Russia’s full-scale invasion of Ukraine in 2022 has fundamentally altered Europe’s security outlook. Once defined largely by political and economic cooperation under post-Cold War peace, the continent is now re-evaluating its approach to defence, deterrence, and preparedness.
European policymakers and strategists are articulating a new consensus: Europe’s security cannot be taken for granted. This emerging perspective has manifested not only in policy shifts and budgetary commitments, but in an unmistakable tone of urgency from European leaders themselves.
During the last NATO summit on June 24–25 last year, French President Emmanuel Macron, articulating this shift, summed up the impulse behind Europe’s militarisation: “We are all rearming ourselves – because this threat is at our borders.” Macron identified a long‑term Russian threat as the driving factor for increased defence investment, asserting that the war in Ukraine ‘very clearly allowed us to identify this long‑term threat.’
Likewise, NATO Secretary General Mark Rutte has repeatedly reframed the security challenge, stressing preparedness and deterrence. At one forum, he cautioned allies that Russia’s expanding military capabilities render complacency dangerous, uttering: “We are all on the Eastern flank now,” and prioritising the speed of modern weapons that can bridge the distances between capitals in minutes.
The broadest expression of these changing priorities emerged at the last NATO summit in The Hague, where member nations agreed to raise defence spending targets to 5 percent of GDP by 2035 – more than doubling the historical benchmark of 2 percent. Among others, the U.S. President Donald Trump says: “I’ve been asking them to go up to 5 percent for a number of years, and they’re going up to 5 percent.”
Taken together, these official statements reflect a clear evolution in European strategic thinking. Defence is no longer a peripheral line item in national budgets. It is becoming central to how nations conceive of their security and autonomy.
However, this shift is not merely assessable; it is conceptual. The notion of deterrence has expanded beyond NATO’s traditional Article 5 collective defence guarantee into a broader geopolitical posture. European capitals are signalling that deterrence now involves not just preparedness but a degree of proactive readiness. As NATO chief himself has said: “We are safe now, we might not be safe in five years”.
This shift has had material consequences. European defence spending has reached record levels in recent years, with countries such as Germany significantly increasing their military expenses. But as the newspaper The Guardian reports, increasing defence budgets does not come without compromise. Analysts like Sebastian Mang, senior policy officer at the New Economics Foundation, note that “Europe’s public finance debate has never been about what we can afford, but what governments choose to prioritise.” In other words, greater investment in tanks and missiles inevitably competes with spending on climate mitigation, healthcare, and education.
Public opinion across Europe is also shifting, but unevenly. An article titled, Europeans back higher defence spending amid Russia threat… published by The Guardian reveals strong support for higher military spending in some countries. For example, around 70 percent in Poland and Denmark, while other countries show softer or divided views on militarisation and even resistance to measures like mandatory service. These variations highlight that Europeans are grappling with the balance between security concerns and domestic priorities.
Meanwhile, Russia insists that NATO’s actions are not a provocation. Russian President Vladimir Putin has publicly stated: “We do not consider any rearmament by NATO to be a threat to the Russian Federation”, framing Western defence policy as irrelevant to Russia’s own security calculus, even as Moscow continues to modernise its forces and presses its military campaign in Ukraine.
This dynamic feeds into a broader dilemma: the shift toward heightened military readiness is both a response to real strategic concerns and a potential source of increased tension. European leaders argue that greater defence capability is indispensable – not just to deter a conventional Russian attack, but also to respond to hybrid threats including cyberattacks, sabotage, and information warfare.
At the same time, there is a recognition among strategic thinkers that security cannot be ensured by military power alone. Comprehensive defence involves diplomacy, economic resilience, and societal cohesion. However, as public discourse normalises large defence expenditures and prioritises readiness, there is a risk that the language of deterrence begins to overshadow other policy domains.
Taken together, these dynamics suggest that Europe’s current trajectory shows that the continent is no longer content to treat security as a peripheral concern. So its current condition can thus be seen as a moment of silent preparation, one in which war has not been formally declared, yet the shadow of its possibility is slowly spreading across politics, policymaking, and the social psyche. This is certainly not the outcome of any single, sudden decision; rather, it represents the natural culmination of several years of sustained tension, deepening mistrust, and strategic rearrangement.
Whether this state of preparedness will remain confined to defensive vigilance or push the world toward a broader military polarisation remains an open question. What is clear, however, is that Europe is moving toward a new security reality – one in which the footprints of war may not be visible, but the quiet echoes of its possibility can be felt all around.
