ReArm Europe: Security at What Price?
The ReArm Europe program is a newly proposed European Union defense financing initiative launched in early 2025 in response to heightened security concerns. European Commission President Ursula von der Leyen unveiled this plan amid an extraordinary EU summit focused on defense and the war in Ukraine. The proposal would allow EU member states to collectively mobilize up to €800 billion in additional military spending over the coming years. Central to the plan is a €150 billion EU loan facility to help finance joint defense investments – targeting critical capabilities like air and missile defense systems, drones, artillery, and ammunition. This unprecedented surge in funding reflects a dramatic policy shift: after decades of relatively modest defense outlays, European leaders now declare that “Europe is ready to massively boost its defence spending”, entering what von der Leyen calls “an era of rearmament”. The ReArm Europe initiative aims to strengthen Europe’s military posture and reduce reliance on external allies, but it also raises important questions about militarization, economic trade-offs, and the balance between security and sustainability.
Accelerating Militarization: Risks and Consequences
A critical concern surrounding ReArm Europe is the risk of accelerating militarization across the continent. Europe’s military expenditure has already been rising sharply in recent years, even before this new plan. According to the Stockholm International Peace Research Institute (SIPRI), European countries spent a combined $588 billion on military purposes in 2023, a 16% increase from the previous year and 62% higher than in 2014. Several EU member states – France, Germany, and the UK (the latter now outside the EU) – already rank among the world’s top defense spenders. This trend reflects genuine security concerns, particularly after Russia’s invasion of Ukraine, but it also fuels worries that Europe is entering an arms race dynamic. Critics argue that a massive infusion of funds into armies and weaponry could entrench a cycle of militarization with unpredictable consequences.
One potential consequence is the escalation of international tensions. Moscow has already denounced the EU’s defense surge, with the Kremlin describing Europe’s €800 billion rearmament plan as a troubling step towards further militarization of the region. There is a fear that as European countries pour resources into arms, rival powers may respond in kind, undermining efforts at diplomacy and arms control. Another concern is the opportunity cost of military spending. Humanitarian and development advocates warn that increasing defense budgets often comes at the expense of social programs and global aid. For example, Mexico’s delegate to a recent UN disarmament forum expressed “grave concern that several countries have announced their intention to reduce development aid while increasing military spending,” noting that diverting resources to militarism will “inevitably send the world crashing into more violence, more destruction, more poverty”. In other words, excessive rearmament could erode investments in economic development and social welfare, both within Europe and abroad, potentially exacerbating instability.
It is also worth noting that some experts question the very premise that Europe is “under-armed.” Peace and disarmament advocates point out that Europe is already heavily armed by historical standards. As one analyst bluntly observed, “the idea that Europe is not already heavily militarised is absurd.” The data support this: Europe (as a region including EU and NATO allies) now accounts for about 24% of global military expenditure. This context raises a cautionary point: while improving defense readiness is important for security, rushing to rearm on such a vast scale could overshoot actual needs, leading to excessive stockpiling of weapons and heightened risks of misuse or proliferation. A more militarized Europe might also shift the political climate – for instance, empowering hardline nationalist elements or marginalizing diplomatic solutions – an outcome some observers find “incredibly alarming” in the current climate.
