BREAKDOWN: 5% OF GDP FOR NATO BY 2035 — WHAT IT REALLY MEANS

Introduction: The figure that rewrites the history of Western defense

An explosive figure adopted in relative silence

In June 2025, at the The Hague summit, NATO's 32 members made an unprecedented commitment since the Alliance's founding: to reach 5% of gross domestic product in defense and related spending by 2035. The target is structured in two layers: at least 3.5% of GDP for core defense needs, and the remainder for related spending — cybersecurity, critical infrastructure, innovation, resilience. Ten years. Five percent. These two figures resemble nothing the Western democracies have known since the end of the Cold War. For many allies, reaching them would require doubling or tripling their current budgets. This breakdown dissects the mechanism, measures the gaps, and evaluates the chances it actually happens.

The pre-ministerial press conference of June 17, 2026 confirmed that European allies and Canada had increased defense spending by more than $90 billion in 2025 — nearly 20% growth in a single year, according to Mark Rutte. That is a remarkable figure. But it is insufficient to reach 5%. The gap between the recorded increase and the final target is considerable. And measuring that gap precisely means understanding what NATO can realistically accomplish before 2035.

Why 5% and not 3% or 4%?

The 5% figure did not fall from the sky. It is the product of an analysis of what Europe's defense would require in several simultaneous scenarios. Secretary of War Pete Hegseth had expressed this logic in his speech of June 18, 2026 on war.gov: allies must be able to defend Europe even in the event of simultaneous conflicts in other regions of the world. This scenario — Russia attacking in Europe while China acts in the Pacific — requires forces that current budgets cannot generate. NATO, under this logic, must stop depending on total availability of American forces.

The arithmetic is brutal. If the United States must mobilize major forces against China in the Pacific, its capabilities available for Europe would drastically shrink. Europe would then have to hold its front with its own forces. From what critical mass of spending is that possible? Military planners put a figure on it: 3.5% of GDP in strict defense, with an additional 1.5% for support infrastructure. Together, that is 5%. This is not a political projection. It is a calculated military requirement.

The target structure: 3.5% + 1.5% = 5%

The defense core: what the 3.5% covers

The 3.5% of GDP dedicated to core defense needs funds the classic elements of military power: personnel, equipment, munitions, training, military infrastructure, defense research and development. This is the hard core of the commitment. According to the framework adopted at the 2025 The Hague summit, as analyzed by Simon Gros on simongros.org on June 21, 2026, this 3.5% is presented as "the minimum acceptable target" for the United States in evaluating allies. Below that, American planners consider the ally does not contribute sufficiently to collective defense.

For comparison, in 2024, only two NATO members — Poland and the United States — exceeded or approached 3.5% of their GDP. Poland was spending approximately 4%. Most European allies were between 1.5% and 2.5%. To go from there to 3.5% by 2035, budgets must on average increase by 50 to 150% depending on the country. This is achievable over ten years. But it requires sustained political will across three or four electoral cycles. And this is precisely where the highest risk of failure lies.

The complementary 1.5%: innovation, cyber, infrastructure

The additional 1.5% — bringing the total to 5% — covers related defense and security spending: cybersecurity, critical resilience infrastructure (bridges, ports, tunnels capable of supporting heavy military traffic), defense innovation, supply chain security. This category is both more flexible in its definition and more contestable in its accounting. Some allies may be tempted to reclassify existing civilian spending as related defense spending to meet the target on paper without actually increasing their military capabilities.

This risk of creative accounting was anticipated. The American posture review announced by Hegseth on June 18, 2026 seeks precisely to distinguish real increases from cosmetic reclassifications. The requirement is not only budgetary — it is also qualitative. A country spending 5% of its GDP renovating road bridges and funding tech startups with no direct military link will not satisfy American requirements, even if the accounting is formally correct. Substance takes precedence over form. That is the whole difference.

The 2025 sprint: 90 additional billion in one year

A historic leap, but not sufficient

Rutte's press conference data from June 17, 2026 is striking: European allies and Canada spent $90 billion more on defense in 2025 compared to 2024. A 20% increase in a single year. To put this in perspective: it is the equivalent of the combined annual defense budget of Italy and the Netherlands. It is the largest spending increase in Europe in peacetime since the Cold War. And it is directly attributable to American pressure and the dissuasive effects of the Russian invasion of Ukraine in 2022.

