Europe struggles to counter Russia's hybrid warfare campaign, defence officials warn
Europe is reacting rather than anticipating.
Mark
So when they say Europe is losing this battle, what exactly are they losing? Is there a scoreboard?
Mimi
Not a traditional one. It's more that Russia keeps probing—sabotaging infrastructure, cutting cables, disrupting communications—and Europe keeps responding after the fact rather than preventing it. Each incident is small enough to deny, but they add up.
Luke
Right, but we should be careful here. The reporting says officials warn about this, but how many actual sabotage incidents have been confirmed and attributed to Russia? The source material doesn't give us numbers.
Mimi
That's fair. The concern is partly about what's happening and partly about what officials fear could happen if Russia escalates beyond these hybrid tactics.
Mark
And the US is pushing NATO to prepare. Prepare for what, exactly? A full invasion?
Mimi
More like a sustained conflict. The worry is that Europe doesn't have the industrial base or military stockpiles to fight a long war with Russia. They could handle a crisis, but not years of attrition.
Luke
Again, though—we're hearing this from defence officials. Are there independent assessments of European military capacity? Or are we taking the officials' word that the gap is as large as they're suggesting?
Mimi
The officials are the primary source here. They're the ones with access to the actual capability assessments. But you're right that we're not seeing independent verification in this reporting.
Mark
So what does "prepare" mean in practical terms? What are NATO allies actually supposed to do?
Mimi
Increase military spending, build up stockpiles, harden critical infrastructure against sabotage, improve intelligence sharing. The basics of deterrence.
Luke
And is that happening? Is there evidence that NATO members are actually moving in that direction, or is this just a warning that hasn't yet changed behaviour?
Mimi
The reporting suggests it's still mostly warnings. The US is urging allies to prepare, which implies they haven't fully done so yet.

- Russia is systematically targeting European power grids, communications networks, and undersea cables — each strike designed to stay just below the threshold that would compel a unified NATO response.
- The attribution problem is Russia's greatest weapon: when sabotage is indistinguishable from accident, the political and legal bar for retaliation remains too high to clear.
- European defence leaders are confronting a structural crisis — not a failure of resolve, but a deficit of industrial capacity, military stockpiles, and defensive infrastructure that years of underspending have produced.
- The United States is pressing NATO allies to act now, in peacetime, warning that waiting for a full-scale crisis before building deterrence capacity is a strategy that has already begun to fail.
- Europe is reacting where it must anticipate — and Russia, watching closely, is refining its tactics with each probe that goes unanswered.
Across European capitals, a quiet reckoning is underway: the continent finds itself engaged in a war it has not formally declared and is not fully prepared to fight. Russia's hybrid campaign — sabotage, covert disruption, infrastructure attacks calibrated to evade collective response — is exposing structural gaps in NATO's deterrence architecture that political will alone cannot close. The warning from defence officials is not one of imminent invasion, but of slow erosion: a security order being worn down at its edges, incident by deniable incident, while the mechanisms for response remain incomplete.
European defence officials are sounding an alarm that is growing harder to dismiss: the continent is losing ground in a conflict that bears little resemblance to traditional war. Russia's hybrid campaign — infrastructure sabotage, covert operations, intelligence pressure — is advancing steadily while European governments struggle to formulate an effective response. The assessment from those inside the defence establishment is unsparing: current deterrence is not working.
What makes the threat so difficult to counter is its deliberate ambiguity. Attacks are engineered to be deniable, calibrated to remain below the threshold that would trigger collective NATO action, yet cumulative in their corrosive effect. A disrupted power grid, a severed undersea cable, a compromised communications network — each incident exists in the grey zone between peacetime incident and act of war, leaving European officials with suspicion but rarely the certainty required to respond.
The structural concern runs deeper than any single attack. Europe, defence leaders acknowledge, lacks the industrial base, military stockpiles, and defensive infrastructure to sustain a prolonged war of attrition should Russia escalate beyond hybrid tactics. This is not a crisis of political will — it is a crisis of capacity built over decades of underinvestment that cannot be reversed quickly.
The United States has begun pressing allies to treat preparation as an immediate obligation rather than a future contingency. The message is direct: the window for building deterrence in peacetime is open now, and it will not remain so indefinitely. Yet coordinating defensive measures across NATO's diverse membership requires political cohesion that has been slow to emerge, and developing the strategies needed to operate in the grey zone remains work most European nations have not yet seriously begun.
Defence officials are not without clarity about what is happening. The problem is the distance between diagnosis and remedy. Russia is learning, adapting, and pushing further with each cycle. Unless European governments invest substantially, coordinate more deliberately, and establish credible consequences for hybrid aggression, the erosion will continue — quiet, cumulative, and without the dramatic threshold-crossing moment that might finally compel a unified answer.
Defence officials across Europe are sounding an alarm that has grown harder to ignore: the continent is losing ground in a conflict that doesn't look like traditional war. Russia is waging what strategists call hybrid warfare—sabotage of critical infrastructure, covert operations, intelligence campaigns—and European governments are struggling to mount an effective response.
The assessment is blunt. Officials acknowledge that current deterrence measures are not working. Russia continues to probe European vulnerabilities, targeting everything from power grids to communications networks to undersea cables. The attacks are designed to be deniable, difficult to attribute with certainty, and hard to respond to through conventional military means. Each incident is calibrated to stay below the threshold that would trigger a unified NATO response, yet the cumulative effect is corrosive.
The deeper concern, articulated by defence leaders across multiple European capitals, is structural. Europe lacks the capacity to sustain a prolonged war of attrition with Russia. This is not a question of will or political commitment. It is a question of industrial base, military stockpiles, and defensive infrastructure. If Russia escalates beyond hybrid tactics into direct military confrontation, European nations would face a grinding conflict they are not equipped to endure. The gap between current military spending and what would be required to match Russian capabilities remains substantial.
The United States has begun pushing NATO allies to take the threat more seriously. American officials are urging European governments to prepare defensive measures and strengthen their deterrence posture. The message is clear: waiting for a crisis to arrive is no longer a viable strategy. Preparation must happen now, in peacetime, when there is still room to build capacity and coordinate response.
What makes hybrid warfare particularly difficult to counter is its ambiguity. A power outage could be equipment failure or sabotage. A communications disruption could be technical malfunction or attack. The attribution problem means that even when European officials suspect Russian involvement, the political and legal threshold for response remains high. This creates space for Russia to operate with relative impunity, testing defences and probing for weaknesses without facing consequences proportionate to the damage inflicted.
European defence establishments are not blind to the problem. They understand the threat. But understanding and responding are different things. Building the industrial capacity to sustain conflict takes years. Coordinating defensive measures across NATO's diverse member states requires political will that has been slow to materialize. And deterring an adversary who operates in the grey zone between peace and war requires capabilities and strategies that most European nations have not yet developed.
The consensus among defence officials is that the current trajectory is unsustainable. Russia is learning what works, refining its tactics, and pushing further. Europe is reacting rather than anticipating. Unless that dynamic shifts—unless European governments invest significantly in defensive capacity, coordinate more effectively, and develop clearer red lines and consequences—the hybrid war will continue to erode European security without ever crossing into the kind of open conflict that would trigger a unified response.
