Russia cannot fight NATO, no matter the threats

The numbers tell their own story. In June 2026, Vladimir Putin told a Kremlin event that 700,000 Russian soldiers were fighting in Ukraine. The authorised strength of the Russian army, by his own decree, exceeds 1.5 million, with a further 800,000 civilian positions within the military establishment. By the president's own account, the force actually engaged in combat amounts to less than half the army's paper strength. Those figures alone make the idea of a Russian attack on NATO barely credible.

The material gap Putin cannot close

Western fears of a Russian strike on NATO allies have circulated since before the invasion of Ukraine in 2022. They have persisted even as Russia's military became demonstrably overstretched. The logic from Moscow's perspective has a certain internal coherence: Western involvement in Ukraine has deepened steadily, from limited arms deliveries and intelligence sharing to what Russia regards as direct participation in attacks on its cities. Dmitriy Peskov, the Kremlin press secretary, recently described European nations as "directly participating" in those attacks. The Russian leadership sees a pattern of escalation that, in its view, demands a more forceful response to restore deterrence.

Intent and capacity are not the same thing. Russia may harbour genuine grievances and a desire for retaliation against what it perceives as a quasi-belligerent alliance. Its ability to act on those beliefs is constrained by a military that cannot achieve its minimum objectives in Ukraine, let alone open a second front against an alliance with overwhelming conventional superiority. The gap between what Russian leaders might want and what they can actually do is where the real analysis begins.

Finland redraws the strategic map

Finland's accession to NATO has altered the strategic calculus in ways that receive less attention than they deserve. Before Finland joined the alliance, Russia's north-western border with a NATO member ran roughly 200km, between Norway and the Murmansk region. Finland's membership added more than 1,300km of border. Finnish officials estimate that Russia has built infrastructure to deploy about 80,000 troops along that border. That is a meaningful force, but it is also a force whose preparations would be visible. Commercial satellite imagery and open-source monitoring have made large-scale military buildups far harder to conceal than they were before 2022, when the visible Russian concentration ahead of the Ukraine invasion was widely reported in advance.

More importantly, Finland's membership means that key Russian military infrastructure, the logistics nodes around Murmansk, Leningrad Oblast and the Baltic approaches, is now within reach of NATO air power and long-range strike systems. Finland fields more than 800,000 trained reservists on paper, a figure that requires some scepticism given the country's population of 5.5 million, but one that still translates into hundreds of thousands of mobilised soldiers if required. Since joining NATO, Finland has moved quickly to integrate into alliance command structures and planning. Together with Sweden, it is already developing counter-drone measures modelled on Ukrainian experience.

In a NATO-Russia conflict, Finland would function as a well-defended staging ground for strikes deep into Russian territory. One-way attack drones, combined with Finnish access to advanced stealth aircraft, would put much of Russia's north-western military infrastructure at risk in ways that Ukraine, operating alone, simply cannot replicate. Russia would face attacks not on warehouses or logistics depots but on missile assembly plants and the residences of senior government figures. The damage NATO could inflict on Russian war-making capacity bears no comparison to what Ukraine has managed with far fewer resources.

Why even a limited war fails Moscow

Russia has battle-hardened troops after four and a half years of war, and it has developed a greater capacity for complex missile and drone strikes against rear areas. In theory, a limited Russian attack using its most experienced forces, combined with deep strikes on NATO territory, could produce initial gains. The theory collapses quickly under examination.

Even a brief, localised conflict confined to the Baltic states would not resolve Russia's underlying security problems. It would deepen them. The arrival of reinforcements and materiel from the rest of NATO would, over the medium term, make a Russian defeat in a conventional war all but certain. That calculation does not even account for what Ukraine would do with Russia's western borders stripped of defenders. A NATO-Russia war would present Kyiv with some of its best opportunities to retake lost territory.

Poland's army, to take the largest force on NATO's eastern flank, lists about 220,000 soldiers on paper. Polish sources put the actual peacetime front-line contingent at 65,000 to 70,000. In a full mobilisation, a country of more than 37 million people could field far more, as Ukraine has demonstrated with a smaller population base. The disparity in available manpower between Russia, already heavily committed in Ukraine, and the combined forces of NATO's eastern members alone, is stark.

Sabotage as substitute for war

If direct military confrontation is beyond Russia's capacity, Moscow still has options for pressuring European states. The most likely path is an expansion of the sabotage and covert operations that have already surfaced across the continent. Russia has recruited individuals through social media to carry out arson, reconnaissance and similar tasks. These recruits are less skilled than the professionals behind operations such as the Skripal poisonings in 2018, but they are cheaper and harder to trace back to Moscow. They are also, by their nature, strategically indecisive. Burning a warehouse or vandalising a pipeline does not stop weapons reaching Ukraine.

Alleged plots to assassinate European defence officials involved in supporting Ukraine represent a more aggressive version of the same approach. In theory, targeting officials could make their colleagues more reluctant to back Ukraine. In practice, as the past decade of Russian covert operations has demonstrated, these actions are rarely interpreted as Moscow intends. They tend to produce blowback, hardening European resolve rather than softening it. The strategy persists because Russian leaders continue to believe it will eventually work, not because the evidence supports them.

The maritime dimension

Russia has so far not responded to Western seizures of vessels from its so-called shadow fleet, nor to the unexplained sinkings of ships linked to Russia's arms trade off European coasts. Under international law, Moscow has some basis for calling these acts illegal: the vessels are subject to national sanctions rather than United Nations sanctions, a distinction that matters in legal terms even if it makes little practical difference to ship owners. Putin has threatened to respond in kind, and that threat is one of the more immediate steps Russia could take to re-establish what it regards as deterrence.

Seizing or sabotaging European shipping would be a calibrated step, visible enough to register as a response but stoppable before it escalates into a wider confrontation. It carries its own risks. Any attack on shipping in European waters would invite a NATO response under the alliance's maritime security framework, and the same material constraints that make a land war impractical apply at sea. Russia's surface fleet has not grown stronger during the Ukraine war.

The calculation that keeps the peace

Russian leaders have shown themselves capable of overconfidence and misperception, as the invasion of Ukraine demonstrated. The material situation, however, still precludes carrying a war into Europe while Ukraine remains unconquered. A direct attack on NATO, even a limited one, would give the alliance a rationale for far more open involvement in Ukraine than it has so far adopted. Striking a drone factory in Poland might satisfy a short-term desire for retaliation; it would also trigger the very escalation spiral that Moscow claims it wants to prevent.

None of this means Europe can relax. Russia will continue to probe, sabotage and threaten. The hybrid campaign against European infrastructure and officials is likely to intensify as Moscow searches for leverage it cannot gain through conventional force. What the material balance does mean is that the most feared scenario, a Russian military push into NATO territory, remains the least likely. The constraints are not political or diplomatic. They are arithmetic.