But let us relate this figure to the target. If European allies were spending on average approximately $550 billion per year on defense in 2024 — aggregate estimate — an increase of $90 billion brings them to approximately $640 billion. To collectively reach 5% of GDP, the required amount would be on the order of $1,400 to $1,600 billion per year — based on European and Canadian GDP size. There remains a gap of several hundred billion to bridge. This is not impossible. But it is not guaranteed.

The increases inscribed for 2026

Rutte specified at his press conference of June 17, 2026 that "new increases were already inscribed for 2026." Without giving a global figure for 2026 — the data were not yet available — he signaled a continuation of the trend. Several countries had announced significant increases: Germany voted a record defense budget, France accelerated its military programming law, Poland maintains its trajectory toward 4%. The Nordic countries — which all recently joined or are close to joining NATO — have spectacularly increased their spending following the Russian invasion.

If the 2025 trend is maintained at a similar pace in 2026, Europe will have accumulated in two years an increase in defense spending on the order of $180 to $200 billion. This is a real transformation. But the trajectory to reach 5% by 2035 requires this rate of increase to be maintained for several more years — which depends on political, economic and geostrategic factors impossible to predict with certainty. The war in Ukraine, American pressure, and rising Chinese threats are catalysts. Their permanence is not guaranteed.

Country by country: who is on track, who is not

The top performers already above 3%

In spring 2026, several NATO allies had already exceeded or approached 3% of GDP in defense spending. Poland leads the pack at approximately 4% — driven by its border with Russia via the Kaliningrad enclave and its border with Belarus. The Baltic states — Estonia, Latvia, Lithuania — are all above 3% and have announced trajectories toward 5%. Finland, which joined NATO in 2023, has significantly increased its spending. Norway and Denmark have also accelerated their defense investments. These countries have one thing in common: a border or direct proximity with Russia that transforms abstract risk into concrete threat.

The United Kingdom, despite its post-Brexit budgetary difficulties, remains one of NATO's most capable forces and is committed to increasing its spending. The aid package of £752 million announced on June 18, 2026 — including 150,000 drones, more than 350 air defense missiles and radars — illustrates its capacity to mobilize resources. Britain is not at 5% of GDP. But it demonstrates political will and industrial capacity that goes beyond the sole budget measure.

The laggards: who must make the biggest effort

The situation is more complex for allies in southern Europe and some historic Alliance members. Italy, despite repeated commitments, historically sits below 2% of GDP. Spain likewise. Belgium was long cited as an example not to follow, with less than 1.5% for years. For these countries, reaching 5% by 2035 would represent a tripling or more of their current defense spending. In the context of their post-COVID fiscal constraints and high public debt, this is a considerable challenge.

Germany deserves a separate mention. With a GDP of more than 4,000 billion euros, even a small percentage represents colossal sums. Its vote for the 100 billion euro Sondervermögen in 2024 represented a historic break with its culture of defense austerity. But to reach 5% of its GDP, it would need to spend annually more than 200 billion euros — more than double its current defense budget. This would require either a constitutional reform of its debt brake, or a radical transformation of its national budget priorities.

The conversion mechanics: money is not enough

From budget to battalion: the conversion problem

Rutte's formula from June 18, 2026 deserves to be etched on the marble of every European defense ministry: "Money is crucial, but you can't stop a missile or a tank with a dollar or a euro." Converting budgets into real military capabilities is the central — and often neglected — challenge of the rearmament process. A doubled defense budget that funds unsuitable equipment, slow acquisition processes, poorly trained forces or inadequate logistics infrastructure does not produce military power proportional to the investment.

Conversion problems are multiple. First, industrial capacity: European defense industries were systematically reduced during thirty years of post-Cold War austerity. They cannot double production in one year. Germany and France have solid industrial bases, but order delays for complex systems like tanks, combat aircraft or air defense systems are measured in years. Second, qualified personnel: training soldiers, technicians and officers takes time. An increased budget does not immediately translate into deployable forces.

Defense acquisition cycles: the bottleneck

The European defense acquisition cycle is an institutional scandal of slowness. Systems whose need is identified in 2024 may not be delivered before 2032 if standard processes of tender calls, evaluations, contract negotiations, testing and serial delivery are followed. Ukraine, meanwhile, has shown that a nation at war can iterate a drone in three to four weeks — against a year or more for defense ministries of NATO countries. This gap between battlefield speed and bureaucratic acquisition slowness is a major strategic risk.

This is why the Ankara summit must address not only spending figures, but also the transformation of acquisition processes. Rutte expressed this at the June 18 meeting: we need steel, fire and contracts — not generic promises. Signed contracts, placed orders, committed delivery timelines — these are the real measures of political will on defense. Allies arriving at Ankara with concrete orders will have more credibility than those bringing only intentions expressed in percentages.

