ReArm Europe, the €800 billion bet that must wake up the West

Introduction: a number that changes the strategic equation

800 billion euros, a symbolic threshold

The ReArm Europe program, launched by the European Commission, aims to mobilize up to €800 billion to push member states' defense spending to a level unseen since the end of the Cold War. That figure, enormous on paper, reflects a belated but genuine reckoning: Europe can no longer afford to outsource its security to an American ally growing more unpredictable under Donald Trump.

The stated goal is to push European Union member states' defense spending toward 5% of GDP, a level that would have sounded fanciful just five years ago, before Russia's 2022 invasion of Ukraine. A €150 billion lending instrument has already been approved to finance concrete arms purchases by member states, proof that this ambition goes beyond a mere announcement.

A NATO summit under high tension in Ankara

This European rearmament unfolds against the backdrop of the NATO summit in Ankara, where the defense ministers of allied nations reaffirmed their commitment to reach 5% of GDP by 2035, with some countries pledging to get there well ahead of schedule. NATO Secretary General Mark Rutte noted at a press conference that European allies and Canada have already increased spending by more than $139 billion in nominal terms compared to the previous year.

This massive budgetary momentum illustrates a profound paradigm shift within the Atlantic Alliance: the era when Europe could settle for symbolic defense spending, sheltering under the American umbrella, now clearly belongs to the past.

The Commission's five flagship projects

A cross-border industrial architecture

The European Commission has proposed five major cross-border defense projects, an initiative meant to pool the industrial capacities of member states rather than let each nation develop its own arms programs in isolation. This approach aims to fix one of the historic structural weaknesses of European defense: an industrial fragmentation that multiplies costs and delays the rollout of modern equipment.

These projects span fields as varied as air defense, drones, military mobility, and munitions — sectors where Europe has fallen significantly behind the United States and, in some segments, even China. Pooling resources theoretically lowers unit costs while strengthening interoperability among national armies.

The challenge of turning plans into action

As impressive as the stated ambition is, the real test remains whether member states can convert these financial commitments into tangible military capabilities. The recent history of European defense cooperation is littered with ambitious projects that eventually bogged down in endless negotiations between countries with diverging industrial priorities.

The success of ReArm Europe will largely depend on whether national governments are willing to prioritize the collective European interest over their own industrial champions — a balancing act that has often failed in the past, notably between France and Germany on projects like the future combat aircraft.

Trump, an unpredictable ally but a catalyst for resolve

American pressure that is bearing fruit

Let's be honest about it: the pressure exerted by Donald Trump on European allies, however blunt and at times humiliating in its delivery, has produced an undeniable accelerating effect on the continent's rearmament efforts. The American president has repeatedly insisted that European countries must shoulder a far greater share of their own defense burden, a position that, at its core, is not without strategic logic.

This American demand, voiced with the bluntness typical of Trump's style, paradoxically served as the trigger for a European awakening that would likely have taken years longer to emerge without this direct, and often uncomfortable, outside pressure.

An alliance that remains solid despite political turbulence

Despite Trump's repeated criticism of NATO, operational military cooperation between the United States and its European allies remains remarkably robust on the ground, as shown by the numerous joint exercises held this year. This dissonance between Washington's political rhetoric and battlefield reality reflects an institutional resilience unique to the Atlantic Alliance, which has weathered decades of transatlantic tension without ever breaking apart.

On the strictly military front, the Western posture remains solid, buoyed by rising investment from European countries that, under duress, are rediscovering the strategic importance of credible deterrence against threats from the East.

Russia, a structuring threat behind every decision

Putin, the shadow looming over every summit

Behind every budgetary decision tied to ReArm Europe looms the shadow of Vladimir Putin and his army, which continues, more than four years after the February 2022 invasion, to wage a brutal war of attrition against Ukraine. That war has brutally exposed European capability gaps, particularly in munitions production, a sector where the continent found itself unable to keep pace with consumption rates seen on the Ukrainian front.

Intelligence services in several European countries believe Russia could, in the coming years, test the solidity of the Atlantic Alliance on its eastern flank, particularly in the Baltic states — a scenario that alone justifies accelerating investment in air defense and military mobility.

Ukraine, a painful laboratory of modern military lessons

The courage of the Ukrainian people and their president, Volodymyr Zelensky, in the face of Russian aggression has, unwittingly, provided an open-air laboratory of military lessons that Europe must now fold into its own defense doctrine: the importance of drones, the vulnerability of tanks to modern anti-tank systems, and the absolute necessity of munitions stockpiles sufficient to sustain a long fight.

This war, tragic for the Ukrainian people who pay its human cost daily, has at least had the merit of forcing Europe out of its post-Cold War strategic torpor — a torpor that could have proven fatal against an adversary who never stopped building up its military capabilities.

China, a quiet but growing threat

A systemic rival watching Western weakness

While Russia represents the most immediate and visible threat to European security, China remains, over the medium and long term, the most formidable systemic rival for the entire Western world. Beijing is closely watching whether Europe and the United States can sustain a credible deterrence posture, lessons it could apply to its own regional strategy, particularly toward Taiwan.

