An Industrial Power Under Pressure
For decades, Germany has been portrayed as Europe’s economic engine. Its industrial model, built on advanced manufacturing, low-cost energy and technological integration, supported high employment, solid public finances and a leading role in European institutions. That model is now experiencing structural stress. International geopolitical tensions, the war in Ukraine, the end of cheap Russian energy, slowing global growth and Asian competition are all pressuring the German productive system. Exports are under strain, domestic consumption is stagnating, and business and consumer confidence are declining. In this context, the decision to launch a vast rearmament program appears not only as a strategic security choice, but also as an instrument of economic policy designed to sustain employment and compensate for falling demand.
German rearmament cannot be interpreted merely as an emotional reaction to Russia’s invasion of Ukraine. It represents a long-term economic repositioning. The military industry provides secure orders, technological autonomy and stable public investment at a time when other strategic sectors — automotive, chemicals, and metallurgy — are losing competitiveness and profitability. The transformation currently underway is profound and marks a change of economic paradigm.
The End of the Old Growth Model
To understand Germany’s strategic shift, one must first examine how the old model worked. For more than twenty years, Germany built its prosperity on the ability to export high-quality products to global markets. Automobiles, industrial machinery, chemical products and engineering technologies guaranteed strong trade surpluses and a wide fiscal base. Export success allowed Germany to keep domestic consumption moderate, limit wage growth and invest relatively little in civilian infrastructure. Foreign demand compensated for internal weaknesses.
That model has now cracked, under the pressure of both external forces and internal contradictions. China, for years an ideal export market, is today a direct competitor in key sectors such as electric vehicles, electronics and battery production. The United States, once a major importer, has adopted protectionist industrial policies through the Inflation Reduction Act, which favors domestic manufacturing. Russia, long a decisive energy partner, has disappeared from Germany’s economic geography since 2022. Rising energy costs have hit particularly hard an industry that relies heavily on electricity.
The result is slower productivity, weakened international competitiveness, and an atmosphere of uncertainty affecting companies and workers alike. Germany has discovered just how fragile part of its prosperity was: it depended on cheap energy, stable markets and efficient global supply chains. Geopolitical crisis has challenged all of those assumptions.
Energy Shock: From Russian Gas Dependence to Price Volatility
For many years, Russian gas was the backbone of German industrial competitiveness. It was cheap, stable, abundant and seemed politically insulated. Gas powered the chemical industry, metallurgy, paper and glass production, and enabled the entire manufacturing system to maintain a cost advantage over international rivals.
The war in Ukraine abruptly ended this equilibrium. The energy shock had immediate consequences. Many companies scaled back production, some temporarily shut down, others considered relocating outside Europe. Energy bills tripled within months, and competitiveness dropped. The energy crisis affected not only industrial output, but also household budgets and domestic demand, with direct consequences for consumption and investment.
In this new context, Germany was forced to reconsider the very structure of its economy. The decision to invest massively in defense, presented by Chancellor Olaf Scholz as a “Zeitenwende”, an epochal turning point, cannot be understood solely as a political or military gesture. It coincides with the need to sustain domestic industry in an era of high energy costs and uncertain foreign demand.
The War in Ukraine, European Security and Rearmament
The war in Ukraine is the most significant geopolitical turning point for Germany since reunification. For the first time since World War II, national defense has returned to the center of political debate. The perceived threat to European security generated broad political consensus to increase military spending. Parliament approved a special €100-billion fund for the modernization of the armed forces.
This decision was justified on national security and solidarity with Ukraine, but its economic implications are substantial. The military industry receives large orders that translate into stable employment, technological development and investment across wide industrial supply chains. Major defense companies such as Rheinmetall, Krauss-Maffei Wegmann and Thyssenkrupp Marine Systems saw their market valuation rise and announced expansion plans.
German rearmament is thus the outcome of a new convergence between geopolitical necessity and economic needs. The perceived threat from Russia helped legitimize major public intervention in the real economy. Germany has discovered that defense, after decades of marginality, can become an industrial pillar.
Rearmament as Industrial Policy
German rearmament functions as a full-scale industrial policy. The production of weaponry involves numerous technological sectors: mechanical engineering, electronics, robotics, composite materials, military software and cyber security. Public and private investments generate spillovers across the value chain. State procurement creates productive continuity and stability, qualities especially valuable in a moment of global market uncertainty.
