FACT-CHECK: Russian Disinformation About Poland and Ukraine — The Matryoshka Network Debunked

The EEAS-Ukrainian Center Against Disinformation Report

A joint report by the European External Action Service (EEAS) and the Ukrainian Center Against Disinformation documented 80 Russian information interference operations specifically targeting Ukraine’s EU accession process between January 2025 and May 2026. These operations employ recurring narratives: Ukraine is not ready for the EU; Ukraine’s integration will cost European taxpayers too much; Ukraine is a corrupt and unstable state; and—the most common narrative—Ukraine is ruled by extremist nationalists.

VERDICT: TRUE AND WELL-DOCUMENTED. The figure of 80 operations is taken from an official joint report by two recognized institutions. It is consistent with analyses by other disinformation monitoring organizations, notably EUvsDisinfo, the EEAS’s monitoring platform. The existence of a systematic and organized campaign targeting Ukraine’s EU accession is documented beyond a reasonable doubt.

Target Narratives — Why EU Membership Is Being Targeted

Why is Russia specifically targeting Ukraine’s EU accession process? Because this accession represents Ukraine’s definitive integration into the West—its transformation into a permanent member of a system of values and institutions that is fundamentally opposed to the Russian authoritarian model. A Ukraine within the EU is living proof that liberal democracy can function in the post-Soviet space. For Putin, this is an existential threat to the legitimacy of his own regime.

Disinformation narratives targeting Ukraine’s accession therefore aim at several audiences simultaneously: European citizens who might oppose enlargement, Euroskeptic politicians in member states, and Ukrainian public opinion itself—to sow doubt about the value of this accession. It is a campaign that is both external and internal.

80 interference operations to block Ukraine’s accession to the EU. Putin is so terrified by the idea of a democratic Ukraine in the EU that he is devoting massive resources to preventing this accession. This fear speaks volumes about the threat that a functioning democracy on his doorstep poses to him.

The Reality of Polish-Ukrainian Relations in June 2026

The Russian disinformation narrative seeks to convince Polish and Ukrainian audiences that tensions between the two countries are insurmountable, that reconciliation is impossible due to history, and that Ukraine is not truly a reliable partner for Poland. This narrative draws on real historical grievances—notably the Volhynia issue and periodic tensions surrounding historical memory—but exaggerates them to the point of distortion.

VERDICT: FALSE AND PROVABLE. Poland is de facto the main transit country for Western military and humanitarian aid to Ukraine. It hosts the largest number of Ukrainian refugees in Europe. It has delivered significant military equipment. Regular diplomatic meetings at the highest levels maintain the dialogue. Periodic tensions over historical issues are real—but they do not undermine the fundamental strategic cooperation between the two countries.

Polish-Ukrainian Reconciliation as a Russian Strategic Target

Polish-Ukrainian relations are a priority target of Russian disinformation because they represent the most visible example of reconciliation between two nations with a painful history. Poland and Ukraine have genuine historical grievances—Volhynia in 1943, tensions during the interwar period, and differing interpretations of complex historical figures. If Russia can exploit these grievances to break or weaken the Polish-Ukrainian alliance, it isolates Ukraine from its closest regional ally and weakens NATO’s entire eastern flank.

This is why every diplomatic incident between Warsaw and Kyiv—no matter how minor—is immediately seized upon and amplified by Russian disinformation networks. The Matryoshka network did not create the controversy over the honorary military title—it exploited and amplified it beyond all reasonable proportion.

Russia wants Poland and Ukraine to hate each other. Because if they hate each other, aid stops flowing, refugees have nowhere to turn, and NATO’s eastern flank becomes vulnerable. It is a geopolitical strategy disguised as an information operation. Naming it doesn’t make it any less dangerous—but it at least helps to counter it.

Identifying Fabricated Quotes

Among the Matryoshka network’s most effective tactics in this campaign was attributing fabricated quotes to respected Polish figures—politicians, journalists, and historians—asserting positions on Ukraine that these individuals never expressed. These fake quotes are designed to appear credible because they are based on real people, and to go viral because they contain shocking or provocative statements.

