It’s hard to believe, but we’ve now marked four full years since Russia’s full-scale invasion of Ukraine turned Europe’s security landscape upside down. I remember watching the news in late February 2022, feeling that familiar chill when history shifts gears suddenly. Back then, few predicted the war would drag on this long, reshaping alliances, budgets, and even the very idea of what European defense could look like. Yet here we are in 2026, and the conversation has evolved dramatically—from quiet concerns about reliance on Washington to open calls for Europe to stand on its own two feet militarily. The question hanging in the air feels heavier than ever: after all this time, is Europe actually ready to build its own army?
I’ve followed these debates closely over the years, and something strikes me as particularly fascinating. The war didn’t just expose vulnerabilities; it cracked open a long-dormant discussion about strategic autonomy. For decades, the notion of a unified European force was more theoretical than practical, often dismissed as unrealistic or even divisive. Now, though? The tone has changed. Leaders, experts, and ordinary citizens alike are asking whether the current setup—fragmented national militaries loosely coordinated through NATO—can hold up in an increasingly unpredictable world.
The Push for a Unified European Defense Force
The idea isn’t new, but its urgency certainly is. Proposals for some form of European army have surfaced repeatedly since the early days of post-World War II integration. What feels different today is the context: a grinding war on the continent’s doorstep, combined with uncertainty across the Atlantic. Many observers point out that Europe’s defense efforts remain plagued by duplication, incompatible equipment, and inefficient spending. Fixing that through deeper cooperation seems logical on paper, yet the path forward remains anything but straightforward.
One prominent voice recently suggested the EU should aim for a standing force of around 100,000 troops capable of operating cohesively. The argument is straightforward: Europe needs to be able to act decisively as Europe, not just as a collection of nations hoping allies will fill the gaps. It’s a bold vision, one that resonates with those worried about over-reliance on external partners. But bold doesn’t always mean feasible.
Historical Attempts and Why They Faltered
Let’s step back for a moment. The dream of a joint European military dates back to the 1950s, when the continent was still rebuilding from devastation and facing a clear Soviet threat. Early proposals envisioned integrated forces to balance German rearmament while fostering unity. Those plans collapsed under political resistance—national sovereignty proved too precious to surrender so soon after the war.
Over the following decades, similar ideas resurfaced periodically, often tied to moments of crisis. Each time, though, the same obstacles emerged: differing strategic priorities, varying threat perceptions across member states, and the comforting presence of NATO’s collective defense umbrella. Why risk fracturing unity when the transatlantic alliance provided security at a relatively low political cost? In hindsight, that bargain made sense for a long time. But bargains can expire.
The real challenge isn’t money—it’s political will and the willingness to share sovereignty in ways that matter most.

I’ve always thought that quote captures the heart of the matter. Cash can be allocated, equipment standardized, even troops trained together. But asking nations to place core defense decisions under supranational command? That’s where the rubber meets the road—and often skids.
Current Realities: Fragmentation and Inefficiencies
Europe’s militaries today are, frankly, a patchwork. Different calibers of ammunition, incompatible communication systems, overlapping procurement programs—it’s a recipe for confusion in a crisis. Analysts have pointed out for years that this fragmentation wastes billions annually. When you add up the redundancies, the picture becomes stark: Europe spends a lot but gets less bang for its buck than it should.
- Multiple types of fighter jets requiring separate maintenance chains
- Duplicated research into similar technologies across borders
- Limited joint training that doesn’t fully simulate multinational operations
- National industries competing rather than collaborating on key projects
These aren’t minor inconveniences. In a high-intensity conflict, interoperability can mean the difference between success and failure. Recent conflicts have shown how quickly modern warfare consumes resources—ammunition, spare parts, intelligence sharing—and Europe’s current setup struggles to keep pace.
Some progress has been made. Joint procurement initiatives for ammunition and air defense systems represent steps forward. Small budgets for collaborative projects signal intent. Yet many wonder if these incremental moves are enough when the threats are growing more sophisticated and immediate.
Public Opinion: A Surprising Shift Toward Unity
Here’s where things get interesting. Contrary to what skeptics might expect, Europeans appear increasingly open to deeper defense integration. Polls over recent years show steady climbs in support for a common security and defense policy. In some surveys, backing exceeds 80 percent in certain countries—a remarkable figure considering historical sensitivities around national militaries.
