The New Era of European Defence
In today’s world, Europe is undergoing a dramatic shift in its approach to security. What was once a topic that Europe avoided—rearming—is now at the forefront of its priorities. Geopolitics has moved from being an abstract concept discussed by diplomats and think tanks to an urgent reality that shapes budgets, economies, and national identities. After years of treating security as secondary or discretionary, defence has become a central concern for European nations.
The numbers speak volumes. In 2024, military spending in Europe surged by 17 percent, reaching an impressive $693 billion. This marked a record increase, with almost all European countries raising their defence budgets, except for one small republic. Military spending is now at its highest level since the end of the Cold War. Within the European Union alone, defence expenditure reached €343 billion in 2024, accounting for about 1.9 percent of GDP. Analysts predict this will rise to €381 billion in 2025. Over just three years, EU member states have increased their real-term defence spending by more than 30 percent.
This rearmament is not uniform across the continent. Countries located near Russia or other conflict zones have been increasing their spending the most aggressively. Poland, for example, raised its military expenditure from 2.7 percent of GDP in 2022 to over 4.2 percent in 2024, with a target of 4.7 percent in 2025. Germany, supported by a special defence fund, boosted its military budget by more than 28 percent in 2024 and is leading the Western European effort. Meanwhile, countries in southern Europe are more cautious. Spain, for instance, faces political pressure to focus on social spending rather than military investment. This disparity highlights the varying degrees of strategic urgency across the continent.
A major shift occurred in mid-2025 when NATO members agreed on a new goal: to allocate 5 percent of GDP to defence and security by 2035. This includes 3.5 percent for core military capabilities such as troops, equipment, and readiness, and an additional 1.5 percent for infrastructure, cyber defence, and military mobility. While many analysts question the feasibility of this goal, especially for smaller economies, the message is clear: Europe is moving from token increases to structural reform.
Beyond Economics: A Shift in Strategic Thinking
The reasons behind this shift go beyond economic considerations. The full-scale invasion of Ukraine by Russia shattered the illusion that Europe could rely indefinitely on geography, diplomacy, or American military power. Security threats are growing not only on the periphery but also in areas like supply chains, energy, cyberspace, and critical technologies. The assumption that the United States would continue to subsidize European defence is fading. In cities like Brussels, Berlin, Paris, and Warsaw, the discussion now centers on credible deterrence and strategic autonomy.
However, increased funding does not automatically translate into greater security. Capability matters. Many European nations are investing heavily in drones, missile defences, fighter jets, and naval vessels. Denmark recently ordered up to 16 F-35s, while Germany invested $10 billion in drone production. But hardware is only part of the equation. Resilience, logistics, mobility, and industrial capacity must also be strengthened. Shortfalls in stockpiles, maintenance, and interoperability still undermine deterrence efforts.
Political Tensions and Public Awareness
The rising defence budgets are also creating political tensions. Balancing military priorities with welfare obligations is a complex challenge. In some countries, defence spending may soon match or exceed investments in education or healthcare. This could lead to public dissatisfaction, especially among voters already struggling with inflation, high prices, and stagnant incomes. If rearmament is seen as harming living standards, the public support for it may weaken. Transparency and accountability are essential to maintain trust.
At the same time, defence policy is shaping the identity of Europe. The debate is no longer just about how much to spend, but whether to spend at all. Should Europe aim for global power projection or focus on regional defence? How should it address emerging threats like cyberwarfare and robotics? These strategic questions, once discussed in the shadows, are now gaining clarity and prominence.
Public awareness and consent are crucial. Rearmament cannot succeed if people do not understand its purpose. Governments must be open about the threats Europe faces and explain how increased defence spending enhances security. It is not about returning to Cold War-era thinking, but about developing a new, plausible form of deterrence in an age where military, economic, and digital strength are deeply intertwined.
Key Steps for a Successful Transition
To ensure that this shift strengthens rather than destabilizes Europe, several steps must be taken:
-
Phased and Gradual Expenditure: Sudden increases in military spending can cause shocks and political backlash. Incremental targets tied to measurable capability improvements will be more sustainable and defensible.
-
Coordination Among Nations: Countries must align procurement pipelines, research institutions, and defence infrastructure. Cooperative programs can reduce duplication and build confidence.
-
Preserving Civilian Priorities: Social programs should not be sacrificed for defence budgets. A balanced approach that considers both security and social cohesion is necessary.
-
Broad Definition of Security: Security must encompass cyber defence, energy resilience, disaster preparedness, and key infrastructure.
-
Tracking and Assessing Progress: Independent oversight, parliamentary scrutiny, and public participation can help ensure that spending delivers tangible results, not waste or corruption.
The Future of European Defence
Europe’s rearmament is no longer a theoretical debate; it is a reality. The question now is whether it will be strategic or reactive, coherent or ad hoc, democratic or closed. If done well, it can lay the foundation for long-term stability and strength. If mishandled, it could lead to resentment, inefficiency, and unintended consequences.
The stakes are high. A secure Europe is not just a military goal—it is a social and political imperative. In an era of hybrid threats, fluid alliances, and fragile public trust, the way Europe builds its defence strategy will shape its future.