VERDICT: FALSE AND DOCUMENTED. The Kyiv Independent contacted several of the figures whose names were used—all denied having made these statements. Checks of the dates and formats of the cited publications confirm that they are fabrications. The fake media logos used contain typographical and layout errors that can be detected by comparing them to the originals. These fakes are sophisticated—but not perfect.

How to Spot These Disinformation Campaigns

There are several indicators that can help identify content from the Matryoshka network and similar operations. First, check the exact URL of the articles—domains such as “tvp-info-news.pl” or “reuters-europe.info” are not the official domains of these organizations. Second, search for the quotes on the official websites of the people quoted—if the quote isn’t there, it’s likely fabricated. Third, check the creation date of the account spreading the information—recently created accounts with high activity levels are often bots.

These checks take less than five minutes. They are within the reach of any internet user. And they are the best individual defense against disinformation—long before platforms or governments have had time to react. Media literacy is the most effective and least costly countermeasure against disinformation campaigns.

Five minutes of fact-checking can undo a week’s worth of work by the Matryoshka network. That is the promise of fact-checking—not the elimination of disinformation (which is impossible), but its slowing down. Every reader who checks before sharing is a cell of informational resistance. I repeat this at every opportunity.

The EEAS Report: 80 Operations, a Coherent Strategy

The joint EEAS–Ukrainian Center Against Disinformation report, documenting 80 interference operations from January 2025 to May 2026, reveals a coherent strategy targeting every stage of Ukraine’s EU accession process. These operations intensify around major political milestones: the opening of accession negotiations, European Commission progress reports, discussions on financial aid, and any diplomatic incident between Kyiv and an EU member state.

VERDICT: TRUE AND DOCUMENTED BY OFFICIAL SOURCES. This report is a high-value primary source—it originates from an official European institution and a recognized Ukrainian government organization. Its figure of 80 operations is not an estimate—it is a documented tally of identified and analyzed operations. The consistency of the Russian strategy that emerges is striking: targeting EU accession is a priority for Russian intelligence, not a marginal activity.

EUvsDisinfo — the European monitoring platform

EUvsDisinfo, the EEAS’s disinformation monitoring platform, has documented thousands of cases of pro-Kremlin disinformation since its creation in 2015. In its recent analyses from 2026, it confirms that disinformation targeting Ukraine’s relations with its neighbors—notably Poland, Hungary, Romania, and Slovakia—increased sharply in 2025–2026, in parallel with the progress of Ukraine’s EU accession process.

This correlation—the further accession progresses, the more disinformation intensifies—is in itself indicative of the Kremlin’s fear of this accession. If Ukraine’s membership in the EU were not a threat to the Russian regime, Russia would not be investing so heavily in operations to prevent it.

Eighty operations in 17 months—that’s about one per week. And these are only the ones that have been documented. The actual campaign is certainly broader. This intensity speaks to something fundamental: Putin is convinced that a Ukraine in the EU is a threat to his political survival. And on this specific point, he is probably right.

The Ukrainian Center Against Disinformation — A Growing Institution

The Ukrainian Center Against Disinformation (CCD) is a Ukrainian government agency established in 2021 to monitor, analyze, and respond to disinformation campaigns. Since 2022, its budget and staff have been significantly increased. Its cooperation with the European EEAS represents the development of a transatlantic information partnership—complementary to the military and economic partnership.

This joint EEAS–CCD report is a product of that cooperation: two institutions sharing information, coordinating their analyses, and publishing joint findings. This transparency—publishing the results of analyses rather than keeping them confidential—is itself a countermeasure: it helps the media, fact-checkers, and the public identify ongoing campaigns.

