European defense: who's really paying?
Europe's rearmament is accelerating — but the spending map reveals deep fault lines that The Hague commitments alone won't be enough to close.
At a Glance
For the first time since NATO’s 2014 Wales Summit formalized the 2%-of-GDP commitment, every member of the alliance hit that target simultaneously in 2025 — a threshold that was already obsolete by the time it was reached.
Geography dictates conviction: Poland, Lithuania, Latvia, and Estonia lead European defense investment, all sharing land or sea borders with Russia.
Spain, Belgium, and Italy have increased their budgets, but remain at the bottom of the rankings — and the road to the 3.5% target agreed at The Hague in June 2025 will be long.
The 2% threshold: a statistical win, not a strategic one
In 2025, for the first time since NATO’s 2014 Defence Investment Pledge established a formal 2%-of-GDP commitment, every member of the alliance met that target — compared to just 10 countries that had honored the commitment in 2023. NATO Secretary General Mark Rutte hailed the milestone. The press releases followed.
But the arithmetic consensus masks a more fragmented reality. European defense investment rose 14% in 2025, reaching €739 billion — the sharpest increase since the 1950s, and double what the continent was spending a decade ago. That is undeniable. What is less clear is that the 2% bar — now universally cleared — was already outdated the moment it was finally crossed.
For an American or Canadian reader, the analogy is direct: imagine Congress finally passing the defense budget it had been promising for twenty years, at the exact moment the Pentagon announced it needed three times as much. Political timelines and strategic realities rarely run on the same clock.
Geography as a budget compass
There is no mystery in the numbers. Poland devotes 4.3% of its GDP to defense — surpassing even Washington at 3.19%. Lithuania stands at 4%, Latvia at 3.74%, Estonia at 3.42%, Finland at 2.87%. These five countries share one thing: a land or maritime border with Russia or Belarus.
On average, moving 600 miles closer to Moscow pushes defense spending up by 0.6 percentage points of GDP. Perceived threat gets priced in concrete, artillery rounds, and troop deployments — not in summit declarations.
At the other end of the spectrum, Portugal, Belgium, and Spain spend barely 2% of GDP on defense — the bare formal minimum, reached in some cases through accounting logic that could include expanded definitions of eligible expenditures — cybersecurity, dual-use infrastructure — whose exact perimeters vary from one country to the next.
Germany shifts weight — Spain still holds back
Berlin invested approximately €97 billion in defense in 2025, a 24% jump from the previous year, overtaking the United Kingdom to become Europe’s top defense spender in absolute terms and the fourth-largest in the world. For a country long constrained by its own history to a posture of strategic restraint, the shift is structural, not cyclical.
Italy and Spain also increased their budgets — though less convincingly. Spain, a habitual NATO underperformer, surged 50%, bringing its defense spending to 2% of GDP for the first time since the early 1990s. A 50% increase just to reach the minimum floor: the scale of the jump says something about the decade of disinvestment that preceded it.
At The Hague summit, European nations — with the notable exception of Spain — signaled their readiness to push defense spending toward 5% of GDP. Madrid declined to sign the collective commitment, a political signal that the Sánchez government has struggled to frame as anything other than a divergence in priorities.
Readiness 2030: the institutional architecture, without the orders
On March 4, 2025, the European Commission — the EU’s executive arm — unveiled ReArm Europe, later rebranded as Readiness 2030 after criticism that the original name struck too martial a tone. The plan aims to mobilize up to €800 billion in defense investment by 2030. On May 27, the EU Council adopted SAFE (Security Action for Europe), a €150 billion loan facility conditioned on joint procurement and a minimum of 65% European-sourced components.
On paper, the architecture is coherent. In practice, the conversion into actual industrial orders remains slow. Only 10 of the EU’s 27 member states have committed to spending at least 3% of GDP on defense by 2030. Defense manufacturers feel the gap in real time: order books have not yet absorbed the ambition of the speeches.
EU member states currently operate 98 different major weapons systems, compared to just 18 for the United States. That fragmentation is the symptom of a decade of stacked national industrial sovereignties — and one of the structural obstacles that Readiness 2030 claims to address, without a binding timetable to do so.
Analysis — What the numbers don’t say
① The 2% rule was a political metric, not a strategic one. The fact that it was universally reached in 2025 signals, above all, that the benchmark itself had expired. NATO tacitly acknowledged this by setting a new target of 5% by 2035 — with 3.5% earmarked for core defense and 1.5% for infrastructure resilience. This shift in the goalposts could indicate that the Atlantic alliance has resolved to operate in a fundamentally different budget category, even if the translation of commitments into real capabilities remains to be demonstrated.
② Geography no longer explains the gaps alone. Proximity to Moscow correlates with budgets but does not determine the ability to project force. Poland spends 4.3% of GDP on defense — but a significant share of that equipment may be sourced from the United States and South Korea, which could limit the knock-on effect for Europe’s own defense industrial base. The SAFE loan instrument, conditioned on local content requirements, is explicitly designed to redirect that dependency.
③ The fracture is not only financial. Spain’s refusal to endorse the 5% commitment, and Rome’s and Madrid’s criticism of Readiness 2030 as too narrowly focused on military hardware, could signal a deeper divergence over what European defense is actually supposed to achieve — whether it is a response to an immediate Russian threat, or a broader investment in systemic resilience encompassing cybersecurity and critical infrastructure. That tension remains unresolved, and it will ultimately determine whether the collective effort produces coherent operational capability or a patchwork of uncoordinated national ambitions.
The Bottom Line
Every ally has cleared the 2% mark. The next target is 5%. In between lies a decade — and a question European summits have not yet resolved:
Who decides, on this continent, what to protect and how — and how to turn a collection of national budgets into a credible collective capability against a threat that is not waiting for committee reports?
