After Vladimir Putin launched Russia’s full-scale invasion of Ukraine in 2022, Europe entered a period of strategic uncertainty not seen since the Cold War. What once felt like a distant geopolitical rivalry has evolved into a direct and prolonged conflict on the continent’s doorstep. At the same time, signals from the United States have grown sharper and more demanding, pressing European governments to shoulder a far greater share of their own defence burden. As a result, the European Union now finds itself confronting a question that would have seemed alarmist only a few years ago: is Europe genuinely prepared for a major war?

For decades, European stability rested on three pillars—economic interdependence, diplomatic engagement, and the security umbrella provided by NATO and the United States. Integration was viewed not merely as an economic project but as a peace strategy. The expansion of the European Union, the creation of a single market, and the steady development of transatlantic institutions were all designed to make large-scale war on the continent nearly impossible. That assumption has been shaken. The invasion of Ukraine shattered long-standing beliefs that territorial conquest in Europe was a relic of history.

Today, Brussels operates with a heightened sense of urgency. Military planners, policymakers, and defence officials are working at an accelerated pace to strengthen deterrence, modernise armed forces, and reinforce industrial capacity. The debate is no longer theoretical. It is rooted in ongoing war, rising tensions, and increasingly explicit warnings from political and military leaders.

A Strategic Wake-Up Call

The war in Ukraine served as a brutal reminder that high-intensity conventional warfare remains possible in Europe. Beyond the humanitarian catastrophe and economic shockwaves, the conflict exposed structural weaknesses within Europe’s defence architecture. Many EU member states had significantly reduced defence spending after the Cold War, prioritising social programs and economic growth. Military stockpiles were limited, industrial production lines were slow, and cross-border coordination was often cumbersome.

Compounding this challenge is a shifting transatlantic dynamic. Recent American strategic documents and political rhetoric suggest that Washington expects Europe to assume greater responsibility for its own conventional defence. European policymakers interpret this as both a warning and an opportunity: a warning that reliance on the United States may no longer be unconditional, and an opportunity to pursue greater strategic autonomy.

In December, EU leaders approved a €90 billion loan package aimed at sustaining support for Ukraine. Meanwhile, European Commission President Ursula von der Leyen unveiled new defence initiatives designed to strengthen deterrence capacity by 2030. These measures reflect an understanding that European security can no longer be outsourced.

The rhetoric from Moscow has further intensified the atmosphere. On 2 December, Vladimir Putin warned that Russia was prepared to continue fighting and suggested that future negotiations might not be possible under certain conditions. Around the same period, NATO Secretary General Mark Rutte cautioned that NATO territory could become a target within five years. Germany’s defence minister Boris Pistorius added to the concern by remarking that Europe might have already experienced its “last summer of peace.”

Such statements, once dismissed as alarmist, are now taken seriously across defence circles.

Public Opinion: A Different Reality

Despite mounting political urgency, public sentiment across Europe appears more cautious. Surveys indicate a significant gap between government preparations and citizens’ willingness to personally engage in armed defence. A large-scale poll conducted by Euronews asked respondents whether they would fight to defend EU borders. Approximately three-quarters answered negatively, with only a minority expressing readiness to take up arms.

However, attitudes vary geographically. Countries bordering Russia or Belarus demonstrate markedly higher levels of concern. In Poland, Lithuania, and Denmark, more than half of respondents identify Russian military aggression as a primary threat. In these regions, the war in Ukraine is not viewed as distant but as a direct warning.

Across Europe more broadly, armed conflict now ranks among the top public concerns, alongside inflation, energy security, and migration. The psychological shift is profound. War preparedness has re-entered mainstream political discourse.

Eastern Europe at the Forefront

While all EU member states acknowledge rising risks, countries in Eastern and Northern Europe have taken the most visible steps to prepare their populations. Governments in Lithuania, Latvia, Estonia, Poland, Finland, and Sweden have adopted a comprehensive approach that combines military investment with civil resilience.

Lithuania has worked with Latvia to strengthen border defences, including the restoration of wetlands as natural barriers and the development of advanced surveillance infrastructure. Public awareness campaigns inform citizens about emergency procedures, shelter locations, and evacuation routes.

Latvia has introduced mandatory national defence education in schools, ensuring that younger generations understand both civic responsibilities and crisis response measures. Poland has constructed physical barriers along its border with Belarus and expanded security education programs, with some schools incorporating firearm safety training.

