NATO Annual Report 2025: A Historic Turning Point in European Defense Policy

The NATO Annual Report 2025, published on March 26, 2026, marks a decisive turning point in the transatlantic security architecture. NATO Secretary General Mark Rutte presented figures that impressively demonstrate the extent of the transformation: European allies and Canada increased their defense spending in 2025 by a real 20 percent compared to the previous year – already the second consecutive year with such a growth rate. Even more remarkable is the fact that, for the first time in the history of the alliance, all 32 member states have achieved the two percent target.

This development is the result of several years of pressure, originating from the changed geopolitical situation following Russia's invasion of Ukraine in February 2022. While then-German Chancellor Angela Merkel described the two percent target as "guiding" at the NATO summit in Wales in 2014, it remained a non-binding recommendation for many European states for years. Only the combination of repeated demands from the Trump administration and the concrete threat on NATO's eastern flank led to this fundamental rethinking.

The financial dimension of this transformation is significant. In 2021, only 30 percent of European NATO members and Canada met the two percent target, but we are now talking about full compliance. In absolute terms, the 20 percent increase translates to an increase of several dozen billion euros in 2025. Germany, for example, raised its defense budget from around 52 billion euros in 2024 to an estimated 85 billion euros in 2025 – a leap that would have been politically unthinkable just a few years ago.

However, Rutte warned against resting on this success. In his presentation of the report, he emphasized that the alliance must already move towards a new, significantly more ambitious goal: five percent of gross domestic product by 2035. This demand reflects the assessment of leading NATO strategists that the current threat situation requires a fundamental realignment of European defense capabilities. Particularly in the context of the emerging strategic realignment of the United States, which aims to concentrate its military resources more on the Indo-Pacific region, this perspective gains urgency.

Pentagon representatives have already made clear in this context: by 2035, European allies should be able to take on the majority of the responsibility for continental defense. This timeline illustrates that the current increases in spending are just the beginning of a long-term transformation process. The challenge lies not only in providing financial resources but, above all, in building actual military capabilities.

Here, one of the central weaknesses of European defense policy is revealed: industrial capacity. While budgets are increasing, the European defense industry is lagging significantly in the production of critical weapon systems. For example, ammunition production has not been able to increase at the required pace despite significant investments. Artillery shells of caliber 155mm, which are needed in large quantities for support in Ukraine, cannot currently be produced in sufficient numbers by European manufacturers to replenish their own stocks and supply Ukraine.

Similar bottlenecks are evident in air defense systems, armored vehicles, and advanced weapon systems. The industrial mobilization that was gradually scaled back after World War II cannot be reactivated within a few months. Production lines must be rebuilt, skilled workers trained, and supply chains secured – a process that takes years and requires significant investments.

The political implications of this development are far-reaching. Within the European Union, there is increasing pressure to coordinate national arms procurement more closely and prioritize joint European projects. Initiatives such as the Future Combat Air System (FCAS), a German-French-Spanish cooperation to develop a next-generation combat aircraft, or the Main Ground Combat System (MGCS), a successor project for the Leopard 2 tank, gain strategic significance in this context. At the same time, they reveal the inherent difficulties of European defense cooperation: differing industrial interests, divergent operational requirements, and national sovereignty concerns complicate swift realization.

Another critical aspect is the question of strategic autonomy. While European states are expanding their defense capabilities, dependence on American technology in key areas remains. Satellite communication, reconnaissance capabilities, and advanced weapon systems still heavily rely on U.S. components and know-how. Building genuine European capabilities in these areas would require not only significant financial investments but also long-term political coherence, which is difficult to achieve in the fragmented European security landscape.

The increase in spending praised in Rutte's report is undoubtedly a significant step. It shows that European governments have recognized the seriousness of the situation and are willing to mobilize substantial resources. Nevertheless, the question remains whether this momentum is sustainable. The economic situation in many European states is strained, with stagnant growth and high debt. Defense spending competes directly with social benefits, infrastructure investments, and climate protection measures – politically sensitive areas where every euro is contested.

In the long term, the success of this defense transformation will depend on whether a societal consensus can be achieved regarding the necessity of substantial defense investments. Public opinion in many European states is divided, and political support for massive rearmament is fragile. Here, the communicative task of political leaders will be crucial: to clearly articulate the threat situation without inciting panic and to convey the necessity of credible defense capabilities without giving the impression that preparations are being made for an inevitable conflict.

The NATO Annual Report 2025 documents a historic turning point. After decades of neglect, Europe is once again investing substantially in its defense. However, the true test lies ahead: turning money into military capabilities, building industrial capacities, and maintaining political will. The coming years will show whether 2025 will indeed go down in history as the beginning of a new era of European defense policy – or whether it will remain a brief flicker of determination.
