Across the European Union, a profound psychological shift is underway. What was once dismissed as alarmism is now treated as planning for the inevitable. Budgets once reserved for welfare and green transitions are being redirected toward ammunition, air defence, and industrial rearmament. The €90 billion pledged to Ukraine is no longer seen as charity, but as payment on Europe’s own security bill, made in advance. Von der Leyen’s 2030 defence ambitions, once technocratic talking points, now resemble an emergency blueprint drafted in slow motion.

Yet beneath the new urgency lies a deeper anxiety: Europe is trying to prepare for war without admitting it to its own citizens. Leaders speak of “deterrence” and “readiness,” while defence ministers warn that the window to act is closing fast. Between fears of Russian escalation and doubts about future US guarantees, Brussels is not choosing war—but it is finally acting as if war might choose it.
