Russia's Five NATO Attack Scenarios
- Security experts warn Russia is more likely to test NATO through covert operations, undersea infrastructure sabotage, or limited territorial incursions than through an overt
- The Suwalki Gap — a narrow corridor between Belarus and the Russian exclave of Kaliningrad — is identified as one of the most critical flashpoints, where a rapid Russian advance
- Svalbard, where Russia maintains a settlement at Barentsburg under a unique international legal regime, is flagged as a potential site for a manufactured crisis that could be used
Security experts are warning that any Russian move against NATO is unlikely to begin with massed tanks and open bombardment. Instead, analysts point to a range of covert, hybrid, and limited military scenarios that could force the alliance into agonising decisions — each designed to blur the line between war and peace, and to exploit the gaps between NATO's political cohesion and its ability to respond rapidly on the ground.
Sabotage beneath the waves
The first and perhaps most insidious threat identified by analysts lies on the ocean floor. Russia is said to possess specialised units and deep-sea submarines capable of operating against critical undersea infrastructure — data and power cables, pipelines, and offshore installations. The strategic appeal of such an operation is stark: a co-ordinated attack could simultaneously disrupt communications, energy supplies, and trade, while the question of attribution might remain unresolved for days or weeks, denying NATO a clear legal or political basis for retaliation.
Little green men in Narva
The Estonian border city of Narva has for years featured in discussions of a covert Russian intervention modelled on the seizure of Crimea. The scenario envisages armed men without insignia — so-called little green men — appearing in the city, accompanied by manufactured civil unrest, local separatist movements, and categorical denials from Moscow. The absence of overt Russian markings would complicate NATO's collective-defence trigger under Article 5, creating precisely the legal and political ambiguity Moscow would seek. Tensions on NATO's eastern flank have already produced a series of military alerts in 2026.
A grab for the Baltic Sea
Analysts also flag the Swedish island of Gotland and the Finnish Åland Islands as potential targets in a Baltic scenario. Whoever controls Gotland commands one of the most strategically important chokepoints in the Baltic Sea. A Russian surprise move to install air-defence and anti-ship systems there could severely hamper NATO's ability to reinforce the Baltic states, potentially arriving before a coherent alliance response could be mounted.
An Arctic provocation at Svalbard
Far to the north, the Norwegian archipelago of Svalbard presents a different kind of vulnerability. The islands belong to Norway and are therefore covered by the NATO treaty, yet they carry a unique status under international law, and Russia maintains an active settlement at Barentsburg. Experts warn that Moscow could manufacture a crisis — invoking alleged treaty violations or the need to protect Russian nationals — as a pretext to apply pressure on Oslo or to occupy strategically significant positions. The importance of the region to Russia is not merely diplomatic: only a few hundred kilometres away lies the Kola Peninsula, home to key facilities of Russia's Northern Fleet and its sea-based nuclear deterrent. Russian military assertiveness has already drawn NATO into difficult decisions over sovereign airspace elsewhere in Europe.
The Suwalki Gap: NATO's most exposed corridor
Of all the scenarios discussed, the Suwalki Gap is regarded by analysts as among the most dangerous. This narrow strip of territory between Belarus and the Russian exclave of Kaliningrad represents the sole land connection between Poland and the Baltic states. A rapid Russian advance from Belarus toward Kaliningrad could sever that corridor before substantial NATO reinforcements arrived, effectively encircling Estonia, Latvia, and Lithuania and confronting the alliance with a fait accompli. The gap has been a fixture of NATO contingency planning for years, and its vulnerability underscores the fundamental tension at the heart of the alliance's eastern posture: the distance between political commitment and the speed of military response. Recent incidents over Latvian airspace illustrate how quickly events on NATO's north-eastern flank can escalate.
Taken together, the scenarios outlined by security experts share a common logic: they are designed not necessarily to win a conventional war, but to test the cohesion of an alliance whose strength depends as much on political unity as on military capability.