Economic Implications of ReArm Europe
Implementing the ReArm Europe program carries significant economic implications, especially given Europe’s existing economic challenges. The plan’s headline figure – €800 billion – is enormous, equivalent to roughly five years of Germany’s total defense budget or nearly the entire annual GDP of the Netherlands. Mobilizing such sums will test the economic strength and unity of the EU. While the Commission’s proposal encourages repurposing existing EU funds and allowing national defense outlays to bypass normal fiscal limits, member states would still shoulder the vast majority of the spending. This comes at a time when many European economies are still recovering from the COVID-19 pandemic, grappling with high public debt levels, and navigating an energy crisis and inflationary pressures triggered by the war in Ukraine.A key question is how to finance this defense buildup without jeopardizing economic stability. The European Commission has suggested creative budgeting techniques – for example, invoking Article 122 of the EU Treaty (an emergency provision) to set up the €150 billion defense investment fund outside the normal EU budget process. It also floated exempting defense expenditures from EU deficit rules, effectively giving countries more fiscal space to spend on their militaries. Indeed, von der Leyen noted that if each member state raised defense outlays by an average of 1.5% of GDP, it would “create fiscal space of close to €650 billion over four years” under relaxed budget rules. These measures signal a willingness to bend traditional fiscal constraints for the sake of security. However, not all EU members agree on this approach. Officials from financially conservative governments (so-called “frugal” states) have voiced concern that loosening the purse strings on defense could set a precedent undermining fiscal discipline. Joint EU borrowing for defense – strongly advocated by countries like France and Poland – has been opposed by others such as Germany and the Netherlands, who fear being left to shoulder debts incurred by others.
Beyond budgeting debates, there is the issue of macroeconomic impact. On one hand, advocates of the defense plan argue that it could stimulate Europe’s economy. Large defense investments might create jobs in arms manufacturing, spur technological innovation (in areas like aerospace, cyber, and AI), and reduce strategic vulnerabilities (e.g. by strengthening the European defense industry). In fact, analysis by former ECB President Mario Draghi’s expert committee suggests that increased defense and high-tech investment is part of a broader strategy to revive European competitiveness. The Draghi report notes Europe has lagged in next-generation industries and warns that boosting sectors such as defense manufacturing and digital tech could help drive productivity and growth. Viewed in this light, ReArm Europe might serve as a form of fiscal stimulus, channeling idle savings into industrial activity and innovation. Notably, stock markets reacted positively to news of the EU defense package – the Europe-wide aerospace and defense index jumped on anticipation of higher spending.
On the other hand, economic risks are very real. Expanding defense budgets by hundreds of billions means diverting resources from other priorities or taking on new debt – both of which carry opportunity costs. Many European countries already face stretched public finances; for example, Italy and Greece have debt-to-GDP ratios around 135–155%, limiting their room for additional borrowing. If not carefully managed, a defense spending spree could widen budget deficits or force cutbacks in social programs down the line. There is also the inflation factor: Europe’s inflation rate spiked to multi-decade highs in 2022–2023, and although it has begun to ease, the cost of military equipment has been rising faster than general inflation. A RAND analysis warned that persistent inflation could erode European defense budgets by around $300 billion between 2022 and 2026, effectively nullifying much of the planned increase in spending power. Already, the real purchasing power of defense euros is under pressure – for instance, the UK Ministry of Defence recently identified a $21.5billion shortfall in its equipment plan due to surging costs. This means EU governments might have to spend far more than €800 billion on paper to achieve the desired boost in capabilities, putting additional strain on taxpayers. As policy analyst Lucas Guttenberg observed, the Commission’s current plan is “trying to make sure fiscal policy does not stand in the way of defence policy,” but it does so in a “short-termish way” and leaves the question of long-term funding for Europe’s security open. In sum, ReArm Europe presents a delicate balancing act: it must provide enough money to meaningfully strengthen defense, yet not destabilize national finances or crowd out economic investments in other vital areas.
Europe’s Current Defense Capabilities: A Strong Starting Point
Any assessment of ReArm Europe must consider Europe’s existing defense capabilities, which are significant. The EU is not starting from a position of military weakness; on the contrary, European nations collectively field one of the most powerful military forces in the world. The 27 EU member states together spent about €326 billion on defense in 2024, roughly 1.9% of the EU’s GDP on average. If we include close allies like the United Kingdom (which left the EU but remains part of Europe’s security architecture), the total European defense expenditure is even higher – second only to that of the United States globally. In fact, NATO’s European members combined outspent even rising powers like China and Russia in 2023
Europe’s defense budgets have financed capable conventional forces: advanced air forces with fourth- and fifth-generation fighter jets, modern naval fleets, well-trained armies, and substantial stocks of armored vehicles and artillery. European countries also have strong domestic arms industries producing submarines, satellites, missile defense systems, and other sophisticated hardware.
