## Introduction: Warsaw Sounds the Alarm Over a War Without a Declaration of War

### A document that says aloud what Europe has been whispering for months

On **June 16, 2026**, in **Luxembourg**, before the **Foreign Affairs Council of the European Union**, Polish Foreign Minister **Radosław Sikorski** laid an explosive dossier on the table. The **White Book on Russian Sabotage and Subversion Acts Against the Member States of the Council of the Baltic Sea States**, compiled by the **Polish Institute of International Affairs (PISM)**, catalogues with surgical precision the clandestine operations that **Moscow** has been conducting against its neighbours for years — sometimes decades.

This is not an ideological pamphlet. It is a rigorous compilation of documented incidents: **severed submarine cables**, **systematic GNSS jamming**, **targeted disinformation campaigns**, and cognitive destabilization operations. **Poland**, holding the rotating presidency of the **EU Council**, chose this precise moment to force its European partners to confront a reality that some still preferred to call "tensions" or "isolated provocations."

### Sikorski facing the hesitant: the moment of collective European clarity

**Sikorski** demanded before his counterparts an **immediate reinforcement of intelligence cooperation** between member states and the creation of a **common data-sharing system**. He insisted on the need to increase collective pressure on **Putin**. This white book did not appear out of nowhere: it crystallizes a heightened awareness that accelerated since autumn **2024**, when cables linking **Estonia** to **Finland** and **Latvia** to **Sweden** were severed under circumstances that left no doubt about their deliberate nature.

Since then, the pace of incidents has only increased. The **Russian shadow fleet**, electronic jamming operations, digital influence campaigns — all the pieces of a geopolitical puzzle that **Warsaw** had the courage to assemble publicly before the **27 European partners**.

*Things need to be named clearly: Putin's Russia has been waging total hybrid war against Europe for years. This white book is not a revelation for Western intelligence services — it is a major political act. Warsaw is forcing Europe to collectively sign an acknowledgment of aggression. Those who still resist this formulation have a problem of honesty, not of analysis.*

## The Catalogue of Hybrid Crimes: Critical Infrastructure in the Crosshairs

### The vulnerability map laid bare by PISM

The **PISM** report maps attacks against **critical infrastructure** across the Baltic region with a granularity that is dizzying. **Submarine fiber-optic and power cables** have become preferred targets — not only for their strategic value, but because their destruction is difficult to formally attribute and slow to repair. The **Russian shadow fleet** — tankers and cargo ships operating under flags of convenience — has been implicated in several incidents, with dragging anchors or loose equipment serving as improvised sabotage tools.

Operations targeting **power grids**, **pipelines**, and **communications hubs** are also documented. The objective is not necessarily to destroy — sometimes it is simply to demonstrate **vulnerability**, to create a persistent sense of insecurity, and to cost the targeted countries money and attention. It is a war of attrition that dares not speak its name, and one that democracies still struggle to officially classify.

### GNSS jamming: an invisible weapon with very real effects on civilians

The **systematic jamming of satellite navigation systems (GNSS)** across the Baltic region is one of the white book's most alarming chapters. Hundreds of commercial flights have reported navigation disruptions over the **Baltic Sea**, **Finland**, the **Baltic states**, and **Poland**. Ships have had their positioning systems jammed, dangerously complicating docking manoeuvres in ports such as **Tallinn**, **Riga**, and **Helsinki**.

This practice, which security experts describe as **low-risk electronic warfare** for the aggressor, causes real disruptions without providing formal proof of an act of war. **Moscow** can deny, dilute, and attribute events to unidentified sources. Victim governments must document, analyse, and corroborate — a slow process that benefits the aggressor and drains national response resources.

*GNSS jamming is the perfect weapon for a regime that has understood how democracies paralyse themselves when faced with attribution uncertainty. Putin is not trying to win a battle — he is trying to exhaust, discourage, and fragment. And it works, to a degree, as long as Europe fails to institutionalize a collective, binding response.*

## Cognitive Operations: The Invisible Front of Structured Disinformation

### Manufacturing doubt, fragmenting European societies from within

The third pillar of the white book concerns what **PISM** calls **aggressive cognitive operations**. These are structured disinformation campaigns targeting European public opinion with carefully constructed narratives designed to amplify existing divisions, weaken trust in democratic institutions, and sow doubt about the true nature of the Russian threat. These operations are not the work of a few isolated trolls — they are coordinated, funded, and rely on sophisticated distribution networks that use **artificial intelligence** to multiply their reach.

