“Battles are fought in the trenches but won in the factories,” is a quote often attributed to Joseph Stalin, and whether he actually said it or not is of less importance. Its permanence is based on a deeper strategic truth: wars are never decided solely where they are fought, but also where societies produce, move, and store resources. This is not a new insight; Admiral Eccles argued in 1958 that logistics is the link between civilian production resources and the fighting forces for the needs of national defense. Throughout history, the construction of roads and ports (later also railways and airports) has been crucial in enabling both effective military movement in wartime and trade in peacetime, a foundation for preparedness and resilience.
In the age of total war, this logic becomes inevitable. Modern conflicts are decided not only by armies on the move, naval power and air supremacy, but also by economic strength, industrial capacity, logistical cohesion and the cooperation of alliances. Behind all this lies something even more fundamental, namely demographics. Age structure, gender balance, human capital, depth of skills and population size determine not only who can fight but also who can invent, build, repair and transport. The demographic profile of a country, including that of its allies, is the basis of both military capability and societal resilience.
At the same time, the line between peace, crisis and war has blurred. Recent decades have shown that societies can be attacked long before open war breaks out. Energy systems, transport corridors, industrial supply chains, healthcare capacity and the psychological stability of the population have become legitimate targets for strategic influence. Therefore, preparedness is no longer a state of emergency but a continuous state. In such an environment, future conflicts are decided less by the balance of power at the outbreak of war than by the country's ability to maintain and strengthen its military power through industrial production and innovation. Victory belongs to those who can quickly increase production, develop new technology under time pressure and convert economic robustness into military operational capability. The decisive battlefield is therefore not at the front, but in the systems that allow a society to mobilize its resources and adapt under unstable conditions for long-term survival.
Against this background, it is no coincidence that the Nordic countries presented a joint strategy for transport preparedness in March 2026. This marks a shift, security is no longer seen only as a matter of national borders but as an integrated infrastructural ecosystem that must function even in the event of serious disruptions or war. The strategy identifies four transport corridors whose operational integrity is crucial for the supply of civil society, military mobility and the possibility of allied reinforcement in war. The strategy can be seen as a first step towards a coordinated development of the infrastructure to meet the common needs of both defense and industry.
Sweden has already been designated as the Nordic logistical hub, the land bridge through which Nordic and transatlantic reinforcements must pass, and the link that connects military movements with industrial supply chains to achieve societal robustness and resilience. This means that Sweden is no longer an actor among others, but the geographical and infrastructural node for the resilience of the entire region. The joint strategy formally confirms this insight.
For generations, the Nordic countries lived with the illusion that the nature of geography was a protection in itself: the Baltic Sea as a moat, the Arctic as an impenetrable border and the forests of Norrland as a natural barrier. The joint Nordic planning now assumes that these truths no longer apply and that Sweden will become NATO's logistical backbone on the northern flank.
But this insight also reveals uncomfortable truths. Beneath the surface, the Nordic infrastructure is far more fragile than the strategic ambitions built on it. An aging railway, strained road networks and decades of neglected maintenance have created a system with a lack of redundancy. With minor variations, the situation is similar and strained in all the Nordic countries. Several of the most important corridors contain bottlenecks where the loss of a single bridge or tunnel can limit transport and, in the worst case, knock out the entire logistical link. The floods in Västernorrland were a clear example of the system's sensitivity, where several secondary problems and shortcomings were identified. Repair resources were insufficient and agreements were lacking. The forestry department had not analyzed the consequences of clear-cutting in connection with major transport routes, which led to larger water flows and landslides as a consequence. Similarly, the Norwegian Meråkerbanan was hit by a landslide a week after electrifying the Trondheim-Storlien section on November 7, 2025. 100 meters of the rails ended up in the river, and the repair was estimated to take about 5 months. This railway connection is one of two between Norway and Sweden north of the Dalälven.