The 2035 scenario: is it realistic?

The conditions to reach the target

Is reaching 5% of GDP for all NATO members by 2035 realistic? The honest answer is: yes for some, no for others, and conditional for the majority. The conditions for success are known. First, a persistent threat: as long as Russia threatens Europe and China destabilizes the Indo-Pacific, political support for defense spending will remain high. If these threats diminish — for example, if a peace agreement in Ukraine seems durable — the temptation of a peace dividend will return. History shows this: democracies disarm quickly after conflicts.

Second, sufficient economic growth: 5% of GDP is easier to reach with a growing GDP. A prolonged recession or eurozone crisis would reduce defense budget financing capacity, even with strong political will. Third, internal political cohesion: in several NATO countries, anti-Atlanticist political parties are advancing. If these parties come to power, spending commitments could be revised. The trajectory of countries like Hungary or some central European nations illustrates this risk.

The two-speed scenario

The most likely scenario by 2035 is that of a two-speed NATO. A group of 15 to 20 allies — essentially Northern and Eastern Europe, plus the United Kingdom and, under pressure, Germany and France — will reach or approach 5%. Another group — mainly southern Europe — will remain significantly below. This scenario corresponds to what Hegseth's posture review is designed to identify. And it would transform NATO into an alliance with differentiated engagement levels.

This is not necessarily the catastrophe some fear. A two-speed NATO would be more honest about each member's real contributions. It would allow serious allies to plan Europe's defense relying on verified capabilities, without being held back by underperforming members. And it would send a clear signal to laggards: the entry ticket to the Alliance's hard core has a price, and that price is expressed as a percentage of GDP. This is not a beautiful solution. But it may be the only viable solution in an Alliance of 32 members with divergent interests and capabilities.

The impact on European defense industries

The industrial base: a reconstruction project

Reaching 5% of GDP in defense spending requires not only budgets, but also an industry capable of absorbing those budgets. The European defense industrial base was systematically reduced since the 1990s. Arms factories were closed, production chains shortened, expertise lost. Rebuilding this base takes time — and this is precisely what the Ankara summit must address in terms of strengthening the transatlantic industrial base, according to the priorities Rutte defined on June 18, 2026.

Encouraging signs exist. Germany signed in April 2026 an agreement with Ukraine for large-scale joint production of autonomous drones from German production lines. In February 2026, France, Germany, Italy, Poland and the United Kingdom had launched the LEAP project (Low-Cost Effectors and Autonomous Platforms) — joint production of low-cost air defense systems and autonomous drones integrating Ukrainian expertise. These initiatives show that the industrial base can evolve, if the political will is there.

The Chinese supply chain problem

One of the least discussed obstacles to the European defense industrial buildup is dependency on Chinese inputs. Modern weapons systems require rare earths, permanent magnets, electronic components — much of which is produced in China or processed by Chinese companies. China controls more than 90% of global rare earth production according to an ECFR report of June 2026. For a radar, a missile guidance component or a propulsion system, certain critical materials pass through supply chains that Beijing can cut.

The G7 meeting at Évian in June 2026, according to the South China Morning Post of June 22, 2026, adopted a declaration aimed at reducing below 60% the dependency on a "single non-G7 supplier" for rare earths and permanent magnets by 2030, with a target of 50% as soon as possible. This is a first step. But rebuilding alternative supply chains — in Canada, Australia, Africa — takes years and massive investments. The goal of 5% of GDP on defense will be easier to reach if Europe is not simultaneously forced to fight with suppliers who sell it the materials it needs to defend itself against their strategic allies.

Canada's role: an often-forgotten ally

Canada in the 5% equation

Canada is regularly cited as one of the most behind allies on defense spending commitments. Its historic contribution to NATO has been well below 2%, and the question of its rearmament has been a recurring friction point with Washington. But in 2026, things are moving. Prime Minister Mark Carney announced a commitment toward 5% of GDP by 2035, which would represent approximately $150 billion Canadian per year in defense spending — far more than currently.

Canada has also taken concrete decisions in 2026: it is sending warships to the Indo-Pacific, it is sanctioning 162 entities linked to the Russian shadow fleet, it is developing industrial cooperation with Ukraine, and it is negotiating the purchase of M-346 training aircraft with Italy. These are not symbolic gestures — they are the beginnings of a transformation of Canada's defense posture. They fit within the NATO 3.0 logic that Rutte and Hegseth are calling for.

