After Russia’s full-scale invasion of Ukraine and mounting pressure from Washington, the European Union is confronting a reality that once seemed distant: it must be prepared to defend itself. For decades, Europe relied on diplomacy, economic ties, and strong U.S. security guarantees. Now, with the war dragging on and transatlantic trust under strain, Brussels is accelerating efforts to strengthen its military readiness and industrial capacity.

European leaders have committed billions toward Ukraine and significantly increased defense budgets at home. New initiatives aim to streamline troop movement across borders, upgrade critical infrastructure, and coordinate weapons procurement under programs like Readiness 2030 and ReArm Europe. Defense spending has surpassed €300 billion, with long-term plans to invest even more in aerospace, missile systems, and logistics. Yet officials acknowledge that decades of underinvestment and fragmented defense industries cannot be fixed overnight.

Public opinion tells a more complicated story. While Eastern European countries closest to Russia are expanding civil defense programs and running preparedness drills, broader surveys show many Europeans remain reluctant about direct military involvement. The gap between political urgency and public readiness highlights the social challenge facing EU governments as they prepare for worst-case scenarios.

At the heart of the debate is speed. Europe must modernize its forces, sustain support for Ukraine, and respond to increasingly direct warnings from NATO—all while navigating economic pressures and political divisions. The question in Brussels is no longer whether Europe should act, but whether it can move quickly enough to meet a shifting and uncertain security landscape.
