US intelligence warns Putin could test NATO with limited attack amid munitions shortages
New US intelligence reports warn that Vladimir Putin could test NATO's resolve with a limited attack on a member country within the next few years, as American munitions stocks dwindle from transfers to Ukraine and the conflict with Iran.
US intelligence shifts assessment
New US intelligence reports, first reported by the Wall Street Journal on 7 August 2026, warn that Vladimir Putin could test NATO's resolve with a limited attack on a member country within the next few years. US analysts previously considered it "improbable" that Putin would provoke a NATO country while Russia remained engaged in the war in Ukraine. That assessment changed at the beginning of 2026, as Putin came under increasing pressure from setbacks in Ukraine and domestic pressure to secure a victory. Ukrainian drones are inflicting growing damage on both Russian military forces and the oil industry, while Russian troops advance slowly along the front, suffering heavy losses. The concern among intelligence officials is that Putin could become more dangerous if cornered, and they are assessing whether Moscow intends to intensify aggressive actions toward European allies in the near future.
Scenarios and timeframe
The intelligence reports envision a range of scenarios, from cyberattacks to a small-scale ground incursion on the alliance's eastern flank. In the latter case, this could involve sending armed groups without identifying insignia to seize territory. According to the reports cited by Deutsche Welle, Russia could take such steps in the period from autumn 2026 to 2029. The probability of the most extreme scenario, a limited ground invasion, remains low but is gradually increasing. Such a step was previously considered extremely unlikely because it would trigger NATO's Article 5 on collective defense. However, that article does not clearly define a response to cyber or hybrid threats. The Telegraph's headline characterized the potential timeline as "within weeks," while other sources describe a window of years.

Munitions shortages
The new assessment compounds existing concerns about US munitions shortages. Stocks of several key weapons systems have diminished due to transfers to Ukraine and the conflict with Iran. Among the reserves considered at risk are the long-range Precision Strike Missile and Army Tactical Missile System (ATACMS), as well as short-range Stinger surface-to-air missiles, according to US officials. These are munitions the US military would need in a future conflict with Russia or China. The shortages come as the United States faces simultaneous military commitments, including arms deliveries to Ukraine since the Russian invasion and requirements tied to the conflict with Iran.
Probing actions and alliance concerns
US and European leaders say they are seeing increasing signs of Russian actions designed to test NATO's response capacity. These include Russian cruise missiles landing in Polish territory and drones entering Romanian airspace. US officials stated that Putin's objective in any attack on a NATO country while the war in Ukraine continues would be to divide the alliance and create splits among member states. Heather Conley, a senior fellow at the American Enterprise Institute, addressed the possibility of a Russian incursion and the uncertainty it would create.

Calling NATO's credibility into question and separating the United States from their allies has always been a goal of Russia.
