Danish intelligence warns Russia could attack NATO within months

On Thursday morning, Danish defence intelligence released a report that landed like a stone in still water: Russia might launch a limited military attack against a NATO country within months. The assessment, among the bluntest warnings yet from Western security services, described a "low but growing risk" of long-range Russian strikes on NATO infrastructure supporting Ukraine, or small-scale incursions by troops operating without insignia across a NATO border. The timing was sharp. Hours earlier, a fire had torn through a Starlink satellite station in central Poland's Masovian region overnight. Polish authorities called it sabotage.

Krzysztof Gawkowski, Poland's deputy prime minister, said the blaze had been "deliberately designed to disable the station." The facility provided internet access to Ukrainian military operations among other institutions. Gawkowski stopped short of naming Russia but said the evidence pointed that way. "Many signs suggest this aligns with Russia's new doctrine of attack," he told reporters. Prime Minister Donald Tusk had already framed such incidents as hybrid warfare—the kind of pressure that sits below the threshold of conventional war but carries real cost. Starlink has become woven into Ukraine's military communications. The fire was one incident in a widening pattern. Germany had publicly blamed Russia for an attempted drone strike on Leipzig/Halle airport earlier in September. Fires at drone factories, sabotage of rail lines—European intelligence services were investigating whether Moscow had a hand in each one. Russia denied everything.

The Danish report laid out Moscow's likely calculus. Russian military leadership, according to a source with knowledge of their thinking, believed NATO countries were already at war with Russia—not just supplying weapons and intelligence to Ukraine, but actively guiding missiles and drones. From that view, Russia had the right to respond in kind. The goal was clear: drain European resources away from Ukraine and fracture NATO unity if the alliance could not mount a collective response. The Danes warned that Russia would likely escalate its hybrid attacks in coming months, moving toward operations with "greater consequences"—destructive cyber-attacks that could cripple essential services, sabotage that risked mass casualties.

Yet the report also contained a notable hedge. An outright Russian invasion of NATO territory remained "highly unlikely," the Danish service said. But then came the qualifier: it "cannot be ruled out." The concern centered on Article 5, NATO's collective defence clause. Russian planners might calculate that NATO countries would not respond together, especially if Moscow believed the United States under Donald Trump would hesitate to defend Europe. That anxiety had weight. Slovakia's prime minister, Robert Fico, who maintains close ties to the Kremlin, had recently cast doubt on his own country's commitment to collective defence, saying he did not want Slovakia drawn into conflict "because of some article 5." Questions about American resolve had circulated through European capitals for months.

Ukrainian President Volodymyr Zelenskyy, speaking at the UN General Assembly on Wednesday, had named the stakes plainly. Russia threatened not just Ukraine but Moldova, Poland, and the Baltic states. It showed "no respect" for sovereignty across the south Caucasus and central Asia. "The more freedom Putin has to act, the more dangerous the world becomes for everyone else," he said. The Danish warning was not a prediction of imminent invasion. It was something more precise and more unsettling: a measured assessment that the risk, while still low, was rising—and that Russia was testing whether the West would hold together when tested.
