In recent days, two seemingly unconnected events tell a unified story: Europe no longer inhabits a peaceful, uncontested continent—but an exposed, contested geopolitic frontier. In the North Sea, the Royal Navy tracked for hours the Russian vessel Yantar, a spy ship specializing in mapping undersea cables and critical infrastructure. Meanwhile, in Germany, the federal government approved a measure that allows the Bundeswehr to operate alongside police in neutralizing hostile drones in cases of hybrid threat. Two different fronts, one message: Moscow is testing our attention spans, our reaction time—and, above all, our willingness to defend ourselves. And Europe is finally beginning to respond.

The Yantar Lesson: the sea has become a frontline again

What was the Yantar doing at the edge of Britain’s waters? Hardly a goodwill tour. The ship is built for intelligence collection and, notably, for mapping undersea cables—those invisible lines that carry 97 % of global data traffic. If pipelines became vulnerable after the Nord Stream incident, undersea cables now represent the nervous system of the Western digital economy.

As Britain’s Defence Secretary John Healey declared:

“My message to Russia and to Putin is this: ‘We see you. We know what you’re doing. And if the Yantar travels south this week, we are ready.’”

That is precisely how a democracy must speak when an authoritarian regime approaches its critical infrastructure.

European defence cannot succeed without constant maritime surveillance, without frigates ready to deploy, and without the awareness that our security starts well beyond the dock of our own ports. In that sense, the British response is a model. A vigilant NATO is the leading deterrent to Putin’s adventurism.

Germany rediscovers internal security as part of collective defence

The other frontier is aerial/infrastructural. Berlin has approved legislation allowing the Bundeswehr to cooperate with police to shoot down dangerous drones. A decision that, until a few years ago, would have seemed politically unimaginable in post-1945 Germany.

But something has changed. Hybrid threats—hostile drones, interference in airspace, technological sabotage—do not respect formal borders. They demand swift, integrated, coordinated responses. The fact that the German government has recognized the need for military support to protect civilian infrastructure is a pivotal step. And it reveals a truth that many in Europe still struggle to admit: security is not just a military issue—it is national, industrial, economic. Without security there is no freedom, and without freedom there is no Europe.

The common thread: Europe must stop being a theatre and start being an actor

Putin continues to test our cohesion—from the war in Ukraine to disturbance operations in Northern seas. Therefore, the British and German episodes should not be read as isolated aberrations but as signs of a continental awakening.

• London guarding the North Sea.
• Berlin boosting its internal posture.
• The Baltic states investing in air defence.
• Poland ramping up like never before.
• Italy, despite its slower pace, still increasing its Alliance contribution.

This is the moment for a political leap: Europe must speak and act as a determined ally of NATO, not as a concerned spectator.

Ukraine: the ultimate test of our credibility

Everything converges on the most important theatre: Ukraine. For more than three years, Kyiv has resisted not merely the Russian army, but our own temptation to treat the war as “distant.” It is not. The Yantar near Scotland reminds us. Germany’s anti-drone units remind us. Pressure on Moldova, threats in the Balkans—they all remind us. War has returned to the European continent, whether we like it or not. And if Kyiv falls, do not delude yourself: Russian imperialism will turn its gaze swiftly beyond.

Supporting Ukraine—militarily, politically, financially—is not a gesture of generosity. It is an act of self-defence. The Ukrainian frontier is our frontier.

A new European doctrine for the decade of security

These days deliver a simple truth: European security requires decision, not ambiguity; it needs strength, not equidistance; it demands responsibility, not naïveté. We must:

• Invest steadily in defence;
• Strengthen maritime and aerial deterrence;
• Respond without hesitation to every Russian provocation in our skies and seas;
• Build a European defence that complements—rather than replicates—the NATO framework;
• Support Ukraine until victory.

We cannot afford to let the Russians act unchecked near our coasts or ignore hostile drones in our skies. Europe must show itself for what it is: a free continent determined to remain free. If the West truly intends to preserve its security order, this is the decade in which to choose: spectators or defenders of our own liberty. Russia has already chosen its path. It’s now our turn.