The importance of transatlantic coherence

The realization of the 5% target depends, ultimately, on transatlantic coherence of effort. If the United States maintains its pressure but European allies absorb it without truly changing their trajectory, the target will remain aspirational. If, on the contrary, American pressure aligns with a European and Canadian conviction that security has a real price — and the war in Ukraine has made that bloody demonstration — then the trajectory toward 2035 can hold. This is not guaranteed. But it is possible. And the 90 additional billion of 2025 show that the momentum is there.

What is at stake at the Ankara summit, at bottom, is the question of whether NATO can transform external pressure (American and Russian) into internal conviction (European). That is: can European democracies explain to their citizens why spending 5% of GDP on defense is necessary, not because Trump demands it, but because their own security — and that of their children — depends on it? This is a political conversation that few leaders have yet had with the frankness it deserves.

The signal sent to Moscow and Beijing

Deterrence through figures

The commitment toward 5% of GDP is not only an internal NATO budget exercise. It is a signal sent to two potential adversaries: Russia and China. To Moscow, this signal says: we are rearming beyond what was imaginable. If you continue down the escalation path, you will face an Alliance that becomes progressively stronger, not weaker. This long-term deterrence logic is at the heart of Rutte's strategy and his allies'. It does not address the short term of the war in Ukraine. But it sketches the geopolitical context in which any peace negotiation will have to fit.

For Beijing, the signal is more complex. China observes Europe's defensive transformation with strategic interest. It knows that if NATO allies reach 5% of GDP, American capacity to concentrate on the Indo-Pacific increases — since Europe becomes more autonomous in its own defense. This frees American resources to face Chinese ambitions in the Pacific. NATO's commitment toward 5% of GDP is therefore also, indirectly, a strategic message to Beijing: the West is restoring its global strategic coherence.

NATO's role in industrial production

The Alliance as industrial coordinator

An often underestimated aspect of the process toward 5% is the role NATO itself plays as industrial coordinator. At the Ankara summit, allies will commit to strengthening the transatlantic defense industrial base, according to the priorities defined on June 18, 2026. This includes mechanisms for ammunition standardization, collective orders, production license sharing and joint development. These mechanisms allow saving resources while increasing production.

The PURL mechanism for Ukraine is a model applicable to allied defense more broadly. If allies can organize to collectively buy American equipment for Ukraine, they can also organize to collectively buy equipment for their own armies — achieving economies of scale and reducing delays. The Czech ammunition initiative is another example: sourcing ammunition on the global market in a coordinated fashion produces better conditions than fragmented purchases. These collective approaches are the key to converting budgets into real capabilities.

Ukrainian innovation as accelerator

Ukrainian military innovation has played an unexpected role in accelerating the European defense industrial base. Ukraine produced 4.5 million drones in 2025, according to Modern Diplomacy of June 2, 2026. It has developed cruise missiles, electronic warfare systems, autonomous ground vehicles. This combat expertise, tested in real conditions, is precisely what European defense industries cannot produce in peacetime. Ukraine-Europe industrial partnerships — like the Quantum Frontline Industries project (Frontline Robotics Ukraine + Quantum Systems Germany) launched in December 2025, or the LEAP project mentioned earlier — allow transferring this expertise to European production chains.

This co-production model with Ukraine may be the most effective response to the problem of converting budgets into capabilities. Rather than rebuilding from scratch defense industries that have lost their expertise, Europeans can rely on Ukraine — which has the expertise but not necessarily industrial scale capacity. The combination of both — Ukrainian expertise + European industrial capacity — could be the fastest path to capable forces. And it simultaneously reinforces Ukrainian defense and the European industrial base. This is a synergy that neither Moscow nor Beijing had anticipated.

The governance of commitment: who verifies?

The verification problem

A collective commitment of 32 nations toward 5% of GDP is as strong as its verification mechanism. NATO publishes annual defense spending statistics for its members. These statistics are largely transparent and comparable. But they rely on national declarations and a shared definition of what counts as defense spending. This definition can be broadened or narrowed according to national interpretations. The risk of creative accounting is real and documented in the history of previous commitments to 2% of GDP.

Hegseth's American posture review constitutes an external, informal verification mechanism — potentially more rigorous than NATO's official publications. But it is unilateral and subject to the political priorities of the current American administration. More robust verification would require an institutional mechanism internal to NATO, with qualitative criteria (deployable forces, operational equipment, acquisition timelines) in addition to quantitative criteria (GDP percentage). This mechanism does not yet exist in its definitive form. The Ankara summit should establish it.

