Russia’s cat-and-mouse game: Testing NATO’s skies

A wave of Russian airspace violations from the Baltics to Poland and Germany has triggered NATO consultations and revived questions over alliance unity, as Moscow appears to probe how far it can go without provoking a larger confrontation.

Tensions spiked over the Baltic Sea on Sunday when NATO scrambled German Eurofighters and Swedish Gripens to intercept a Russian Il-20M electronic surveillance aircraft.flying without a flight plan or radio contact.

German pilots shadowed the plane before handing it over to Swedish jets, a routine interception but one that underscored the strain of near-constant encounters on NATO’s eastern flank.

Estonian airspace breach triggers Article 4
Only days earlier, three Russian MiG-31 fighter jets crossed nearly nine kilometres into Estonian airspace, staying for 12 minutes before being forced out by Italian F-35s stationed in the region. Tallinn described the violation as “unprecedentedly brazen” and immediately requested NATO consultations under Article 4 of the Washington Treaty. NATO condemned the incursion as “reckless,” and European leaders warned it was no accident. On Tuesday, the alliance’s North Atlantic Council is expected to meet to address the incident.

Polish skies swarmed by drones
The Estonian case followed an episode on the night of 9th September, where more than 20 Russian drones entered Polish airspace during attacks on Ukraine. NATO aircraft and air defence systems shot many of them down. Western officials termed it the most serious spillover of the Ukraine conflict into NATO territory so far. The incident sparked sharp questions over whether NATO is fully prepared for the scale of drone warfare, with analysts warning that inexpensive unmanned systems could overwhelm the alliance’s costly Cold War-era defences.

NATO Secretary General Mark Rutte praised the rapid reaction, declaring that “our air defences were activated and successfully ensured the defence of NATO territory.” But critics pointed out that the drones should never have been able to cross into alliance airspace in the first place. A Slovakian former ambassador to NATO said the incident proved the alliance was “reacting to threats rather than deterring them,” and called for more decisive action.
 

Espionage and sabotage
Beyond the airspace confrontations, intelligence agencies warn of a broader campaign. In August, U.S. and German officials confirmed drone flights over supply routes in eastern Germany used to move weapons into Ukraine. Concentrated in Thuringia, the flights were believed to be gathering intelligence for sabotage or battlefield planning.

Earlier this year, three Ukrainian nationals were arrested in Germany and Switzerland after U.S. intelligence tipped off authorities about a Russia-linked plot involving cargo planes transiting Germany. Investigators said the aim may have been to disrupt supply chains or damage infrastructure.

Western intelligence services have also tied Moscow to other suspected operations, including fires at warehouses in Britain, an attack on a Norwegian dam, and attempts to cut undersea cables in the Baltic Sea — actions officials say were intended to bring the war closer to Europe and weaken public support for Kyiv.

German Defence Minister Boris Pistorius described the situation as a “constant cat-and-mouse game,” noting that some drones may have been launched from ships in the Baltic Sea. U.S. analysts have called the surveillance “straight-up espionage,” arguing that Moscow is trying to map which firms are producing weapons for Ukraine, how the shipments move through Germany into Poland, and when Ukrainian forces will receive them. While overt incursions like the MiG-31 flight over Estonia draw headlines, Western officials say the quieter intelligence operations may be just as dangerous, targeting the logistical backbone of NATO’s support for Ukraine.

A reminder from 2015
Looking back, in 2015, Türkiye shot down a Russian Su-24 after it briefly crossed its airspace from Syria. The pilot was killed, Russia retaliated with new missile deployments, and instead of uniting, NATO exposed its divisions.

U.S. officials privately blamed Türkiye for overreacting to what they considered a minor violation of its airspace. NATO diplomats worried Ankara was too aggressive, warning that further incidents risked escalation after Russia deployed its S-400 air defence system in Syria.

To avoid being dragged into confrontation, NATO made it clear to Ankara it could not count on alliance backing if tensions with Russia escalated because of Turkish actions. European officials stressed that if Türkiye was responsible for the escalation, it would not be able to invoke the NATO treaty.

Ankara was left largely isolated in its standoff with Moscow — a stark reminder of how fragile NATO unity can be when tested by Russian pressure.

Testing NATO’s limits
From Baltic interceptions to drones over Poland and espionage in Germany, Russia is steadily pushing at NATO’s edges. Each move stops short of open conflict but forces the alliance to respond. The challenge for NATO is no longer spotting the provocations, but deciding how far it is willing to be pushed — and whether it can hold together when tested.