This Chinese dimension of European rearmament is often underestimated in public debate, even though decisions made today in Brussels on defense will have direct repercussions on the overall credibility of Western deterrence against the full range of revisionist powers, from Moscow to Beijing, by way of Tehran and Pyongyang.

A technological competition that goes beyond the military sphere

European rearmament isn't limited to buying tanks and missiles: it also encompasses a crucial technological dimension, notably in military artificial intelligence, autonomous drones, and cybersecurity systems — sectors where China has been investing massively for years with an openly declared goal of global technological supremacy.

The challenge for Europe, then, is not to settle for a purely quantitative rearmament, but to invest decisively in the breakthrough technologies that will shape the balance of military power in the coming decades, or risk falling technologically behind more agile adversaries.

The central role of Europe's defense industry

Order books that are exploding

Europe's defense manufacturers, from Rheinmetall to Thales, by way of Leonardo and Dassault Aviation, are direct beneficiaries of this unprecedented wave of investment, with order books reaching historic highs. This industrial boom, widely applauded by financial markets, is the concrete economic translation of Europe's new rearmament doctrine.

This growth in the defense sector, however, comes with a major capacity challenge: European factories must now significantly ramp up production rates, a process requiring heavy industrial investment and timelines measured not in months but often in years.

The risk of persistent dependence on the United States

Despite this growing European industrial capacity, certain strategic systems — notably the most advanced missile defense systems and some critical electronic components — remain heavily dependent on American technology, a reality that, for now, limits the full strategic autonomy that some European leaders are calling for.

This residual dependence is a vulnerability that European officials are actively working to reduce, without calling into question the fundamental transatlantic cooperation that remains, despite current political tensions, the bedrock of Western security.

The Baltic states, the West's forward outpost of vigilance

A region living under constant threat

The Baltic states — Estonia, Latvia, and Lithuania — remain, given their direct geographic proximity to Russia, the territories most exposed to any potential escalation by the Kremlin. An American general recently reaffirmed that the United States would stand alongside its European allies in defense of the Baltics, a reassuring commitment amid persistent doubts over American reliability.

That statement, delivered directly from Estonian soil, was explicitly meant to reassure populations who live daily with an acute awareness of their geographic vulnerability facing a Russian neighbor that has never abandoned its imperial ambitions over its former Soviet sphere of influence.

Strengthening the allied military posture in the region

NATO has recently assigned an additional headquarters to the Baltic region, a decision that concretely reflects the Alliance's determination to reinforce its military presence in this sensitive strategic zone, seen by many analysts as the most likely flashpoint in a direct confrontation with Moscow.

This reinforcement comes alongside regular military exercises involving troops of multiple nationalities, a demonstration of allied cohesion designed both to reassure local populations and to deter any temptation toward military adventurism on the part of the Kremlin in this particularly sensitive region.

Tensions within the Alliance, a risk not to be underestimated

Persistent divergences among allies

Despite the show of unity at official summits, real divergences persist among NATO member states over exactly how financial efforts should be distributed and which industrial priorities should take precedence. Some southern European countries, less directly exposed to the Russian threat, show a weaker budgetary appetite than their counterparts in Eastern or Northern Europe.

These divergences, though rarely aired publicly with the same bluntness as American criticism, represent a potential fragility for the long-term cohesion of European rearmament, in a context where surface unity must urgently translate into concrete budgetary convergence.

The touchy question of burden-sharing

The equitable distribution of the financial burden among member states remains a recurring point of friction, with some wealthier states feeling they contribute disproportionately compared to partners whose budgetary commitment remains, on paper, below the targets collectively set at successive Atlantic Alliance summits.

This question of burden-sharing, far from new, has taken on a particularly sharp dimension since Trump's arrival at the White House, as he has made it a central plank of his recurring criticism of NATO's European allies.

The indirect testimony of defense experts

A cautious but optimistic reading from analysts

Several defense specialists, cited in the international press ahead of the NATO summit in Ankara, note that the scale of investment announced under ReArm Europe represents a potentially historic turning point for Europe's military posture, provided these financial commitments actually translate into concrete equipment deliveries within a reasonable timeframe.

These experts also stress the importance of not neglecting the human dimension of rearmament: recruiting, training, and retaining European soldiers, a major demographic challenge in aging societies where the appeal of military careers has generally declined compared to previous decades.

The limits of premature optimism

It would nonetheless be premature, according to these same analysts, to declare victory too quickly: turning an €800 billion budget envelope into truly operational military capabilities will take several years, if not a full decade — a period during which Russia could seek to exploit any lingering windows of vulnerability.

This long timeline is, in itself, a major strategic challenge for Europe, which must now manage both the immediate urgency of deterrence against Russia and the slower timeline of rebuilding its defense industrial base.

The drone, the new backbone of the battlefield

A Ukrainian lesson taken seriously

The war in Ukraine has demonstrated, almost brutally, that cheap drones can neutralize expensive armored equipment, a lesson European general staffs are now folding into their procurement doctrines under ReArm Europe. This doctrinal shift explains why a growing share of national budgets is flowing toward unmanned systems rather than traditional heavy platforms.

