Radosław Sikorski says recent Kremlin threats could be constructing the justification for a manufactured attack and wider military retaliation.
Warsaw, June 2026
Polish Foreign Minister Radosław Sikorski has warned that Russia may be preparing a false-flag operation designed to create a pretext for military escalation against European countries supporting Ukraine. His assessment followed statements by Russian President Vladimir Putin suggesting that Moscow could retaliate if drone attacks against Russian territory were found to have originated from European states.
Sikorski described the Kremlin’s language as potentially more than a warning. He argued that it could represent the preliminary construction of a narrative in which an attack on Russian territory is blamed on a NATO or European country, allowing Moscow to present a subsequent response as defensive rather than aggressive.
The Polish official used the Russian term maskirovka, traditionally associated with military deception, concealment and strategic misdirection. The concept can include camouflage, disinformation, fabricated movements, misleading signals and operations intended to make an adversary misunderstand the true origin or purpose of an action.
In a false-flag scenario, an attack is conducted or manipulated so that responsibility appears to belong to another actor. The operation may be used to influence public opinion, justify retaliation or create uncertainty among governments attempting to determine what actually happened.
Sikorski emphasized that he was issuing a warning rather than presenting proof that a specific attack had already been organized. No publicly available evidence has confirmed the existence of an imminent Russian false-flag operation. His concern is based primarily on the evolution of Kremlin rhetoric, historical precedent and the broader pattern of hybrid activity attributed to Moscow.
Putin recently warned that Russia would respond if drones striking Moscow or other Russian targets were launched from European territory. He accused Western governments of helping Ukraine attack Russia while attempting to distance themselves from direct responsibility.
Sikorski interpreted those remarks as potentially preparing Russian audiences for a future claim that a European country had crossed a military threshold. If an incident were then presented as an attack launched from NATO territory, the Kremlin could argue that retaliation was necessary and proportionate.
The Polish minister compared the possible scenario with the Gleiwitz incident of August 1939. Nazi German operatives staged an attack on a German radio station near the Polish border and portrayed it as an act of Polish aggression. The fabricated incident became part of the propaganda used to justify Germany’s invasion of Poland.
The historical comparison carries particular weight in Warsaw because Poland has repeatedly warned that manipulated incidents can become instruments of strategic escalation. Polish officials argue that modern technology allows fabricated evidence, edited videos, manipulated communications and coordinated disinformation to spread more rapidly than twentieth-century propaganda.
A contemporary false-flag operation could take several forms. It might involve a drone strike, an explosion near military infrastructure, an attack on civilians or damage to a strategically important facility. Russian authorities could then attribute the incident to Ukraine, Poland or another European supporter of Kyiv before independent investigators obtained access to the site.
The ambiguity created during the first hours after an attack would be strategically valuable. Governments, journalists and intelligence services would need time to verify the origin of weapons, flight routes and operational responsibility, while Russian state media could immediately circulate a unified account.
Such uncertainty could divide NATO members over how to respond. Some governments might demand rapid deterrent measures, while others could hesitate until stronger evidence became available. The resulting political disagreement could be as useful to Moscow as the physical consequences of the alleged attack.
Poland has become one of Ukraine’s principal military and logistical supporters since Russia launched its full-scale invasion in 2022. Weapons, humanitarian assistance and other supplies have moved through Polish territory, making the country an important part of the Western support network.
Warsaw has also experienced suspected sabotage, espionage, cyberattacks and arson plots that Polish authorities have linked to Russian intelligence services. Moscow has rejected those accusations and regularly describes Polish claims as politically motivated hostility.
The security environment became more tense after Russian-made drones entered Polish airspace in 2025, forcing military aircraft to respond and leading NATO to reinforce surveillance along its eastern flank. Polish officials viewed the incursion as a deliberate test of allied defenses rather than an accidental deviation from attacks against Ukraine.
Russia has also been accused of using intermediaries to conduct operations while preserving plausible deniability. Recruiting individuals from third countries or criminal environments can make it more difficult to establish a direct institutional connection with Moscow.
This form of hybrid warfare operates below the level of a conventional invasion. It combines cyber operations, sabotage, disinformation, political influence and carefully calibrated military pressure. The objective may be to weaken an adversary without triggering the unified response that an openly declared attack could produce.
Sikorski’s warning therefore reflects concern not only about a possible single incident but about the political conditions surrounding it. A manufactured attack could become more dangerous if it coincided with aggressive rhetoric, nuclear threats or claims that NATO was already conducting a war against Russia.
Russian officials and state media figures have repeatedly raised the possibility of using nuclear weapons in response to perceived threats. Although such statements do not establish operational intent, they increase the consequences of miscalculation and make every unexplained incident more difficult to manage.
European governments face the challenge of warning their populations without presenting speculation as established fact. Excessive alarm could amplify Russian psychological operations, while insufficient preparation could leave institutions vulnerable to manipulation.
The most effective defense against a false-flag operation would include rapid intelligence sharing, independent technical investigation and coordinated public communication. Governments would need to preserve evidence, verify weapon trajectories and avoid assigning responsibility before reliable conclusions are available.
Media organizations would also face pressure to distinguish verified facts from claims released by the parties involved. Images from an attack can be authentic while explanations of who caused it remain false or incomplete.
NATO has consistently maintained that it seeks to deter Russian aggression without entering a direct war. A manufactured incident could be intended to test that balance by forcing the alliance to react under conditions of uncertainty.
Sikorski’s intervention signals that Poland wants allies to recognize the possibility before an incident occurs. Advance awareness could reduce the effectiveness of a fabricated narrative by making governments more cautious about accepting immediate accusations.
The warning does not mean that escalation is inevitable. It does, however, demonstrate how deeply distrust now shapes relations between Russia and Europe. Statements, drone movements and unexplained explosions are interpreted not as isolated events but as possible elements within a broader strategy.
In that environment, the truth becomes part of the battlefield. A false-flag operation succeeds not only when it causes damage, but when it persuades enough people that the victim was the aggressor.
