U.S. Intelligence Assesses Putin Could Test NATO Resolve with Limited Attack, According to Wall Street Journal

U.S. intelligence assessments indicate that Russian President Vladimir Putin could attempt to test NATO’s collective defense commitments with a limited assault on an alliance member in the coming years, according to a report published by The Wall Street Journal.

Citing new U.S. intelligence reports, the Journal reported that possible scenarios range from cyberattacks on a NATO country or the deployment of unmarked armed groups to occupy territory, to a small-scale land incursion along the alliance’s eastern flank. The assessments estimate that any such action could occur between this fall and 2029.

The Journal stated that Putin’s primary objective in any attack on a NATO country while the war in Ukraine continues would be to fracture the alliance rather than to seize significant territory. U.S. officials cited in the report previously believed Russia would avoid directly provoking NATO members during the ongoing conflict with Ukraine. The updated assessments revise that view amid concerns that Putin may grow more dangerous if he feels increasingly cornered.

According to the Wall Street Journal’s account of the intelligence findings, the likelihood of the most extreme scenario—a limited ground incursion—remains low, though the risk is expected to rise over time. Hybrid or gray-zone actions, such as cyber operations or operations by unidentified forces, are viewed as more plausible because NATO’s response thresholds for those activities are less clearly defined than for conventional military attacks that could trigger Article 5.

The report noted that U.S. and European leaders have already observed what they interpret as probing actions by Russia, including cruise missiles that have landed in Poland and drones that have entered Romanian airspace. These incidents have heightened concerns about Moscow’s willingness to test alliance responses.

The intelligence assessments arrive against a backdrop of strain on certain U.S. munitions stockpiles, including long-range guided missiles and air-defense interceptors, following sustained support for Ukraine and other military operations. Officials have pointed to shortages in systems such as Patriot, SM-3, and THAAD-related capabilities as a complicating factor in broader deterrence calculations.

NATO has maintained that the alliance remains prepared to deter and defend against a range of threats. A NATO spokesperson told reporters the organization continuously evaluates potential scenarios and is ready to respond as necessary.

The Wall Street Journal’s reporting, based on U.S. intelligence assessments and officials familiar with the findings, has been widely cited by other news outlets. The assessments do not indicate an imminent full-scale attack on the alliance but highlight a shift in how U.S. analysts evaluate the risk of limited Russian provocations aimed at testing NATO unity while the war in Ukraine continues.