Germany is building a new industrial platform. What had long been the locomotive of European manufacturing — the automotive sector — is under pressure. Chinese competition in electric vehicles has reshaped global balances. The chemical industry suffers from energy costs and increasingly strict environmental regulation. Steel and glass production are losing margin. Defense, by contrast, appears to be a sector with growing demand, higher margins and less aggressive international competition. These are not products sold on open markets, but sovereign contracts guided by political priorities.
Rearmament therefore acts as a buffer against recession. When private demand declines, the state can intervene as buyer of last resort. Once approved, military spending rarely faces cyclical restrictions: national security concerns tend to reduce parliamentary resistance. This guarantees stability and continuity to the companies involved.
Employment and Social Cohesion
Germany fears unemployment as much as recession. Its political stability depends on a strong labor market. For years, exports guaranteed employment. With that model in crisis, job losses have become a real risk. Rearmament offers a solution. Companies hire engineers, technicians, skilled workers, programmers, maintenance personnel and logistics specialists. Defense supply chains can be regionalized, supporting industrial regions and local budgets.
This has important implications for social cohesion. Germany retains a historical memory of mass unemployment. The joblessness of the 1930s remains a vivid warning in political culture. No one wishes to repeat a spiral of mistrust, poverty and radicalization. Rearmament, ethically controversial as it may be, is perceived as a guarantee of economic stability.
The European Dimension and International Role
German rearmament does not occur in isolation. Debate on European defense intensified after 2022. The European Union discovered its strategic vulnerability. It depends on the United States for military protection, on China for technology, and on external suppliers for energy. In this context, Germany sees opportunity. If Europe must spend more on defense, someone must produce the weapons. Berlin aims to lead that production.
Cooperation with Eastern European states has increased. Poland, the Czech Republic and the Baltic states feel threatened by Russia and intend to strengthen their armed forces. Germany has positioned itself as a natural supplier of advanced defense systems. The European defense market, still fragmented, could consolidate around German technological standards. Industrial leadership would convert into political influence.
Internationally, Germany must balance two priorities: maintaining ties with the United States while developing greater European strategic autonomy. The war in Ukraine has strengthened the Atlantic Alliance, but has also shown that Washington’s priorities stretch beyond Europe. The United States is focused on the Pacific and China as its main challenge. Berlin understands that Europe cannot depend entirely on American support. German rearmament is therefore also a political insurance policy.
Risks, Limits and Consequences
Every strategic decision has costs. Expansion of the military industry can generate dependencies and distortions. If the economy becomes too reliant on armaments, the country may grow sensitive to continued geopolitical tension. History shows that militarized economies tend to justify spending through narratives of external threat. Competition among defense firms and pressure on governments can influence political choices.
Another risk concerns fiscal sustainability. Although the €100-billion special fund was created outside normal budget rules, Germany remains committed to fiscal discipline. If military expenses continue to rise over time, they could conflict with other priorities such as healthcare, education and welfare. German society will need to find a balance among competing demands.
At the international level, German rearmament may provoke concern. Some European countries retain uneasy memories of Germany’s military past. German public opinion, traditionally pacifist, is undergoing a complex cultural transition. The war in Ukraine has changed perceptions of threat, but has not erased decades of historical memory.
Conclusion: A New Phase in German History
Germany is undergoing a profound transformation. The crisis of its economic model, the war in Ukraine, the energy shock and global competition have made clear the need to reinvent the productive system. Rearmament is now a response that unites security and industrial policy. It provides employment, investment, technological prospects and a narrative of protection in uncertain times.
This choice has geopolitical and moral consequences. Germany, historically a peaceful industrial power, is becoming a military pillar of Europe. Its future will depend on the ability to reconcile security with responsibility, economic development with international cooperation, strategic autonomy with Western alliances.
The crisis has opened a new era. The old engine based on Russian energy and global exports is gone. The new engine produces weaponry, dual-use technologies and defense systems. Germany is becoming a key actor on a continent that has rediscovered the harshness of geopolitics. Rearmament appears to be the most realistic response to a historical phase marked by uncertainty. Only time will tell whether this choice — born of economic necessity and international pressure — will ensure long-term stability and prosperity.
