Western attention is shifting toward the Middle East and uncertainty is still clouding the trajectory of the war in Ukraine. In this context, the Kremlin may see a limited but meaningful opportunity to press for political advantage through a more aggressive hybrid pressure campaign. Rather than risk direct war with NATO, the campaign will be designed to probe allied thresholds, destabilize European governments, undermine transatlantic unity, and weaken Western support for Kyiv.

The pattern is already visible. Western intelligence reports confirm a fourfold increase in Russian sabotage operations across Europe from 2024 compared to previous years, with the surge continuing through 2025 and into 2026.

After absorbing steep military and economic costs, Russia entered the fourth year of the war under mounting budgetary strain and battlefield losses. Despite temporary revenue gains from higher energy prices, Ukrainian long-range strikes on oil infrastructure and a sharp depreciation of the Russian Ruble continue to weigh heavily on the Kremlin. These pressures are likely to deepen Moscow’s reliance on low-cost hybrid warfare, particularly along NATO’s Eastern flank.

Russian President Vladimir Putin needs the war to ensure the survival of his regime: A permanent war footing gives the Kremlin a way to justify sacrifices while postponing accountability for domestic decline. The war is no longer merely a foreign policy instrument but a governing mechanism that justifies censorship, internet restrictions, and broader repression.

Europe and NATO cannot spend the remainder of 2026 discussing red lines without clearly defining or enforcing them. The Kremlin appears determined to step up its hybrid pressure to fracture European resolve. To properly counter it, allied leaders should set up a hybrid response cell for the Eastern flank, the EU and NATO should carry forward an already-agreed graduated menu of automatic consequences, and Brussels should establish a Baltic resilience initiative. Failure to respond coherently and through a whole-of-society approach will pave the way for further hybrid incidents targeting European supply chains, undermining social resilience, and eroding democratic processes.

The Baltic states have emerged as a frontline of Russian gray-zone tactics, including regular aerial probing, airspace incursions, and GPS interference. In recent weeks, that pressure has taken a more politically dangerous turn. Russian-language social media channels and anonymous Telegram accounts have begun promoting a so-called Narva people’s republic in Estonia’s northeastern border region, circulating separatist imagery, mock state symbols, and claims that Russian speakers in Narva require protection from Tallinn. Estonian authorities have treated the campaign as an information operation rather than a genuine grassroots movement, but that is precisely what makes it strategically significant. The aim is not necessarily to manufacture an immediate military incident, it is to normalize the narrative architecture of one.

By reintroducing the false language of compatriot protection, staged local grievance, and pseudo-separatist symbolism, Kremlin-aligned actors can test whether a fringe online provocation can mature into a political dilemma for NATO. Recent legislative proposals by Moscow to expand the legal basis for deploying Russian forces abroad to protect persecuted populations further institutionalize this logic. If adopted, such measures would pave the way for more direct, kinetic intervention in the Baltics.

This could take the form of a deliberately ambiguous scenario in which deniable operatives, local proxies, or “little green men” seize or destabilize a small piece of territory and dare the alliance to decide whether Article 5 applies in full. This is, according to senior NATO officials, the nightmare scenario—not because it would begin a major military offensive, but because it would force a political decision under conditions of uncertainty and contested attribution.

Estonia is not the only frontline state in the crosshairs of Russian hybrid warfare. As Swedish Civil Defense Minister Carl-Oskar Bohlin recently warned, Moscow’s methods have shifted over the past year, with pro-Russian groups linked to security and intelligence services moving beyond denial-of-service attacks toward more destructive cyber operations against critical facilities across Europe. Recent attacks, including a December attack on a power plant serving half a million people in Poland and another facility in western Sweden, demonstrate how Russia and its aligned actors can disrupt critical infrastructure.

Europe and NATO should hence treat Moscow’s attacks as part of a standing campaign that requires standing instruments. First, the alliance should establish a hybrid response cell for the Eastern flank: a permanent joint mechanism that fuses intelligence, rapid attribution, and pre-agreed response options for sabotage, cyber incidents, GPS interference, and deniable incursions. This requires operational mechanisms that can move fast with the necessary political approval already built in.

Second, allies should agree on a graduated menu of automatic consequences for major hybrid incidents. Not every act of sabotage should trigger the same response, but Moscow should know in advance that attacks on critical infrastructure, repeated aviation disruption, or coordinated interference in border regions will produce predictable costs—whether in the form of sanctions, expulsions, maritime interdictions, cyber countermeasures, or accelerated military deployments on the Eastern flank. The point is to deny the Kremlin the benefit of strategic ambiguity.

Third, Europe should create a Baltic resilience initiative focused on the states most exposed to sustained pressure. That should include hardened backup systems for airports and ports, joint civil defense planning for border municipalities, and rapid support mechanisms for local governments facing disinformation-fueled unrest or service disruptions. In places like Narva, resilience is not only military. It is administrative, civic, and political.

Finally, Europe should prepare now for the most dangerous scenario: not a Russian tank thrust, but a deniable political-military provocation designed to force hesitation inside the alliance. NATO should run and publicly signal tabletop exercises for “little green men” contingencies, localized seizures, and contested-attribution incidents in border regions.

The core task for the remainder of 2026 is simple: Close the gap between hybrid warfare and organize against it. Europe and NATO must treat Russian attacks as a sustained campaign and build the faster attribution, pre-agreed consequences, and stronger resilience needed to deny Moscow the advantages of ambiguity and allied hesitation.