The role of public transparency

Beyond institutional mechanisms, public transparency plays a role in verifying defense commitments. Media, think tanks, national parliaments scrutinize budgets. Organizations like the Stockholm International Peace Research Institute (SIPRI), whose data is widely cited, publish annual comparisons. This transparency creates reputational pressure on governments that do not keep their commitments. It is not infallible, but it is a counterweight to the temptations of opacity.

In this context, journalists, analysts and columnists have a role to play: maintaining pressure by recalling figures, comparing promises to deliveries, flagging gaps. This is not pleasant for the governments concerned. But it is one of the essential functions of a free press in a democracy deciding to rearm. The commitment toward 5% of GDP must not disappear into budget drawers. It must be kept visible, weighed, contested, improved. This is the role of democratic civil society facing the strategic urgency of our era.

The LEAP project: innovation as a force multiplier

When investment goes beyond tanks and missiles

The LEAP project — Long-term European Armaments Programme — represents an attempt by the European Union to coordinate defense investments beyond conventional equipment purchases. Officially launched in February 2026, this framework acknowledges a reality that simple GDP percentages do not capture: it is not only how much you spend that matters, but where you spend and how investments from different countries reinforce each other. The war in Ukraine has demonstrated brutally that the capacity to produce FPV drones at scale, to maintain logistics chains under pressure and to integrate real-time intelligence into tactical decisions is at least as important as the number of tanks in service. LEAP attempts to formalize these lessons in a coordinated investment architecture for the 27 European Union members.

The central challenge of the LEAP project is political as much as technical. Each member nation has its own defense industries, its own employment priorities and its own relationships with major contractors. France protects Dassault and Thales. Germany wants Rheinmetall at the heart of European rearmament. Poland prefers buying American to maximize Washington's political commitment to its defense. These national logics do not simply disappear because they are confronted with a 5% of GDP objective. LEAP must therefore navigate between collective ambition and national realities — a tension that even the argument of common survival does not completely erase.

R&D as strategic investment, not expense

In current calculations of NATO defense spending, research and development (R&D) is often underrepresented. Yet this is where the long-term competition with Russia and especially China plays out. Beijing is investing massively in military artificial intelligence, autonomous systems, hypersonic missiles and next-generation electronic warfare. If NATO reaches 5% of GDP by massively buying equipment designed in the 2000s, it will have spent a great deal of money for a strategic posture already outdated. The 5% objective only makes sense if a significant proportion — at least 20% according to several SIPRI experts — is allocated to R&D and breakthrough innovation.

The Ukrainian example is illuminating here. In the space of three years, Ukraine has developed a combat drone industry capable of striking targets more than 1,000 km deep in Russian territory. This is not the result of a conventional acquisition program — it is the product of an absolute necessity that unleashed remarkable creativity and industrial agility. NATO allies are not in an existential war, but they must find institutional mechanisms to reproduce this agility without needing a crisis to provoke it. LEAP is an attempt in this direction. The question is whether EU bureaucratic structures will truly enable this agility or drown it under layers of procurement procedures.

Canada and the 150 billion commitment: a change of culture or of figures?

Canada's history with allied burden-sharing

Canada has long been the perfect example of a NATO free rider — a stable, prosperous and respected democracy that benefited from the American security umbrella without paying its fair share. For decades, Canadian defense spending hovered around 1% of GDP, well below the 2% objective. American pressure, particularly under the Trump administration, has finally produced a historic commitment: $150 billion Canadian over ten years to modernize the Canadian Armed Forces. This amount is real, but it must be contextualized. In US dollars, this represents approximately $110 billion — a fraction of what the United States spends in a single year. And it is spread over a decade, meaning the real capability effects will only be visible by the mid-2030s.

What may be more important than the figure itself is the cultural transformation it represents. For generations, the Canadian debate on defense was dominated by two reflexes: the reassuring proximity with the United States and a tradition of multilateral peacekeeping inherited from the Lester Pearson era. Both reflexes are being simultaneously challenged. The geopolitics of 2026 no longer allow the luxury of half-measures. If Canada wants a say in NATO decisions — including on Hegseth's posture review — it must first demonstrate it takes its commitments seriously. The announcement of $150 billion is a first step. It is only a first step.

