For decades, the dream of a “United States of Europe” has been the North Star for federalists in Brussels. They marched under various banners, Communities, Unions, and Councils, always pushing for a singular, synchronized leap toward integration. However, the reality of 2026 suggests a different path. We are witnessing the birth of what some playfully call the “European Onion”: a multi-layered, pragmatic model of continental cooperation.

Beyond the One-Size-Fits-Old Model
The traditional EU approach, where every member must move at the same speed, is increasingly hitting a wall. In a geopolitical climate that demands rapid responses, the “slowest member” rule has become a liability. Whether it is military autonomy, trade policy, or technological independence, Europe can no longer afford to wait for total consensus.
The “Onion” metaphor, popularized by Belgian Prime Minister Bart De Wever, envisions a Europe of concentric circles:
- The Core (The Kernel): A pioneering group of “heavy hitters”, like the E6: France, Germany, Italy, the Netherlands, Poland, and Spain, pushing for deeper economic and military integration.
- The Inner Layers: Countries participating in the Single Market and Schengen but perhaps opting out of certain federalist deeper dives.
- The Outer Layers: Strategic partners like Ukraine or even the UK, who require a functional relationship with the bloc without immediately meeting every rigid bureaucratic standard.
Pragmatic Federalism in Action
We are already seeing this “variable geometry” take shape. When financial aid or security measures are blocked by a small minority, “coalitions of the willing” simply move forward. This is not about creating second-class citizens; it is about pragmatic federalism.
History shows that where pioneers lead, others eventually follow. The Euro and the Schengen Area both started as smaller projects before becoming continental standards. By allowing a vanguard to forge ahead, we prevent the entire European project from ending in tears due to inertia.
If the current structure of the EU is too rigid for the modern world, we must be bold enough to peel back the layers and redesign it. A multi-speed Europe is not a sign of weakness; it is a strategy for survival.
