New U.S. intelligence assessments indicate that Russian President Vladimir Putin may launch a limited attack on a NATO member country within the next few years, with the aim of fragmenting the alliance and testing its collective defense commitment under Article 5. These potential attacks, which could occur anytime between this fall and 2029, are likely to target countries in the Baltics or Poland.

Recent incidents, such as a drone striking an apartment building in Romania in May and cruise missiles landing in Poland late last month, are seen as signs that Russia is probing NATO's readiness. While a full-scale land incursion is considered less likely due to the automatic trigger of Article 5, concerns remain about responses to other forms of aggression, including cyberattacks.

Heather Conley, a senior fellow at the American Enterprise Institute, stated that challenging NATO's credibility and driving a wedge between the United States and its allies has long been a goal for Russia. The intelligence suggests that Putin may be seeking a victory as Ukraine makes gains, increasing the perceived need to demonstrate Russian strength.

Despite concerns about depleted munitions stockpiles due to aid for Ukraine and the conflict in Iran, Pentagon spokesman Sean Parnell asserted that the U.S. possesses the necessary resources to respond to threats. "Any adversary who confuses media noise with American weakness will discover the truth the hard way," Parnell said, according to The Wall Street Journal.

NATO has acknowledged that it is constantly preparing for various scenarios. A NATO spokesman, Col. Martin O’Donnell, stated that the alliance is vigilant and prepared to deter and defend as necessary. The challenge for NATO has historically been responding to attacks that fall below the threshold of Article 5, with allies generally preferring to avoid escalation.
