Russia’s NATO Drone Incursions have emerged as a serious test of the alliance’s resolve. In recent days, Moscow has sent drones into the airspaces of Poland and Romania, raising alarms across Europe and forcing NATO to confront the delicate balance between deterrence and escalation. These repeated violations appear to be deliberate moves by the Kremlin to test NATO’s resolve, credibility, and unity at a time when the alliance faces mounting pressure over the war in Ukraine.
Russia has upped its covert war against NATO in recent days by sending drones into the airspaces of allied members Poland and Romania. The incursions, which have come in rapid succession, have shaken European capitals and left policymakers scrambling to wonder if Moscow is systematically probing NATO’s commitment and credibility.
The Incidents: Drones Crossing NATO Lines
Russian-made Geran drones crossed NATO airspace at least twice this week, according to defense authorities. Romanian fighter aircraft pursued one for nearly 50 minutes before it turned back into Ukraine. Poland also reported incursions, leading Warsaw to scramble air defenses and issue a harsh warning to Moscow.
These are not random technical malfunctions. Experts maintain that the trend indicates deliberate intrusions intended to test NATO’s air defenses, challenge response times, and — most significantly — gauge political will.
NATO’s Initial Response: Operation Eastern Sentry
As a countermeasure, NATO has initiated “Eastern Sentry,” a combined military exercise to strengthen its eastern front. It joins resources from Denmark, France, the UK, Germany, and other members. Notably, it is designed for the drone threat: combining early warning systems, electronic warfare resources, and enhanced coordination between ground-based air defense and fighter jets.
The warning is unequivocal — NATO would like to be able to demonstrate watchfulness without moving into actual fighting. But as previous clashes have demonstrated, credibility cannot be established by exercises.
Why Drones, Why Now?
Unlike traditional aircraft or missiles, drones provide Moscow with an inexpensive, low-risk weapon of provocation. They are compact, difficult to intercept, and frequently deniable. Through drones, Moscow treads the thin line between harassment and aggression — pressuring NATO without invoking Article 5, the collective defense provision of the alliance.
These incursions must also be seen in the broader context of the war in Ukraine. Russia, bogged down in a grinding conflict, is seeking to divert NATO’s focus, sow doubt among allies, and test how far it can stretch the alliance’s patience.

The Dilemma for NATO
NATO now faces a classic strategic trap:
If it underreacts, Russia may conclude the alliance is unwilling to defend its members in practice, weakening deterrence.
If it overcompensates, NATO is at risk of escalating to direct Russia–NATO conflict — something the alliance has gone out of its way to prevent since February 2022.
This balancing act has characterized NATO’s stance since the Ukraine war began. The alliance has supplied arms to Kyiv, beefed up its eastern flank, and imposed sanctions on Russia — but always held back from measures that would be interpretable as direct military intervention. Drones in NATO airspace threaten to obfuscate the line uncomfortably.
Probing the Alliance’s Cohesion
These events also challenge NATO from within. Various members hold diverse threat perceptions: Poland and the Baltic states interpret Russia as an existential threat, whereas nations like Hungary or even Germany might be inclined towards restraint. Moscow is aware of these differences and attempts to play them off against each other.
By launching drones into the skies over NATO, Putin is essentially asking: Will the alliance really be one, or will indecision break its backbone?
Historical Echoes
This is not the first instance of Russia testing NATO’s limits. Throughout the Cold War, Soviet planes regularly probed NATO’s airspace, and Russian fighters have recently buzzed allied and U.S. vessels in the Black and Baltic Seas. What elevates the current situation to a riskier threat is the context of an existing hot war in Ukraine and the risk-taking Kremlin leadership.

Strategic Implications
Deterrence at Stake
NATO’s legitimacy rests on the presumption that aggression will be confronted by a combined, crushing response. Continuing UAV incursions undermines that perception if ignored.
The Role of Technology
The gray areas of modern warfare — drones, cyber war, hybrid warfare — pose problems for NATO’s old playbook. Article 5 was drafted for tanks and missiles, not cheap UAVs to be brushed off as “accidents.”

The Road Ahead
NATO will need to determine how to establish red lines. Possibilities include:
Publicly threatening Moscow with retaliation for repeated incursions.
Enlarging air defense coordination throughout Eastern Europe.
Examining proportionate countermeasures (e.g., shooting down Russian drones over Ukraine) to increase the costs.
Credibility on the Line
The drone incursions into Romania and Poland are not spontaneous provocations. They are deliberate actions by Moscow to test NATO’s mettle, reveal cracks in cohesion, and normalize low-level sovereignty violations.
For NATO, the test is existential: an alliance that cannot defend its own skies risks losing the credibility upon which its very existence rests. Through deterrence, through diplomacy, or through decisive signaling, NATO needs to mark a line — or face losing to Putin to continue to press and press until a much more perilous escalation takes place.
The next few weeks will tell if NATO can reconcile prudence with strength, or if Moscow has discovered yet another method of eroding the world’s greatest military alliance.