Several European countries, including Germany and Poland, have announced massive orders of reconnaissance drones and loitering munitions, a category of weaponry nearly absent from European arsenals just five years ago and now an openly acknowledged industrial priority.

North Korea, Moscow's silent accomplice

Military support that worries Western capitals

Western intelligence services have repeatedly confirmed the deployment of North Korean troops and munitions in support of Russia's war effort, direct military cooperation between Pyongyang and Moscow that reflects the formation of an increasingly structured authoritarian axis facing the West. This alliance of convenience reinforces the need for Europe to stop thinking solely in terms of an isolated Russian threat.

This cooperation between authoritarian regimes, which also includes two-way technology transfers, confirms that European rearmament is not a response to a single, localized threat, but to a broader shift in the international order toward a systemic confrontation between democracies and authoritarian regimes.

Iran, drone supplier and self-declared accomplice of the Kremlin

Deliveries that have changed the face of the war in Ukraine

Iranian-made Shahed drones, used extensively by the Russian military against Ukrainian civilian and energy infrastructure, have forced Europe to urgently invest in short-range air defense systems capable of intercepting swarms of cheap munitions. This threat, long underestimated, now occupies a central place among ReArm Europe's acquisition priorities.

Military cooperation between Tehran and Moscow illustrates, once again, the convergence of regimes hostile to the liberal international order, a reality that is pushing European strategists to design their rearmament not as a response to a single threat, but as preparation for a lasting multipolar confrontation.

The diplomatic role of France and Germany

A Franco-German engine that sometimes stalls

France and Germany, traditionally the engines of European integration, sometimes struggle to agree on major joint arms contracts, as shown by the complex negotiations surrounding the future air combat system. These bilateral tensions, though rarely covered with the same intensity as American criticism, slow the concrete implementation of certain parts of ReArm Europe.

Despite these industrial frictions, Paris and Berlin continue to publicly affirm their determination to achieve genuine European strategic autonomy, a long-term goal that will require setting aside national industrial egos in favor of a more ambitious collective vision.

Toward a more autonomous European defense doctrine

A strategic ambition that goes beyond the budget alone

Beyond the budgetary question alone, ReArm Europe reflects a broader ambition: that of a more coherent and autonomous European defense doctrine, capable of complementing, and eventually partially substituting for, the historically central American protection within NATO. This ambition, still nascent operationally, nonetheless marks a significant political inflection.

This doctrinal evolution comes alongside a broader reflection on the European governance of defense, with recurring debates over creating a genuine integrated European army, an ambitious project that still runs into resistance from several member states attached to their national military sovereignty.

A test of credibility for decades to come

The success or failure of ReArm Europe will largely determine Europe's credibility as an autonomous strategic actor capable of defending its own security interests, independent of the vagaries of American elections that could, in the future, bring to power leaders even less inclined than Trump to support the Atlantic Alliance.

This long-term strategic deadline imposes on European leaders a budgetary and political discipline rarely observed in the past, a collective governance challenge that will test the real solidity of the European project against centrifugal national pressures that have never entirely disappeared from the continental political landscape.

Conclusion: a date with history that Europe cannot miss

A strategic window that won't stay open forever

The ReArm Europe program represents far more than a simple budget envelope: it symbolizes the still-fragile but genuine attempt by a European continent rediscovering the importance of its own military sovereignty in an increasingly dangerous world, marked by Russian aggression, Chinese ambition, and American unpredictability under Donald Trump's presidency.

This strategic window, opened by the exceptional convergence of the war in Ukraine and American pressure, will probably not remain open indefinitely: it is now, not in ten years, that Europe must prove its ability to turn budgetary ambitions into genuine, credible military power.

The legacy this generation will leave the next

The decisions made today in Brussels and Ankara will determine the security of the European continent for decades to come, a strategic legacy for which today's generation of leaders will bear full responsibility before history, whether it amounts to a successful rearmament or, conversely, a missed opportunity with potentially dramatic consequences.

Ukraine is fighting today for its survival against Russian aggression; Europe is fighting, more quietly but just as fundamentally, to preserve its ability to decide its own security destiny in a world where force remains, unfortunately, a language some regimes understand better than diplomacy.

Columnist's transparency note

Who I am and my acknowledged biases

I sign my pieces as a columnist, not as a neutral reporter. My lens is clearly pro-Western, pro-Ukraine, and supportive of a committed European rearmament against identified threats, whether from Moscow, Beijing, Tehran, or Pyongyang. On Trump, I apply a nuanced reading: I credit his pressure when it produces concrete military results for NATO, without endorsing his domestic policy on other issues.

I have no financial or professional ties to Europe's defense industry, and I rely exclusively on verifiable public sources to build my analysis.

What I don't know and my method

I cannot guarantee that the announced €800 billion will fully translate into operational military capabilities: that uncertainty is an inherent part of forward-looking analysis in defense matters. My method consists of cross-referencing official primary sources with analysis from recognized experts, systematically flagging areas of uncertainty rather than hiding them behind false certainty.

I remain open to revising my analysis should facts on the ground come to contradict currently observed trends in European rearmament.
