The assessments outline scenarios ranging from cyberattacks to a small-scale incursion, while officials weigh how firmly the alliance would respond.

Recent U.S. intelligence assessments indicate that Russian President Vladimir Putin may try to test NATO’s resolve by launching a limited attack against one of the alliance’s member states in the coming years, according to three sources familiar with the material.

The intelligence documents consider various escalation scenarios, ranging from a cyberattack to a small-scale invasion aimed at testing NATO’s unity and commitment to Article 5, which declares that an attack against one member is an attack against all, but does not necessarily trigger a response from the entire alliance.

According to the sources, he may choose the Baltics or Poland as the most likely direction for escalation. These assessments remain the subject of discussion in analytical reviews.

Context and Possible Scenarios

According to U.S. and NATO officials, Putin could choose to escalate against NATO if he fails to find a “way around” ending the war in Ukraine; the window for such action extends from now into the coming years.

cyberattacks or other cyber operations;
small-scale ground or air operations aimed at testing the alliance’s unity and adherence to Article 5;
likely targets – the Baltic states or Poland.

“NATO is monitoring developments, and we are prepared to deter and defend as needed, which we continue to demonstrate.”

The reports also mention incidents involving violations of NATO airspace: in May, a drone carrying explosives struck a high-rise building in Romania, while Russian forces attacked a nearby Ukrainian port, injuring several people; last year, during an attack on Ukraine, NATO aircraft shot down several Russian drones that had violated the alliance’s airspace.

“Monitoring drones and the threats associated with them, including in a hybrid context, is something we know from the past.”

– Alexander Dobrindt

In this context, Germany recently examined an incident at an airport; on Friday, the National Security Council, chaired by Chancellor Friedrich Merz, met to discuss the situation.

“The presence of a drone carrying explosives at an airport is a new threat scenario.”

According to the sources, the United States continues to assess dwindling weapons and ammunition stocks; some air defense systems and munitions have been used in operations, and supplies are declining. Organizations also point to an increase in civilian casualties caused by Russian long-range weapons from January through June compared with the previous year.

One night this week, Russian ballistic and anti-ship missiles killed at least 17 people and wounded dozens more; Ukrainian forces were unable to intercept all of them.

This context is also influencing senior commanders’ plans for future conflicts – including a potential escalation against NATO or a possible confrontation with China in the Pacific.

“The U.S. has massive amounts of ‘munitions,’ especially of certain types,” Trump said on Truth Social late Thursday night. “Additionally, large amounts are being manufactured and shipped to the U.S. as needed. Defense companies are building the largest number of plants and factories in our country’s history.”

U.S. and European diplomatic efforts to end the war between Russia and Ukraine continue. Sanctions against Moscow continue to pressure the country’s economy, but they have not stopped its aggression against Ukraine.

Ultimately, these assessments underscore the readiness of the United States and its allies to respond to various scenarios – both in Europe and beyond – and not leave decisions for later.