Social Media Platforms—Unwitting Accomplices

One aspect that is rarely criticized enough is the role of social media platforms in the spread of Russian disinformation. The algorithms of Twitter/X, Facebook, TikTok, and Telegram favor emotionally charged and polarizing content—exactly what the Matryoshka network produces. These platforms are not neutral actors in the information war: their engagement-based business models mechanically amplify the most viral disinformation content.

The European response—notably the Digital Services Act (DSA), which imposes transparency and anti-disinformation obligations on major platforms—is a step in the right direction. But its enforcement remains insufficient to counter the speed at which the Matryoshka network operates. Regulating these platforms remains one of the most urgent challenges in the information war.

Facebook’s algorithms amplify Russian disinformation. Not out of malice—but by design. An algorithm that maximizes engagement favors outrage, fear, and shock. That is exactly what Matryoshka produces. We have built machines that work for Putin. This is a reality that should keep us awake at night.

Debunking Matryoshka — A Collective Responsibility

This article fact-checked five claims circulating in the Matryoshka network’s disinformation campaign targeting Polish-Ukrainian relations. The findings: CLAIM 1 (Ukrainian Nazi elites): MANIPULATION THROUGH DECONTEXTUALIZATION. CLAIM 2 (80 interference operations): TRUE AND DOCUMENTED. CLAIM 3 (insurmountable Polish-Ukrainian tensions): FALSE AND PROVABLE. CLAIM 4 (false Polish quotes): FALSE AND DOCUMENTED. CLAIM 5 (targeting the EU accession process): TRUE AND DOCUMENTED.

Two out of five claims are true—the two that document Russian disinformation activities themselves. The three disinformation claims are all false or manipulated. That is the factual verdict. It should leave no doubt about the reality and scope of Operation Matryoshka.

What Russian Disinformation Reveals About Its Own Fears

The fact that Russia is devoting significant resources to weakening Polish-Ukrainian relations and blocking Ukraine’s accession to the EU reveals, by implication, what it fears most. A Ukraine firmly anchored to the West, a member of the EU and potentially of NATO, sovereign and prosperous—that is the Kremlin’s nightmare. Because such a Ukraine demonstrates that the authoritarian post-Soviet model is not inevitable. That democracy can function within the region that Putin considers his sphere of influence.

Every Russian disinformation campaign is therefore also an expression of fear. And in that fear, paradoxically, lies a reason for hope.

Disinformation reveals the fears of those who produce it. Matryoshka fears the Polish-Ukrainian alliance. It fears Ukraine’s accession to the EU. These fears are Ukraine’s strongest cards. By naming them, we help Ukraine play them.

Polish-Ukrainian Relations Will Outlast Matryoshka

Polish-Ukrainian relations have weathered challenges far greater than the operations of the Matryoshka network. They have weathered centuries of painful history, wars, foreign occupations, and the traumas of Volhynia. Since 2022, it has withstood the strain of hosting millions of refugees and the intense military cooperation that this war demands. It will survive a disinformation campaign—no matter how sophisticated—because the two countries’ shared strategic interests are stronger than any fabricated narrative.

But this survival must not be taken for granted. It requires constant vigilance—from journalists who fact-check, platforms that moderate, governments that coordinate, and citizens who verify before sharing. It is a collective responsibility. This fact-check is a modest contribution to that collective effort.

A Final Word—For Skeptical Readers

If you’ve seen content circulating claiming that the Zelenskyy government is “Nazi,” that Poland is withdrawing its support for Ukraine, or that Ukrainian EU membership is rejected by Poles—check it out. These narratives originate from well-documented Russian disinformation networks. They have been debunked by reputable organizations. They do not deserve your trust without verification. And once verified, they deserve to be called what they are: propaganda serving a regime that fights with lies what it cannot defeat with weapons.

Ukraine is on the right side of history. So is the truth.

Fact-check complete. Conclusion: Russian disinformation about Poland and Ukraine is well-documented, systematic, and debunkable. Matryoshka is real. Its operations are identifiable. And they can be countered through fact-checking, transparency, and information sharing. That is the work I am doing here. And I will continue.
