A limited Russian operation in Narva could test NATO without beginning with a full-scale invasion. The Institute for the Study of War (ISW) scenario places Estonia's border city at the center of a campaign using tactical drones to exploit local unrest and propaganda. Its political as well as military goal would be to force the alliance to decide how far its collective defense commitment extends.
ISW does not describe an invasion as an established plan. It says a large-scale Russian attack on a NATO state is extremely unlikely, while warning that Vladimir Putin has other conventional options for escalation. The institute also said it saw no signs of Russian force buildup near the Baltic states. It described the Narva scenario as a hypothetical test of NATO's response, not a forecast of an inevitable attack.
Narva is presented as the most vulnerable setting in this hypothetical case. The city has a largely Russian-speaking population and has faced an intense propaganda campaign on Russian social media channels. Propastop previously reported messages with separatist maps and symbols that also called for sabotage and protests.
The imagined operation would begin inside the city, not with a broad armored advance. Information from the ISW analysis, Russian agents already operating in Narva could seize public buildings and areas near the border bridge and riverside promenade. The study names the Narva Museum and the City Government building as possible targets. The group would then proclaim a so-called People's Republic of Narva and ask Moscow for protection, claiming that Estonia's Russian population was being persecuted.
Against the backdrop of the scenario's publication, the Russian side temporarily restricted access to the border area opposite Narva. ISW said the restrictions were in effect from September 16 to 26 and limited movement in the area, including access to the Narva River. They also barred the carrying of weapons in certain areas.
That narrative would let the Kremlin deny launching a direct invasion. Moscow could present the crisis as an internal Estonian matter and say its role was limited to protecting Russian citizens. The political language would matter: the operation would aim to create uncertainty before NATO agreed on a military response.
The proposed support would involve unmanned systems, including FPV drones and loitering munitions, alongside longer-range aircraft launched from Russian territory. They could target routes used by Estonian forces. The systems described in the study could reach up to 60 kilometres and might also be supported by relay stations in the Baltic Sea. ERR, citing the scenario, pointed to possible electronic warfare as well as fibre-optic FPV drones that could make it harder for Estonian and allied forces to move near the border.
That range would matter because Narva lies about 40 kilometres from the Jõhvi military base. The ISW scenario suggests Moscow would use drones to slow or block an Estonian move towards the city while avoiding a large ground deployment. A wider operation could consume resources committed to the war in Ukraine and trigger a stronger NATO response.
Wider pressure around the Baltic region provides the immediate context. Sweden and Germany have held exercises there, while Spanish fighter aircraft have monitored Russian planes over the sea. A Kremlin missile struck two kilometres from Poland's border; Poland has responded by strengthening its military posture. Prime Minister Donald Tusk told Parliament that intelligence assessments pointed to a Russian plan involving hybrid attacks with drones and missiles against countries supporting Ukraine. Emmanuel Macron has issued a similar warning in recent days.
ISW identifies several possible aims behind a limited strike. Moscow could try to force a dispute over the application of Article 5 and split cooperation linking the United States with Europe and the Baltic states, while diverting resources from Ukraine. The crisis could also deepen political disagreements over the scale and form of any response to Russia, giving more room to Eurosceptic and anti-NATO parties.
Estonian authorities have sought to distinguish the hypothetical exercise from an immediate security warning. The Estonian Ministry of the Interior said the situation on the eastern border remained calm on September 20. Foreign Minister Margus Tsahkna also said he did not consider Narva to be "next." The government's position is that the ISW scenario should not be read as a forecast of an imminent attack.
The line between a local operation and an attack requiring an alliance-wide decision is narrow. A Russian move in Narva would not need to seek territorial conquest to create a strategic crisis. Propaganda and local proxies could use drones to make hesitation part of the operation. ISW presents the basic danger as a calculated attempt to turn a limited incident into a test of NATO's cohesion, rather than an inevitable invasion.
