Europe's Defense Shift: NATO Members Achieve 2% Target for the First Time – and Are Already Discussing 5%

The NATO has announced a historic milestone in its annual report for 2025: For the first time since the introduction of the target benchmark, all 32 member states have reached the agreed minimum requirement of 2% of gross domestic product for defense spending. NATO Secretary General Mark Rutte described 2025 in his presentation on March 26, 2026, as a "turning point" and already announced that the alliance must aim for significantly more ambitious goals in the medium term – specifically, he mentioned 5% of GDP by 2035.

The figures in the report demonstrate a dramatic acceleration of European rearmament: European NATO partners and Canada increased their defense spending in 2025 by 20% in real terms compared to the previous year – marking the second consecutive year with this rate of increase. In absolute numbers, this means an increase from $1.3 trillion to over $1.4 trillion for the entire alliance. For Europe and Canada alone, this increase corresponds to several tens of billions of dollars in additional funds flowing into arms procurement, infrastructure, and personnel growth.

Particularly noteworthy is the development on NATO's eastern flank. Poland, Lithuania, and Latvia have already exceeded the new target of 3.5% of GDP in 2025, according to estimates in the report – a level that is only being discussed as a medium-term goal for the rest of the alliance. These three states, which have a particularly pronounced perception of threat from Russia due to their geographical location and historical experiences, are thus driving the debate on a redefinition of NATO defense standards.

The strategic implications of this development are multifaceted. On one hand, the European allies are fulfilling long-standing American demands – particularly the vehement criticism of former President Donald Trump during his first term regarding the lack of burden-sharing. Rutte explicitly praised Trump's pressure in his speech as an important catalyst for the trend reversal now achieved, after years of warnings from previous U.S. administrations had shown only limited success. This diplomatic reference is likely also politically motivated: Acknowledging American demands is intended to strengthen transatlantic solidarity and signal to Washington that Europe is ready to take on more responsibility.

On the other hand, the new 5% discussion raises fundamental questions about military strategy and industrial policy. An increase from the current average of 2% to 5% of GDP would mean an unprecedented resource shift for the large European economies. Germany, for example, would have to more than double its defense spending from around 80 billion euros to over 200 billion euros. France, which already has a comparatively capable defense industry, would need to ramp up from about 60 billion to 150 billion euros.

Rutte explicitly links the demand for higher spending to the necessity of massively expanding European arms production. The experiences from supporting Ukraine have ruthlessly revealed that Europe is unable to produce ammunition, spare parts, and weapon systems in the required quantities and with the necessary speed. While the U.S. was able to scale up its industrial base relatively quickly, European manufacturers struggle with fragmented national markets, lengthy procurement processes, and a lack of economies of scale.

However, the economic conditions for this rearmament wave are challenging. Many NATO states are experiencing stagnant economic growth. In this environment, significantly higher defense spending inevitably means cuts in other areas – whether in social benefits, education, or infrastructure – or an increase in national debt. The political feasibility of doubling or even tripling military spending is therefore questionable in many democracies, especially when public opinion is divided on how to deal with Russia and the role of NATO.

Nevertheless, the speed with which all 32 members have reached the 2% target shows a fundamental shift in security policy priorities. Just a few years ago, the 2% target was considered politically nearly unattainable; skeptics pointed out that many states had been significantly below that for decades. However, Russian aggression against Ukraine, combined with Chinese power ambitions in the Indo-Pacific and the increasingly unpredictable U.S. foreign policy under changing administrations, has created a security awareness that establishes new realities.

The question now is whether Europe can make the leap from a quantitative increase in spending to a qualitative transformation of its defense capabilities. Higher budgets alone do not guarantee more effective deterrence or better military readiness. It will be crucial whether the additional funds are invested in strategically meaningful capabilities – such as air defense, precision munitions, cyber defense, and maritime surveillance – and whether it is possible to consolidate and modernize the European defense industry.

NATO is thus facing a historic transformation process. After decades of relative underinvestment and strategic ambiguity, Europe is undergoing a shift whose extent and consequences are not yet foreseeable. The fact that a NATO Secretary General is publicly discussing a 5% target for 2035 would have been unthinkable just a few years ago. Today, it is a reflection of a new geopolitical reality in which military strength is once again regarded as an indispensable prerequisite for security and political influence.
