US intelligence agencies reported on August 7 that Russian President Vladimir Putin may carry out limited attacks against NATO member countries between autumn 2026 and 2029 as a means to test NATO’s resolve and attempt to break the alliance [1, 2, 3, 4, 5, 6]. The possible attacks could take various forms, including cyberattacks, the deployment of unmarked armed groups to seize territory, drone incursions, cruise missile strikes, and small-scale land incursions [1, 2, 3, 4, 5, 6].
Recent events are cited as early signs of Russia probing NATO’s defenses. These include a Russian cruise missile that landed inside Polish territory, a NATO member, in late July 2026, as well as a drone incursion into Romanian airspace in May 2026 [1, 2, 3, 4, 6]. Although a small-scale ground invasion is considered the most extreme and least likely scenario at present, intelligence assessments say its likelihood may grow over time [1, 2, 3, 4, 5, 6].
Article 5 of the NATO treaty mandates collective defense in case of an armed attack on a member state. However, it remains unclear how NATO would respond to cyber or hybrid attacks that fall below the threshold requiring Article 5 activation [1, 2, 3, 4, 6]. Colonels representing NATO confirmed they are preparing for multiple scenarios and maintaining readiness for deterrence and defense. Colonel Martin O’Donnell said, “We are always thinking through and preparing for all possible scenarios. NATO is watching the situation closely and is ready to deter and defend if necessary” [1, 6].
Putin’s motivation is believed to be driven in part by political pressure at home due to difficulties in the war in Ukraine and his desire to achieve some form of victory [1, 2, 3, 4, 5, 6]. Heather Conley of the American Enterprise Institute said, “It has always been a goal [of Russia’s] to challenge the credibility of NATO and to separate the United States from its allies” [1, 6]. She added in Mandarin that the real issue lies in how the US would react once such an event occurs [1].
Reports also indicate US munitions stocks, including long-range precision missiles and short-range Stinger missiles, are under strain due to sustained support for Ukraine and other conflicts. However, Pentagon spokesman Sean Parnell denied claims of depleted stockpiles, stating, “We have everything required to strike at the time and place of the President’s choosing... we have a deep, ready arsenal to defend our people and our interests” [1, 2, 3, 4, 5, 6].
NATO and US officials continue to monitor the situation closely as the potential window for limited Russian attacks looms. Military exercises and strategic planning are ongoing to ensure readiness against any provocations or incursions by Russia.