In **Germany**, **France**, **Italy**, and across much of **Central Europe**, campaigns have targeted elections, referenda, and debates about aid to **Ukraine**. Fake social-media accounts, front-facing news websites, algorithmic manipulation — all of this constitutes an influence arsenal whose effectiveness no serious observer can still question.

### Baltic societies on the front line of Russia's narrative war

The countries directly targeted by the white book — **Estonia**, **Latvia**, **Lithuania**, **Poland**, **Finland**, **Sweden**, **Germany**, **Denmark** — are also those with the largest **Russian-speaking communities** or the most exposed borders with **Russia** and **Belarus**. **Moscow** exploits these vectors with a precision one can only begrudgingly admire before fighting it with every necessary ounce of resolve.

**Estonia** and **Latvia**, in particular, have developed exemplary countermeasures: media literacy education, early detection of hybrid narratives, cooperation between public services and civil society. These models should be extended across the entire **European Union** — which is precisely what **Sikorski** demanded in **Luxembourg** before his counterparts.

*I am struck by the contrast between the sophistication of Russian attacks and the sluggishness of European institutional responses. Democracies operate at a structural disadvantage: they must persuade, deliberate, and vote. Autocracies decide and strike. Closing that responsiveness gap without sacrificing our values — that is the real challenge of the century for democratic Europe.*

## Sikorski's Response: Toward a Collective Architecture for Hybrid Defence

### Intelligence cooperation: the nerve centre of modern inter-state warfare

**Sikorski**'s call for a **reinforced intelligence cooperation** framework between **EU** member states addresses a well-identified structural gap: the **27 members of the Union** share too little information about Russian hybrid threats. Each country manages its own portfolio of incidents, often confidentially, without the others benefiting from this shared learning — which is nonetheless vital.

The creation of a **common data-sharing system** — whose precise contours remain to be defined in upcoming negotiations — would make it possible to detect recurring patterns, anticipate new waves of attacks, and coordinate responses. It is technically feasible. It is politically difficult, because it requires countries jealous of their intelligence sovereignty to accept a level of transparency they have never consented to in other multilateral contexts.

### The NATO Ankara summit as a major strategic amplifier

The white book's presentation comes less than three weeks before the **NATO summit scheduled in Ankara on July 7–8, 2026**. The timing is deliberate. **Warsaw** is seeking to embed the Russian hybrid threat within the collective security architecture — not just as a European issue but as an Atlantic one. Could **Article 5 of the North Atlantic Treaty** apply to a series of hybrid attacks that are sufficiently serious and documented? The question is now being raised explicitly in diplomatic circles.

The Baltic allies, **Finland**, and **Sweden** — recently integrated into **NATO** — have been pushing in this direction for several months. The Polish white book gives them the factual corpus the debate was missing. The convergence between documented proof and political will is rare in diplomacy; this time, it finally seems within reach.

*The real question at Ankara will not be how many billions for Ukraine — even if that is crucial. It will be: is NATO prepared to formally characterize Russia's hybrid campaign as an ongoing act of aggression? If yes, the legal and political consequences are considerable. If no, Putin will have won another battle without firing a single visible missile.*

## Europe Facing the Mirror: Assessment of Existing Responses and Their Gaps

### What has already been done — and what remains structurally insufficient

The **EU** has not been entirely passive in the face of the hybrid threat. The **NATO Strategic Communications Centre of Excellence** (StratCom) in **Riga**, the **Cyber Excellence Centre in Tallinn**, the **PESCO** mechanisms dedicated to resilience — all of these initiatives exist, function, and produce tangible results. But they remain fragmented, underfunded, and insufficiently integrated into a coherent doctrine at the level of the **27**.

The problem is also political: certain member states — by historical tradition, residual economic dependency, or electoral calculation — still baulk at explicitly designating **Russia** as a systemic hybrid threat. The Polish white book forces that designation. That is its primary merit, beyond the document's considerable archival value in its own right.

### Reasons for hope: a Union that learns fast when it truly decides to

Since **2022**, the **EU** has demonstrated a collective response capacity that would have seemed impossible just a few years earlier. **Economic sanctions** of unprecedented scale, **military support to Ukraine** that would have been inconceivable before **February 24, 2022**, a spectacular acceleration of defensive integration — this momentum can be applied to the hybrid threat if the political will in the capitals is genuinely there.

The **PISM** white book provides the map. **Sikorski** has pointed the direction with clarity. It now falls to the **27** to decide whether they truly want to march together — or continue managing separately a war that **Moscow** wages collectively and methodically against all of them.

