Europe’s strategic environment is entering one of its most dramatic transformations since the end of World War II. For nearly eighty years, the idea of a large-scale war on the continent existed largely as an abstract concern. That assumption has now been forcefully overturned. Russia’s full invasion of Ukraine has compelled the European Union to reexamine the foundations of its security model—one long built on diplomacy, economic interdependence, and a deep reliance on American military protection. In Brussels, the focus has shifted decisively from routine governance to urgent defense planning, as policymakers and military officials scramble to strengthen Europe’s readiness in the face of mounting external threats. The long-enjoyed “peace dividend” has given way to an era defined by rearmament, industrial mobilization, and societal preparedness.
Several forces are driving this accelerated shift. The war in Ukraine has decisively dispelled the belief that high-intensity conventional conflict belonged to history. At the same time, political signals from Washington suggest a recalibration of U.S. priorities, with American leaders increasingly emphasizing that Europe must shoulder responsibility for its own defense. This dual pressure—an aggressive Russia on one flank and uncertainty over sustained U.S. backing on the other—has pushed European leaders into action at unprecedented speed. Among the most notable responses are a €90 billion financial support package for Ukraine and a sweeping set of defense initiatives advanced by European Commission President Ursula von der Leyen, all aimed at strengthening Europe’s deterrence posture before the decade’s end.
Statements from key political and military figures have reinforced the seriousness of the moment. In late 2025, Russian President Vladimir Putin signaled readiness for a prolonged and total confrontation, implying that diplomatic off-ramps may be narrowing. NATO Secretary General Mark Rutte echoed these concerns, warning that Russia’s strategic ambitions could extend to NATO territory within the next five to ten years. Germany’s Defense Minister, Boris Pistorius, added to the sense of urgency by suggesting Europe may already have experienced its “final summer of peace.” These remarks are more than rhetoric—they are shaping budget decisions, defense planning, and even civilian life in states closest to potential conflict zones.
Public opinion, however, tells a more complicated story. A Euronews survey of nearly 10,000 respondents across the EU revealed a striking disconnect between government preparedness and civilian willingness to fight. Roughly three-quarters of participants said they would not take up arms to defend EU borders, while fewer than one in five expressed readiness to do so. Yet this reluctance is not uniform. In countries geographically closer to Russia, threat perception is far more pronounced. In Poland, Lithuania, and Denmark, majorities identify Russian military pressure as the leading national security concern, surpassing economic instability and energy shortages. These nations are responding by placing a strong emphasis on civilian resilience and defense awareness.