Finland, Estonia, and Sweden have revived Cold War-era civil defence practices. Sweden distributed updated “If Crisis or War Comes” brochures to households nationwide in 2025, outlining guidance on food storage, communication disruptions, and emergency response. Online search data indicates growing public interest in practical preparedness topics such as shelter locations and evacuation planning.

These initiatives reflect a broader recognition: deterrence depends not only on military hardware but also on societal resilience.

Brussels’ Coordinated Response

At the EU level, coordination has intensified dramatically. European defence spending exceeded €300 billion in 2024, marking a significant increase compared to pre-war levels. Under the proposed 2028–2034 EU budget framework, an additional €131 billion has been earmarked for aerospace and defence—five times the allocation of the previous cycle.

Central to this effort is the Readiness 2030 roadmap, endorsed by all 27 member states. The initiative aims to ensure that troops and equipment can move freely across EU borders within three days during peacetime and within six hours in emergencies. To achieve this, Brussels is working to remove bureaucratic obstacles through a “Military Schengen” system, simplifying cross-border transport for armed forces.

Approximately 500 critical infrastructure points—bridges, tunnels, ports, and railways—are being identified for upgrades to accommodate heavy military equipment. The estimated cost ranges from €70 to €100 billion, financed through national budgets and EU programs such as the Connecting Europe Facility.

This logistical transformation may prove as important as increased spending. Without rapid mobility, deterrence loses credibility.

ReArm Europe: Industrial Transformation

In 2025, the European Commission launched ReArm Europe, a coordination platform designed to address fragmentation within Europe’s defence industry. Historically, European nations have developed separate weapons systems with limited interoperability. This duplication increased costs and slowed procurement.

ReArm Europe introduces two major financial tools:

1. The European Defence Industry Programme (EDIP), allocating €1.5 billion for joint research and production projects involving at least three EU countries.
2. The Strategic Armament Financing Envelope (SAFE), a €150 billion loan facility enabling joint weapons procurement at reduced cost and accelerated timelines.

By pooling demand, member states can negotiate better contracts, expand production capacity, and ensure compatibility across systems. Early demand for SAFE has been substantial, with hundreds of projects submitted covering air defence, ammunition, missile systems, drones, and maritime capabilities.

The American Factor

Pressure from Washington has been a decisive catalyst. Recent U.S. national security strategies emphasise an “America First” orientation and portray Europe as a partner that must increase its defence contributions. Former President Donald Trump repeatedly criticised European defence spending levels, arguing that NATO allies should meet or exceed agreed targets.

At the 2025 NATO summit in The Hague, allies committed to aiming for defence expenditures equivalent to 5% of GDP by 2035. Most European nations remain below that threshold, though spending has risen steadily since 2022.

American strategic documents also hint at a long-term interest in stabilising relations with Russia, raising concerns in Brussels that European security guarantees could become more conditional. This uncertainty has strengthened arguments for greater European strategic autonomy.

European leaders have responded assertively. Officials such as Valdis Dombrovskis, António Costa, and Kaja Kallas have emphasised that allies must respect each other’s democratic decisions and that Europe intends to shape its own security future.

Structural Constraints

Despite increased budgets and political determination, structural obstacles remain significant. Europe’s defence industry has struggled with fragmented supply chains, slow procurement processes, and regulatory complexity. Decades of underinvestment cannot be reversed instantly.

Defence Industrial Readiness assessments reveal production bottlenecks and incompatibilities between national systems. Brussels has begun accelerating regulatory reforms and simplifying funding rules, but scaling production to meet modern wartime demand remains a formidable challenge.

Moreover, public reluctance to engage directly in military service could complicate mobilisation strategies. Democracies must balance preparedness with public consent, ensuring transparency and accountability.

The Road Ahead

Europe’s current trajectory reflects a fundamental shift in mindset. Defence is no longer treated as a secondary policy area but as a central strategic priority. Investments in mobility, industrial capacity, joint procurement, and civil preparedness signal a long-term transformation.

Yet the timeline is compressed. Policymakers must modernise defence industries, sustain support for Ukraine, maintain unity among 27 member states, and navigate a changing transatlantic relationship—all while deterring potential aggression.

The essential question has evolved. Europe is no longer debating whether it should prepare for war. It is racing to determine whether it can build sufficient readiness before geopolitical pressures intensify further.

In this environment, preparedness serves a dual purpose: strengthening deterrence while preserving peace. The paradox of European defence policy in 2026 is that the continent is preparing more seriously for conflict precisely in order to prevent one.