*Europe has the tools. It has the evidence. It now has — finally — the document that synthesizes everything with rigour. What it still lacks is the collective conviction that this hybrid war deserves the same level of commitment as the kinetic war in Ukraine. Let us hope Luxembourg marks a turning point in that necessary awakening.*

## What the Experts Say: Hybrid War as a Durable New Security Normal

### A conflict paradigm redefined by Moscow over several decades

Security analysts who have studied Russian military doctrine for years are not surprised by the white book's contents. What surprises them is rather the delay with which Western democracies integrated these concepts into their actual strategic planning. **Moscow** practises what experts call the **"grey zone"**: below the threshold that triggers **Article 5**, but well above the level of an ordinary diplomatic incident.

This grey zone is designed precisely to paralyse democratic decision-making systems, whose requirement for consensus and irrefutable proof creates delays in action that authoritarian regimes do not face. Europe must learn to respond quickly and forcefully without waiting for absolute certainty of attribution — which, in hybrid warfare, never fully arrives and is not meant to.

### The concrete operational recommendations of the PISM white book

Beyond the diagnosis, the document presented by **Sikorski** formulates precise operational recommendations. Three main axes can be identified: first, strengthening **critical infrastructure resilience** with binding technical standards at the European level; second, creating a **permanent hybrid crisis cell** capable of coordinating responses in real time; and third, adopting a **regime of automatic sanctions** triggered as soon as an act of sabotage is attributed to a state with sufficient confidence.

These three recommendations are ambitious. They will face institutional and political resistance. But they have the merit of clarity — and in today's security environment, clarity is already a political victory in its own right against the deliberate opacity of Russian strategy.

*The debate over attribution thresholds is fundamentally a debate about our collective political courage. Acting on 80 percent certainty rather than waiting for a 100 percent that never arrives — that is what hybrid doctrine concretely demands. Europe must come to terms with this, or accept continuing to absorb blows it can never effectively return.*

## The Russian Shadow Fleet: Warsaw's Maritime Sabotage Weapon Unmasked

### Anonymous vessels as attack vectors against submarine infrastructure

One of the most striking elements of the Polish white book concerns the **Russian shadow fleet** — those hundreds of ships operating under **flags of convenience** from states such as Panama, the Marshall Islands, or Palau, whose real activity far exceeds simple sanctioned oil transport. **PISM** documents how several incidents involving damage to **critical submarine cables** in the **Baltic Sea** coincide geographically and temporally with these vessels' trajectories, creating a body of circumstantial evidence that Swedish, Finnish, and Estonian investigative authorities have progressively made public.

The technique is simple in principle: dragging anchors or poorly secured equipment serve as improvised but devastatingly effective sabotage tools against **fiber-optic cables** and **submarine electrical interconnections**. Plausible deniability is built into the operational model — it suffices to plead accident, incompetence, or difficult weather conditions. The result: months of costly repairs for victims, zero sanctions for the aggressor.

### Identifying and tracking the shadow fleet as a collective intelligence challenge

Identifying and tracking these vessels in real time is one of the most concrete operational challenges the white book poses to member states. **AIS spoofing** — the falsification of **Automatic Identification System** data that is supposed to make maritime navigation transparent — has become a documented practice of the Russian shadow fleet. Ships declare themselves at one location while physically operating elsewhere, masking their movements near sensitive infrastructure in the **Baltic Sea**.

Several Nordic countries have begun deploying complementary surveillance systems based on satellite and radar data to work around this problem. These capabilities remain national and fragmented — again, the mutual coordination that **Sikorski** recommends presents itself as an urgent operational necessity, not merely a diplomatic wish.

*The shadow fleet is the perfect embodiment of Russia's plausible-denial strategy. Faceless ships, ownerless anchors, severed cables with no official responsible party. Against this model, Europe needs integrated collective maritime surveillance — not as an option, but as a shared national security imperative.*

## The Hour of Reckoning: What Europe Has Learned and Still Must Learn from Warsaw

### Real progress, a persistent structural lag against a growing threat

Since **Ukraine**'s full-scale invasion in **2022**, **Europe** has accelerated its thinking on the hybrid threat. Joint exercises, information-sharing protocols, investments in **submarine cable resilience** — all of these are concrete, measurable advances. But the pace remains insufficient given the documented intensification of Russian operations. The Polish white book lays bare this acceleration of the threat and directly challenges the capitals that have chosen to look away.

It is significant that it is **Poland** that has assumed this leadership. **Warsaw** endured decades of Soviet domination and carries an acute awareness of the Russian danger that some Western partners have still not viscerally internalized. **Poland** devotes **4 percent of its GDP to defence** today — the highest ratio in **NATO** — and that shows in the quality of its strategic analysis.

