US intelligence agencies reportedly believe that Russian President Vladimir Putin could launch an attack against a NATO member in the coming years, potentially before the end of the decade. The assessments, described in new intelligence reports, suggest that Moscow could seek to test the alliance’s political and military resolve through actions ranging from cyberattacks to a limited physical incursion into NATO territory.
According to the reported assessments, the purpose of such an operation could be as much political as military. A carefully limited attack could test whether NATO members would respond together, while an attack conducted during the continuing war in Ukraine could also be intended to deepen divisions within the alliance.
The reported shift in the US assessment is significant. Previously, American intelligence agencies had believed that Putin would avoid provoking a NATO country while Russia remained engaged in its war against Ukraine. That judgement has reportedly changed this year. US officials cited in the reports said a possible Russian attack on NATO territory while the Ukraine war continues could be aimed at splitting the alliance.
The scenarios under consideration vary considerably in scale. They include cyberattacks, the use of soldiers wearing unmarked uniforms to seize territory and a small-scale incursion into a NATO country. The most extreme scenario, involving an incursion into NATO’s eastern flank, is reportedly considered unlikely. Its probability, however, is assessed as increasing over time.
The estimated window for any potential attack reportedly stretches from this autumn to 2029. The assessment therefore does not describe an imminent invasion as inevitable, but rather identifies a period in which the possibility of Russian action against NATO could increase.
The Baltic states and Poland are considered the most likely potential targets in the event of an attack, according to the reported intelligence assessments. Their position on NATO’s eastern flank places them at the centre of concerns about possible Russian military or hybrid operations.
Lithuania’s government has recently said that its military intelligence possesses information indicating that Russia could be considering attacks against critical infrastructure in the Baltic states using Ukrainian drones. Such an operation would represent another possible form of confrontation, in which the origins and responsibility for an attack could be obscured while its consequences were felt within NATO territory.
The possibility of Russia testing NATO through limited or ambiguous actions is particularly significant because the alliance’s response would be as important as the initial attack itself. A large-scale military assault would present a clear challenge, but cyberattacks, covert operations or small incursions could create greater uncertainty over how and when NATO should respond.
The reported intelligence assessments also carry significance because US intelligence agencies successfully predicted Russia’s 2022 invasion of Ukraine. European allies, however, did not take those warnings sufficiently seriously before the war began. The experience has since become an important reference point when assessing new intelligence concerning Russia’s intentions.
The current assessments also coincide with a separate incident involving a drone found carrying explosives at Halle/Leipzig airport during the night of Wednesday. US intelligence assessments reportedly point towards a Russian connection. The reported findings go further, suggesting that the drone probably belonged to the Russian government, while a US defence official in Europe was quoted as saying that the United States had concluded that the drone came from a Russian intelligence service.
The incident adds another dimension to the concerns surrounding possible Russian activity in Europe. Unlike a conventional military assault, the use of a drone linked to a foreign intelligence service could blur the distinction between military operations, sabotage and other forms of pressure. Such actions can create uncertainty about attribution while potentially targeting infrastructure far from any conventional battlefield.
German authorities have adopted a more cautious public position. Federal Interior Minister Alexander Dobrindt described the incident as a possible “hybrid” attack by “foreign powers”, rather than directly attributing responsibility to Russia.
That distinction reflects the difficulty of dealing with actions that fall below the threshold of conventional warfare. A cyberattack, covert operation or suspected act of sabotage can have serious consequences without necessarily producing the unmistakable circumstances of an armed invasion. For NATO, the challenge would be to determine not only who was responsible, but also whether the action constituted an attack requiring a collective response.
The intelligence assessments reportedly indicate that the most extreme scenario remains unlikely. Yet the possibility is considered more significant as time progresses, particularly if Russia concludes that NATO’s political cohesion can be challenged without provoking a unified response.
The prospect of an attack before 2029 therefore rests not on a prediction that war between Russia and NATO is inevitable, but on an assessment of possible future behaviour. The scenarios range from digital disruption to limited territorial incursions, with the potential objective of testing the alliance at a moment when uncertainty, political division or competing national interests could affect its response.
For NATO’s eastern members, particularly the Baltic states and Poland, the reports reinforce concerns about the vulnerability of critical infrastructure and territory close to Russia. For the alliance as a whole, they raise a broader question about deterrence: whether the perception of unity is strong enough to prevent a limited challenge from becoming a larger confrontation.
The reported change in US intelligence assessments also highlights how quickly judgements about Russian intentions can evolve. Washington had previously assessed that Putin would avoid provoking NATO while fighting in Ukraine. That assumption has now reportedly been revised.
With the potential timeframe extending from this autumn to 2029, the central issue is no longer simply whether Russia could launch a conventional attack. It is whether Moscow might attempt to exploit the uncertain boundary between war, cyber conflict, covert operations and limited military action to test the willingness of NATO members to act together.
The experience of the Ukraine war has already demonstrated the consequences of intelligence warnings being underestimated. The latest assessments place renewed emphasis on the alliance’s ability to interpret ambiguous threats, maintain unity and decide how to respond before a limited confrontation develops into something much larger.
