NATO's top Europe commander drafts "Theory of Victory" for possible Russian attack on eastern flank
Supreme Allied Commander Europe Alexus Grinkevich is preparing a strategy document called "Theory of Victory" outlining how NATO would defeat a possible Russian attack on its eastern flank, with a focus on drones, minimally-crewed systems, and AI-based targeting. The unclassified version, obtained by Bloomberg, will be presented in Poland on October 12. Grinkevich's spokesman stressed the document is "purely defensive" and aims to convince any adversary that victory is impossible.
Key points
- The document, titled "Theory of Victory," is being drafted by Supreme Allied Commander Europe Alexus Grinkevich.
- It will be presented in Poland on October 12; Bloomberg obtained the unclassified version.
- It outlines how NATO would integrate drones, minimally-crewed systems, and AI-based targeting into a defense of the eastern flank, combined with ground forces under the "NATO Eastern Flank Deterrence Initiative."
- Grinkevich's spokesman, Colonel Martin O'Donnell, said the document is "purely defensive" and aims to deter by convincing a potential adversary that victory is impossible.
- The strategy calls for increased defense investment and better training, and for collective counteraction to hybrid threats.
- NATO allies are debating how to split spending between traditional weapons such as tanks and newer technologies validated by the war in Ukraine.
- The United States sent allies a questionnaire over the summer to assess defense spending and support for Trump administration policy, and asked about additional forces that could be committed to Grinkevich's plans.
- Estonia is redeploying a key brigade from Tapa to Jõhvi, about 50 km from the Russian border, under an "active defense" concept; Lithuania and Poland are drafting a cross-border evacuation plan for the Baltic states.
Why it matters
The "Theory of Victory" is the most concrete public statement yet of how NATO would fight a Russian attack on its eastern flank. It marks a doctrinal shift toward integrating low-cost drones, minimally-crewed systems, and AI-based targeting into the Alliance's conventional defense plans — capabilities that have come to the fore during Russia's full-scale invasion of Ukraine. The document is also a signal of internal Alliance debate over how to allocate rising defense budgets between traditional heavy equipment and newer technologies, and comes against a backdrop of reported Russian nuclear threats, Baltic force redeployments, and U.S. consultations with allies about the future American military commitment to Europe.
What happened
NATO's Supreme Allied Commander Europe, Alexus Grinkevich, is preparing a strategy document titled "Theory of Victory" that lays out how the Alliance would respond to a possible Russian invasion of NATO territory. An unclassified version was obtained by Bloomberg; Grinkevich is scheduled to present the document in Poland on October 12.
The strategy focuses on integrating new defense technologies — inexpensive drones, automated systems with minimal crews, and AI-based target detection and engagement — with traditional weapons. In the event of an attack, NATO would block the invasion using a combination of ground forces and other resources under the "NATO Eastern Flank Deterrence Initiative," and after gaining freedom of maneuver would seek to destroy the adversary's command-and-control system to defeat its forces rapidly.
The document frames NATO as "purely defensive" and aims to convince a potential adversary that victory is impossible. It calls for increased defense investment, better training, and collective counteraction to hybrid threats. Grinkevich's spokesman, Colonel Martin O'Donnell, declined to discuss specifics but said the Alliance's goal is to preserve NATO's advantage and, if necessary, win in the event of an attack.
How Ukrainian sources describe it
All available sources are Ukrainian outlets, so the framing cannot be directly contrasted with international reporting. Ukrainian coverage centers Grinkevich as "Головнокомандувач Об'єднаних збройних сил НАТО в Європі" and foregrounds NATO's preparation to repel a possible Russian attack on the eastern flank, explicitly framing Russia as the aggressor. Reporting highlights Russia's nuclear threats and stresses that the strategy integrates capabilities that emerged after Russia's full-scale invasion of Ukraine in 2022.
Background
NATO allies have significantly increased defense spending but are debating how to divide it between traditional weapons and newer technologies highlighted by the war in Ukraine. The "Theory of Victory" is presented as explicitly defensive, intended to convince a potential adversary that victory is impossible while avoiding unintended provocations. Russia has warned NATO of possible nuclear use if the Alliance attempts to block Kaliningrad. Estonia is redeploying a key brigade from Tapa toward Jõhvi, about 50 km from the Russian border, under an "active defense" concept, and Lithuania together with Poland are developing a cross-border evacuation plan for the Baltic states.