### The Polish model: from historical victim to continental security leader

By taking this leadership in documenting and presenting the Russian hybrid threat before the entire **EU**, **Poland** is executing a remarkable geopolitical transformation. It is no longer simply a state on the eastern flank of **NATO** demanding security guarantees — it is becoming an active producer of collective security for the entire **European Union**. That is a considerable shift in posture, one that will be noted in **Moscow** and should be consistently saluted in **Brussels**.

The convergence of **analytical expertise**, **financial commitment to defence**, and **diplomatic will** is rare in international politics. **Poland** in **2026** illustrates what it truly means to take one's security seriously in a degraded geopolitical environment — and it is showing the way to those who are still lagging behind.

*There is something profoundly right about the fact that Poland — which paid so dearly for Russian expansionism in the twentieth century — is the country now carrying this dossier before all of Europe. History does not automatically teach wisdom, but when it speaks this loudly and this clearly, one would be well advised to finally listen.*

## Conclusion: Warsaw Has Done Its Part — Now Europe Must Play Its Role

### A major diplomatic act, a collective burden that is only beginning

The presentation of the Polish white book on Russian sabotage and subversion in the Baltic region is one of the most significant diplomatic gestures of Poland's presidency of the **EU Council**. **Sikorski** did not improvise — he prepared, documented, sought the right moment, and acted with determination. The result is a body of evidence that now makes it difficult for any European government to pretend ignorance of the scale and systematic nature of the Russian hybrid threat that has been documented for months.

What **Poland** accomplished in **Luxembourg** on **June 16, 2026** was to transform an intelligence dossier into a collective European political act. That documented clarity feeds into the discussions at **Ankara**. It reinforces the position of the Baltic and Scandinavian countries. It embarrasses those in **Western Europe** who preferred to maintain a comfortable ambiguity toward **Moscow**.

### The real challenge of tomorrow: structural solidarity or fatal fragmentation

The real hybrid war of tomorrow will be fought in **critical digital infrastructure**, **interconnected energy networks**, and integrated military command systems. Those who still believe that **Putin's Russia** distinguishes between peacetime and wartime are fundamentally mistaken. For **Moscow**, the war is permanent, the domains are multiple, and the rules of international conduct are merely constraints to be methodically circumvented. Against this, **Europe** has only one viable response: structural solidarity, armed with evidence, translated into concrete and lasting action.

*I have no absolute certainty about what the 27 will decide after Luxembourg. But I know one thing: the countries that share borders with Russia or Belarus no longer have the luxury of strategic doubt. For them, this white book is a matter of national survival. For the others, it is a question of basic solidarity. Both motivations combined should be enough to drive action.*

## Columnist's transparency note

### Editorial stance

I am not a journalist but a **columnist and analyst**. My expertise lies in observing and analysing the geopolitical, economic and strategic dynamics that shape our world. My work is to take political strategies apart, to understand global economic movements, to put the decisions of international actors in context and to offer analytical perspectives on the changes that are redefining our societies.

I do not claim the cold objectivity of traditional journalism, which stops at reporting facts. **I claim analytical clarity**, rigorous interpretation and a deep understanding of the complex issues that concern us all. My role is to give meaning to the facts, to place them in their historical and strategic context, and to offer a critical reading of events.

### Method and sources

This text keeps the basic distinction between **verified facts and interpretive analysis**. The rule never changes: a factual claim is published only when a verifiable source supports it, and the sources this article actually used are listed under **Sources**, never here.

**Primary source families** used by the publication, when the story has them: official statements from governments and international institutions, public statements by political leaders, reports from intergovernmental organisations, dispatches from recognised international news agencies.

**Secondary source families**: specialised publications, internationally recognised news media, analyses from established research institutions, reports from industry organisations.

When an article cites statistical, economic or geopolitical data, it comes from the institutions that produce it (intergovernmental organisations, central banks, national statistics offices), and the exact institution is named under **Sources**.

### Nature of the analysis

The analyses, interpretations and perspectives in the analytical sections of this article are a **critical, contextual synthesis** based on the information available, the trends observed and the expert comments cited in the sources consulted.

My role is to interpret these facts, to set them in the context of today's geopolitical and economic dynamics, and to give them a coherent meaning within the larger story of the changes shaping our time. These analyses reflect expertise built through continuous observation of international affairs and an understanding of the strategic mechanisms that drive global actors.

This article describes a documented state of affairs on its publication date, not a prediction: later developments may shift its outlook. No update is promised in advance; when an article is corrected or completed, the change is dated in the text.