The multiplier effect of North American contributions

In NATO's architecture, member state contributions do not simply add up — they multiply through interoperability, combined exercises and shared capabilities. When Canada invests in F-35 fighters, these aircraft are immediately interoperable with American, British and other allied forces using the same platform. When Poland buys American Abrams tanks, it reinforces its compatibility with NATO deployment plans in central Europe. These multiplier effects are difficult to quantify but fundamental for the Alliance's operational effectiveness. This is why the 5% of GDP objective cannot be reached any which way — investments must be coordinated to produce genuinely collective capabilities rather than juxtaposed national forces.

Canada has a unique opportunity in this context. With its geographic position between the United States and the Arctic — a strategic region of growing importance as Russia and China project power there — Ottawa can invest in capabilities that fill a real gap in the Alliance's posture. Arctic defense, advanced warning systems and submarine capabilities are areas where the $150 billion Canadian could have a strategic effect well above their nominal cost. The question is whether the Canadian political class is ready to make these difficult choices rather than spreading the envelope across multiple small projects that satisfy electoral constituencies without truly transforming capabilities.

The strategic signal to Moscow and Beijing: credibility as weapon

What adversaries read in defense figures

Analysts at the Kremlin and at the People's Liberation Army read NATO defense budgets with meticulous attention. What they seek is not simply the number of tanks or missiles — they seek signals about the political will of Western democracies to sustain costly and unpopular defense efforts over the long term. For years, European spending stagnation gave them an encouraging signal: the incredibly wealthy democracies of Europe preferred financing their welfare states rather than their armies. The trajectory toward 5% of GDP by 2035, if maintained with credibility, reverses this signal fundamentally.

Moscow has already adjusted its calculations since the 2022 invasion. Ukrainian resistance, backed by Western aid, demonstrated that democracies can sustain substantial support over several years. But Vladimir Putin still bets on long-term exhaustion — on the idea that the 2024 and 2026 elections will weaken Western cohesion. If 5% of GDP commitments are institutionalized in national laws and binding multi-year procurement plans, they become far harder to reverse with electoral alternations. This is precisely why the governance of commitment — who verifies, who sanctions, who is accountable — matters more than the figure itself.

Enhanced deterrence as message to Beijing

China observes the NATO debate with particular strategic interest. Beijing constantly calculates the cost of military action against Taiwan or in the South China Sea. If Western democracies — particularly the United States and their European allies — demonstrate through defense investments that they are serious for the long haul, this raises the perceived cost of direct confrontation. Reaching 5% of GDP by NATO members is therefore a signal that extends well beyond the sole question of European security. It is a global message about democratic cohesion in the face of expansionist autocracies.

The symmetrical risk is also real. If democracies massively rearm without accompanying that effort with active diplomacy and an arms control architecture, they may feed an action-reaction spiral that raises the risk of conflict through accident or miscalculation. The INF, New START and Open Skies treaties have all collapsed. The diplomatic space for managing military risks is today dangerously reduced. 5% of GDP in defense without parallel investment in preventive diplomacy would be a pyrrhic victory. The objective is not to prepare for war — it is to make war so costly for the adversary that it does not occur. This nuance is fundamental, and it risks getting lost in the noise of budget announcements.

Conclusion: A figure that commits a generation

2035: a target, not a guarantee

The target of 5% of GDP by 2035 is ambitious, necessary, and conditionally achievable. Ambitious: it demands budget transformations unprecedented in peacetime. Necessary: the threats posed by Russia, China and other actors make substantial rearmament unavoidable. Conditionally achievable: if political will holds, if industries transform, if acquisition processes accelerate, if supply chains diversify. Many conditions. But no technical or economic impossibility.

What is certain: the process underway is already transforming the Alliance. The 90 additional billion of 2025 are real. Equipment orders placed in 2025-2026 are real. Industrial partnerships with Ukraine are real. The collective commitment toward 5% has changed the political frame of reference for defense in Europe. Even if some allies do not reach the target by 2035, the Alliance will be significantly stronger than it was in 2024. And in a world where credible strength is the only language autocrats understand, this transformation matters.

Generational responsibility

The commitment toward 5% of GDP is, ultimately, a generational commitment. It is today's governments making decisions whose effects will be felt for ten years — on budgets, on industries, on military capabilities. But it is also today's citizens who will fund this effort through their taxes, sometimes at the expense of other social priorities. This reality deserves to be stated plainly: security costs. And in a democracy, it is the citizen who pays. Transparency about this cost — as about its alternatives — is the minimum condition for informed consent. NATO can set targets. Only democracies can fund them sustainably.