Crucially, Europe possesses an independent nuclear deterrent – a factor sometimes overlooked in discussions about its security. France, an EU member, is a nuclear-armed state with an arsenal of approximately 290 nuclear warheads. This means that the EU, via France, has an ultimate deterrence capability against existential threats. French nuclear forces (complemented by the United Kingdom’s nuclear arsenal outside the EU framework) provide a powerful insurance policy: any adversary contemplating aggression against Europe must factor in the risk of nuclear retaliation. This reality underpins the argument made by some analysts that Europe is already capable of defending itself against major threats, even without a massive expansion of conventional forces. For example, former Polish Prime Minister Donald Tusk recently noted that Europe’s security “depends first and foremost on us… on condition Europe finally believes in its own strength,” implying that Europe’s economic and technological power can translate into adequate defense. With an economy nine times the size of Russia’s and a combined military might that includes two of the world’s top ten military spenders (France and Germany), the EU is far from helpless in ensuring its security.
Balancing Defense Readiness with Economic Sustainability
The overarching challenge for the ReArm Europe initiative is finding the right balance between enhancing defense readiness and maintaining economic sustainability. On one side of the equation is the pressing need for security: Europe faces genuine threats in its neighborhood (a revanchist Russia, instability to the south, cyber and hybrid attacks) and can no longer assume unlimited American protection. The Ukraine war underscored that Europe must be prepared to act decisively in its own defense. From that perspective, boosting defense investment is seen as necessary insurance – a cost that, if it prevents future conflicts or deters aggression, will pay itself back many times over. Indeed, a study by the Kiel Institute found that the costs to countries like Germany would be far greater (in economic disruption and required military response) if Russia were to succeed in conquering Ukraine, compared to the cost of helping Ukraine and strengthening NATO now. This reinforces the idea that a certain level of defense spending is not only affordable for Europe but economically prudent in the long run, by averting even costlier security crises.
On the other side of the equation, economic sustainability and social cohesion are vital components of security in the broad sense. Europe’s strength has always flowed as much from its economic vitality and social model as from its military hardware. If excessive defense spending were to undermine economic growth, trigger financial instability, or force painful austerity measures on welfare, it could ironically weaken the very foundations of European security. Thus, EU leaders have to calibrate the ReArm Europe program carefully. This means prioritizing efficiency and value-for-money in defense procurement – for example, pooling resources to avoid duplication, investing in joint projects that benefit multiple countries, and ensuring competition and transparency in how funds are used. A euro spent on defense should ideally serve a dual purpose: improving security while also stimulating innovation and industrial development that feed back into the economy. Some analysts suggest focusing on areas with high spillover benefits (like cyber defense, space, and advanced manufacturing) so that military spending contributes to civilian economic progress as well. Such an approach could help reconcile the apparent conflict between “guns and butter.”
The ReArm Europe program marks a historic pivot in European policy, aiming to significantly reinforce the EU’s defense capacity in an uncertain world. From a critical perspective, this initiative carries both promise and peril. The promise lies in a stronger, more autonomous Europe that can deter aggression and protect its interests without compromising its economic vitality. The peril lies in the potential for overspending, militaristic overreach, or the neglect of other priorities, which could inadvertently weaken Europe from within. Europe today is already a military heavyweight with ample means to defend itself – including nuclear deterrence and some of the world’s largest defense budgets – so any further expansion of its military power must be justified by clear-eyed assessments of security needs and conducted in tandem with strategies to keep the economy robust. As the EU moves forward with ReArm Europe, balancing these considerations will be key. Leaders must remain vigilant that in arming for security, they do not disarm the economy, and that Europe’s long-held values of peace and prosperity remain at the forefront. The coming years will test the EU’s ability to integrate strength with stability, but with prudent management and continued unity, it is possible for Europe to reinforce its defenses while safeguarding its economic future – achieving a state of security that is sustainable in every sense of the word.
