institutions now responding to it are capable of reaching its structural depth.
Asian manufacturers competed into generic pharmaceutical and bulk chemical manufacturing through the 1990s and 2000s on cost advantages that European producers could not overcome. Each European exit was individually rational within the competitive logic it faced, while European governments operating through this period had no strategic reason to counteract these market dynamics, because the geopolitical framework European strategic thinking had organized itself around treated the offshoring as desirable. That framework, known in German as Wandel durch Handel, meaning transformation through trade, held that deepening economic interdependence generates political stability rather than strategic exposure. Deepening reliance on Chinese chemical and pharmaceutical production was an interdependence being constructed.
The same logic that justified the gas pipeline to Russia justified the pharmaceutical supply chain to China, the cotton linter dependency on Chinese agricultural processing, and the accumulated concentration of upstream chemistry in geographies that the framework defined as partners rather than risks. The post-war settlement, the integration of Eastern Europe, and the gradual moderation of trading relationships all gave the doctrine genuine intellectual foundation over decades of apparent confirmation, and it is precisely that accumulated credibility which made the framework self-insulating against the signals that should have challenged it.
The more comprehensively a successful strategy has organized investment commitments, institutional assumptions, and professional identities around its continuation, the more a contradicting signal tends to be absorbed as an anomaly to be managed rather than registered as a reason to question the framework itself.
February 2022 tested the assumption underlying that strategic framework in the energy domain and it failed. The chemical and pharmaceutical layer is where the same failure is working its way through, more slowly and less visibly, through the same mechanism. The supply chains that exist today are the Wandel durch Handel paradigm expressed in industrial capacity rather than pipeline infrastructure, built deliberately under a logic that has since failed, made structurally difficult to reverse, and now carrying strategic costs whose full scale the policy response has not yet stated plainly.
What matters for the argument the cluster examines is not only that the dependencies exist, but that the decision-making processes and governance design now constructing the response to them is the same that created them, operating from within the same organizational logic and subject to the same structural limits on what it can see.
The responses this condition has generated share a common boundary they do not cross. The EU's Act in Support of Ammunition Production addressed final assembly and filling capacity without addressing the upstream chemical chain whose availability determines whether that capacity can actually run at the rates a sustained conflict would demand. The Critical Medicines Act, proposed in March 2025, agreed at Council level in December 2025, and passed by the European Parliament in January 2026, addresses final-stage pharmaceutical manufacturing and procurement reform without reaching the key starting materials and chemical intermediates where the dependency actually originates. The EU Chemicals Strategy addresses the competitiveness framework without reaching the energy price disadvantage that is driving factory closures. The tariffs on Russian and Belarusian fertilizers address import diversification without addressing the natural gas feedstock dependency that makes European production uncompetitive when gas prices rise.
Four separate policy domains, four responses that address what became politically visible, and none that reaches the structural root. This is the predictable output of decision-making processes within a governance design that responds to the visible layer of a problem because it has no reliable mechanism to see the structural depth beneath it, and that optimizes the components it can see while the system conditions those components depend on are left unaddressed.
The case that makes this most concrete involves a name and a financial trajectory. Grupa Azoty, Poland's largest chemical company, is the entity whose subsidiary Prozap is engineering the expansion of Nitro-Chem's TNT production capacity, the primary European response to the explosives bottleneck. Grupa Azoty has reported continuous quarterly losses since late 2022 and operates under repayment deferral agreements with thirteen financial institutions. In March 2026, the same period in which the TNT expansion was announced, it suspended all new nitrogen fertilizer orders because gas prices had risen again to levels that made production uneconomic.
The company responsible for engineering Europe's explosives capacity expansion is itself a casualty of the upstream gas dependency that the expansion is supposed to help address. Building a new TNT production line does not resolve Europe's explosives bottleneck if the company providing the engineering for that line cannot sustain its own ammonia production when gas prices rise.
The same pattern holds across every domain the cluster examines. A new European active ingredient manufacturing facility that sources its critical intermediates from the same Chinese industrial geography that a conflict has made inaccessible faces the same structural problem as a propellant production line that cannot source its cotton linters because the upstream supply has been disrupted. In each case, the response has moved the visible layer of the problem closer to home while the upstream constraint remains where it was.
What this means for the warfighting question Articles 4 through 7 raised is that the military capability gap is not the only gap, but is the gap that makes the others consequential, and the others determine whether closing the military gap produces the outcome the defense cluster requires.
For Europe to be capable of fighting, sustaining, or prevailing in the potential conflict those articles describe, three structural conditions would need to exist that do not currently exist.
Europe would need sovereign upstream chemistry at the volumes wartime demands. Not final-stage shell filling or pharmaceutical tableting, but the nitric acid, propellant powder, bulk drug intermediates, and nitrogen compounds that determine whether any downstream production can function when the upstream is disrupted. The upstream nodes that are currently either absent from European territory or financially fragile would need to be rebuilt within genuinely allied geographies under conditions that cannot be shut off by a political decision made in Beijing or Moscow.
Europe would need industrial capacity sized for concurrent wartime demands across all three supply chains at the same time, not for peacetime efficiency in any one of them separately. A Europe that produces two million artillery shells in a good year while the same chemical base must simultaneously supply fertilizers for 450 million people and antibiotics for a mobilized healthcare and battlefield medical system has a capacity problem that no single policy response in any one of those domains is designed to address.
And Europe would need the critical upstream dependencies decoupled from adversarial political control on a timeline that Europe, not its adversaries, determines. Cotton linters from Xinjiang, pharmaceutical intermediates from Chinese industrial clusters, and fertilizer nutrients from Russian and Belarusian producers who understand that supply is leverage are not only commercial vulnerabilities. They are political instruments whose availability can be withdrawn at a moment of the supplier's choosing. The structural requirement is not only to reshore or rebuild, but to do so before the political decision to weaponize the dependency is made, which is a shorter timeline than any currently announced European policy is working toward.
The military capability gap the defense cluster established as already insufficient assumes a pharmaceutical, chemical, and agricultural substrate that can be sustained under the conditions those articles describe. The 2022 curtailment demonstrated, at European scale and in peacetime, what happens to that substrate when the upstream is disrupted. Closing the military capability gap while this substrate fails under conflict conditions does not produce the outcome the defense cluster requires. The gap is larger than the military analysis alone can see.