Sweden's infrastructure has many critical points that are relatively easy to knock out, attractive targets in both conventional and hybrid conflict. The paradox is that Sweden is indispensable for the Nordic defense but at the same time its most vulnerable link. In order to be able to build new and repair existing infrastructure, a business community is needed that demands increased capacities, which can also cover the majority of the need for the defense of the Nordic region. In other words, measures that are economically "profitable" must be prioritized. This is not done by fulfilling the wishes of the one who screams the loudest, but by analyzing the overall need in the Nordic region from a helicopter perspective and what forms of financing different routes could receive. There are several different possible solutions depending on the importance, NATO contributions, EU part-financing, public-private cooperation or government investments. In addition, the Nordic repair readiness needs to be increased and coordinated between the countries to make the system less vulnerable.
The development of Nordic basic industries will depend on the development of infrastructure. These will combine two perspectives that will be significant for defense capability: economic growth will mean that the Nordic region will become more robust in financing a war chest. In addition, the industries are considered to be able to reduce non-European dependence on raw materials and energy, such as rare earth metals.
To understand the infrastructure, one must look at the clusters it serves, the population structure, which forms the basis of both the industrial and agricultural clusters which are linked together by a logistical network. Sweden's population and production are concentrated in a few economic regions where people, industries and transport overlap:
- The Stockholm/Uppsala region is the largest, with strengths in IT, fintech and life science, and is also the largest logistics node, with Stockholm North accounting for 14% of the country's warehouse capacity.
- Gothenburg/Västra Götaland is the center for the automotive industry, electrification and maritime activities, with the Port of Gothenburg as the Nordic region's most important and largest hub for civilian transport.
- The Malmö–Öresund region is characterized by research, life science and logistics connected to EU markets via the Öresund Bridge.
- A broader southern cluster includes Jönköping (12% of the warehouse space), Växjö, Kalmar and Karlskrona, important for manufacturing, agriculture and exports.
- Norrland is sparsely populated but economically crucial through mines, forests and energy surpluses, and perhaps in the future, the hub of the EU's new green industry.
- Bergslagen and central Sweden form the historic industrial belt from Karlstad in the west to Norrköping and Gävle in the east.
Together, these clusters form Sweden's national backbone, where demography, industry and logistics interact. Any major transport strategy that takes into account both business and society's demands for robustness and adaptation must effectively build all six areas together with great redundancy.
The Trans-European Transport Network (TEN-T) (for roads, rail, maritime transport and air), connects the Nordic countries to the continent by road through axes such as Copenhagen-Oslo via Gothenburg, Copenhagen-Stockholm via Jönköping, Oslo-Kotka via Stockholm-Helsinki, and Luleå-Narvik. The railway network largely reflects the same structure, but is still largely built on 1800th-century embankments. The railway network is therefore to be considered an older version of the same basic structures within national transport needs than the road network. In the larger outlines, less has changed, but in the details there is a lot that is different. Both networks have been hard-pressed by many heavy goods transports and the load-bearing capacity of the bridges has become the system's biggest bottleneck. This is related to both the business community's need for heavier transport by road, HCT (High Capacity Transports), and the requirements for capacity for military movements.
The Nordic region is now entering an era where transport infrastructure, not geography, defines security and defense capability. The systems that transport people, energy, goods and military forces are the limits to the operational capability and endurance of the military system. Every reinforced bridge, renovated railway and removed bottleneck increases the Nordic region's military resilience and operational capability.
NATO addresses 7 basic requirements for total defense in Article 3, infrastructure is number 7 of these, but is actually a prerequisite for most of the other 6 to be ensured. No one questions the fact that Nordic transport infrastructure needs extensive upgrading. The common strategy clearly demonstrates this. What remains is to resolve funding priorities nationally and between the Nordic countries, as there are contributions to be received from both the EU and NATO. What is required is to immediately put the shovel in the ground for the most prioritized projects and to demonstrate that an increased military capability is being built through an improved transport network in the Nordic countries, which also means increased deterrence towards Russia.
