Europe's Defense Shift: The 5 Percent Goal and the Realignment of NATO Strategy

The European defense policy is currently undergoing what is arguably the most profound transformation since the end of the Cold War. At the center of this upheaval is an ambitious new spending target: by 2035, NATO member states are to allocate five percent of their gross domestic product to defense and security. This target, agreed upon at the NATO summit in The Hague last year under significant pressure from the Trump administration, marks a paradigm shift that has substantial budgetary, strategic, and industrial policy dimensions.

The new formula divides spending into two components: 3.5 percent of GDP is to be allocated to traditional military core expenditures—personnel, operations, equipment, and maintenance. The remaining 1.5 percent is earmarked for security-related areas, including cyber defense, supply chain resilience, critical infrastructure, logistics, and defense innovation. This structuring reflects the changed nature of modern threats, which are no longer limited to conventional military capabilities but include hybrid dimensions.

Germany has positioned itself as a driving force in this development. After years of restraint and chronic underfunding of the Bundeswehr, the German defense budget surpassed the symbolic threshold of 100 billion US dollars for the first time in 2025, reaching 107 billion dollars—a rise of over 24 percent compared to the previous year. This massive influx of funds is accompanied by fundamental reforms in procurement processes. On February 13, 2026, the revised Bundeswehr Procurement Acceleration Act (BwBBG) came into force, aimed at streamlining the notoriously sluggish procurement procedures and strengthening supply security as well as European sovereignty in arms production.

The federal government is now managing a consolidated procurement portfolio of approximately 377 billion euros across around 320 programs. By the end of 2026 alone, contracts worth an estimated 83 billion euros are to be signed. Recent examples underscore the new dynamics: the Budget Committee of the Bundestag approved two framework contracts at the end of February with a total volume of 4.3 billion euros for the procurement of the HX-2 system and the Virtus combat drone. In parallel, Berlin concluded two framework contracts of 270 million euros each for defense drones with the companies Helsing and Stark Defense—an indication of the growing importance of unmanned systems and autonomous weapon platforms.

France is pursuing a similarly ambitious line. For the year 2026, Paris has targeted military procurement contracts worth 42 billion euros. This figure signals the ambition to belong not only quantitatively but also qualitatively to the leading military actors—not just on paper, but in concrete tonnage of steel, flight hours, and satellite coverage, as one analyst put it. Both countries, Germany and France, together bear the lion's share of European defense spending, thus forming the backbone of a changing European security architecture.

However, the transformation is by no means proceeding smoothly. The most prominent example of the difficulties of cross-border arms cooperation is the Future Combat Air System (FCAS), the Franco-German prestige project for the development of a next-generation combat aircraft. Reports suggest that the program is in serious trouble and may be on the verge of failure. A potential German withdrawal from FCAS would not only jeopardize a single project but also raise fundamental questions about the future of bilateral defense cooperation between the two largest European defense spenders.

Experts from the International Institute for Strategic Studies (IISS) argue, however, that the European defense industry as a whole is resilient enough to withstand such setbacks. Increasingly, EU member states are relying on smaller, more pragmatic coalitions that focus on common operational requirements and concrete procurement projects. The German European Sky Shield Initiative (ESSI) is a prime example of this—a air defense network that integrates sensors, interception systems, and tactical control systems. Similarly, the Common Armored Vehicle Program involves seven countries jointly procuring armored vehicles on a larger scale.

These "coalitions of the willing" could prove to be a more pragmatic and effective alternative to the previous, often stalled bilateral large projects. They allow participants to respond flexibly to specific threats and leverage economies of scale without getting bogged down in the bureaucratic pitfalls that characterize traditional large projects like FCAS.

Not all NATO members are following the new line unreservedly. Spain has explicitly rejected the 5 percent target. Prime Minister Pedro Sánchez argued in Munich that his country could meet NATO capability goals with lower spending. This stance reflects a broader debate: Is it ultimately about absolute spending levels or about concrete military capabilities? Critics of the percentage-based approach warn that a purely budget-oriented target could lead to inefficient spending, while proponents emphasize that the decades-long underfunding of European armed forces can only be remedied through massive, sustainable investments.

In parallel to national efforts, the European Union is intensifying its own defense initiatives. A recently approved support package for Ukraine amounting to 90 billion euros for the years 2026 and 2027 underscores the new prioritization: 60 billion euros of this—two-thirds—are earmarked for military purposes. These figures highlight that the EU is not only acting as a normative actor but increasingly as a security policy player.

Another notable signal is the increased transatlantic coordination despite political tensions. Elbridge Colby, a senior official at the Pentagon, recently expressed a positive view of the idea that Europe could allocate a larger share of its defense spending through EU channels. Under the slogan "NATO 3.0," he outlined a vision in which Europe takes primary responsibility for its conventional defense, supported by American nuclear deterrence and strategic capabilities. This realignment could make the transatlantic relationship more sustainable by distributing the burden more equitably while simultaneously strengthening Washington's ability to focus on the Pacific region and the challenge posed by China.

Recent NATO exercises underscore the operational dimension of this transformation. On February 11, 2026, the new exercise "Arctic Sentry" was launched, the latest in a series of maneuvers aimed at testing alliance readiness and improving interoperability among the armed forces. Such exercises serve not only military preparation but also as a political signal of unity and determination.

However, the challenges remain immense. Europe faces the task of closing capability gaps that have arisen from decades of systematic underinvestment within a few years. The European defense industry must significantly expand its production capacities—a task that requires not only capital but also time, skilled labor, and strategic planning. Additionally, national egoisms and industrial policy particular interests must be overcome to achieve efficient, complementary division of labor.

The coming years will be crucial. Whether Europe can actually achieve the strategic autonomy it has long rhetorically invoked will be measured by whether the budgets now announced can indeed be translated into operational capabilities. The 5 percent target is less an end in itself than a measure of political will to fundamentally modernize the continent's security architecture. The transformation is underway—its completion remains an open question.