Even questions about a regional army that incorporates national forces garner majority approval in places like Lithuania, Germany, Spain, and others. It’s not universal, of course—support varies by country and demographic—but the trend is clear. People feel vulnerable, and they’re looking for solutions beyond the status quo.
In my view, this shift reflects a deeper psychological change. The war in Ukraine shattered the post-Cold War illusion of perpetual peace in Europe. Citizens now see tangible risks, and abstract debates about sovereignty feel less urgent than concrete protection. Whether that translates into political action remains to be seen, but the electoral math looks increasingly favorable for leaders willing to push integration.
The NATO Dilemma: Strengthening the European Pillar or Going Separate?
One of the sharpest divides in this discussion concerns NATO. Many leaders insist that any European effort should strengthen the alliance’s European pillar rather than create a parallel structure. The reasoning makes sense on the surface: most EU countries are already NATO members, so why duplicate command structures, planning processes, or capabilities?
Others counter that relying indefinitely on external leadership carries risks—especially when transatlantic relations face strains. Building European capacity within NATO could, in theory, address both concerns. Yet critics argue this approach lacks ambition. Without genuine integration, Europe remains a junior partner, unable to act independently if needed.
We need to boost our defense industry and increase European capabilities—used nationally and in NATO, not as a separate EU army.

That perspective resonates in several capitals, particularly those closest to traditional Atlantic ties. But others see it as perpetuating dependency at a time when self-reliance matters more than ever.
Challenges Ahead: Decision-Making, Command, and Sovereignty
Even if political will solidifies, practical hurdles loom large. Who decides when a European force deploys? How do you create command structures that respect national sensitivities while ensuring efficiency? These questions have bedeviled previous attempts at integration, and they haven’t gotten easier.
Then there’s the sovereignty issue. Nations guard their militaries jealously—symbols of independence as much as instruments of policy. Asking governments to cede control over core defense functions requires trust that’s often in short supply. Add differing threat perceptions—Russia looms larger in the east than in the south—and consensus becomes elusive.
- Establish clear decision-making mechanisms for rapid response
- Develop interoperable command and control systems
- Harmonize training and doctrine across participating nations
- Align procurement strategies to eliminate wasteful duplication
- Build public and political consensus on shared burdens
These steps sound straightforward, but executing them demands years of sustained effort. History suggests Europe excels at ambitious declarations but sometimes stumbles on implementation.
Economic and Industrial Dimensions
Defense isn’t just about troops—it’s also about industry. Europe’s defense sector remains fragmented, with national champions competing rather than collaborating. Recent initiatives aim to change that through joint funding and procurement targets. The goal: make European industry more competitive while reducing reliance on external suppliers.
Some countries push hard for this approach, arguing that integration starts with the industrial base. Others remain cautious, fearing it could disadvantage domestic firms. Yet the logic is compelling: a stronger, more unified industry could deliver capabilities faster and cheaper while creating jobs and innovation.
Perhaps the most intriguing aspect is how economic arguments now intertwine with security ones. In uncertain times, investing in defense isn’t just about protection—it’s about competitiveness and resilience too.
Looking Forward: Realistic Pathways in a Changing World
So where does this leave us? A full-fledged, sovereign European army seems unlikely in the near term—too many obstacles, too much resistance. But that doesn’t mean stasis. Incremental progress—more joint projects, better coordination, increased spending—could gradually build the foundation for something more ambitious.
I’ve come to believe the most probable path involves strengthening NATO’s European component while carving out greater autonomy in specific areas. Hybrid threats, cyber defense, rapid response forces—these lend themselves to European leadership without directly challenging the alliance’s core.
Ultimately, readiness isn’t just about hardware or headcount. It’s about mindset. The war in Ukraine forced Europe to confront uncomfortable truths. Whether that leads to genuine transformation or merely louder rhetoric remains an open question. But the conversation itself marks progress. For the first time in generations, Europeans are seriously asking what it would take to defend themselves—truly, collectively, independently if necessary. And that, perhaps, is the most important shift of all.
The coming years will test whether this momentum sustains itself or fades as other crises compete for attention. One thing feels certain: the status quo no longer feels sustainable. Europe faces a choice—adapt together or risk being caught unprepared when the next storm arrives. Personally, I hope we choose adaptation. The alternative is simply too costly to contemplate.
