US General Alexus Grynkewich, NATO’s Supreme Allied Commander Europe, will outline his “theory of victory” at a Warsaw security conference on Monday — a rare public signal meant to halt what Western officials call Moscow’s increasingly reckless hybrid campaign against Ukraine’s backers.

NATO’s top military commander is expected to deliver a warning to Russia on Monday over the alliance’s ability to counter any attack, as worries grow over the threat from Moscow. NATO officials have said US General Alexus Grynkewich — the alliance’s Supreme Allied Commander Europe — will elaborate his “theory of victory” over any potential attack at a security conference in Warsaw.
The move comes as NATO seeks to send a message to Moscow to halt what Western officials describe as a “hybrid” campaign of sabotage and interference against Ukraine’s backers in the war against Russia. Fears have grown in recent months that the Kremlin is stepping up its actions after high-profile incidents, including the discovery of an explosive-laden drone at a German airport.
The choice of venue is deliberate. Warsaw sits on the alliance’s eastern edge, within sight — strategically speaking — of the borders the warning is about. The audience will include the governments most exposed to any Russian escalation, and the message is addressed as much to them as to Moscow: the alliance’s plans exist, they are current, and they would work.
The phrase comes from Grynkewich’s own staff. “The Supreme Allied Commander Europe’s theory of victory is simple: maintain NATO’s advantage, which is consistent with and grounded upon the alliance’s deterrence and defence plans,” Colonel Martin O’Donnell, the general’s spokesman, said last week. “But given the unsettled and complex global security environment, we need to set conditions now to deter aggression and, if necessary, win if attacked.”
In substance, the theory appears less a new war plan than a public articulation of the existing one. NATO traditionally guards its defence plans against any Russian attack in near-total secrecy. A “theory of victory” presented in unclassified form is therefore a communications instrument first: it tells Moscow a plan exists without saying what it is.
Reporting suggests the document is meant to clarify how the alliance would handle a possible incursion into NATO territory, to show the public what sits behind the surge in defence spending, and to press allies for more investment — integrating traditional weapons with the new capabilities that have emerged since Russia’s full-scale invasion of Ukraine in 2022.
What the Warsaw speech will not do, by all indications, is disclose. NATO officials are managing expectations: the intervention looks unlikely to divulge many new details of the alliance’s strategy. The actual plans — force dispositions, timelines, the integration of new capabilities — will stay classified, which means the public will hear the doctrine but not the machinery.
We also do not know how Moscow reads any of this. The Kremlin has not publicly responded to the announcement of the speech, and its standard reply to Western sabotage allegations is denial coupled with counter-accusation. Whether the warning lands as deterrence or as provocation — whether it cools the hybrid campaign or becomes the pretext for its next phase — is the unanswerable question at the centre of the week.
Because the threat picture has changed shape. Western officials now describe Moscow’s “hybrid attacks” as more reckless than at any point in the war — sabotage, interference, and intimidation aimed not at Ukraine directly but at the countries arming it. The explosive-laden drone found at a German airport is the incident officials keep returning to: an attack on a civilian target inside a NATO state, attributed — without public evidence — to Russian direction.
The timing also tracks the battlefield. Western officials assess that the Kremlin’s forces are stalled in Ukraine, and that the hybrid campaign is intensifying precisely because the conventional one is not delivering. A stalled army with an active sabotage arm has motive to escalate sideways, into the Poland–Baltic corridor, where attribution is murky and response thresholds untested.
And there is the money. Allied defence budgets have surged since 2022, and publics ask what the spending buys. A “theory of victory” connecting budgets to a credible plan — as Germany’s latest commitments to Kyiv illustrate — is also domestic politics: reassurance for voters as much as warning for Moscow.
The most interesting thing about the “theory of victory” is that it exists in public at all. NATO’s institutional instinct, honed over seventy-five years, is silence: plans are classified, capabilities are implied, adversaries are left to guess. Breaking that silence suggests the alliance’s leadership has concluded that ambiguity is now the greater risk — that Moscow is misreading NATO’s restraint as unreadiness, and the hybrid campaign’s growing recklessness is the evidence.
That judgment may be right, but the instrument is blunt. A public theory of victory cannot calibrate: it reassures Warsaw and alarms Moscow in the same sentence, and the Kremlin’s incentive is to test the gap between the two. Deterrence works when the threatened response is credible and bounded; “win if attacked” is credible, but its bounds are deliberately hidden — which is exactly what makes miscalculation possible.
The deeper question is whether the speech addresses the actual campaign. Hybrid warfare operates below the level where a “theory of victory” applies: no invasion, no Article 5. Warning Moscow that NATO would win a war it is not fighting does not obviously deter the sabotage it is allegedly conducting. The speech may be aimed less at the Kremlin’s covert operators than at its General Staff — a reminder that the grey zone has a ceiling.
The second-order effects will be felt first in allied capitals’ budget debates. A Supreme Allied Commander publicly linking victory to “conditions set now” is a spending argument wearing a uniform: expect the speech to be quoted in every European parliament where defence appropriations are contested this autumn. The arms industry — already running at wartime tempo — gets another demand signal, and the integration of new capabilities since 2022 (drones, long-range fires, air defence depth) becomes the procurement story of the year.
Beyond budgets, the speech resets the diplomatic weather. Russia’s continuing strikes on Ukraine’s energy grid will now be read against an explicit NATO counter-threat, which hardens both sides’ positions ahead of any winter diplomacy. And for the Global South, the week’s lesson is about attention: a single general’s speech in Warsaw will dominate the security conversation while the wars without a “theory of victory” — the ones with no alliance behind them — fight on in the dark.
Watch three things. First, the text: whether Grynkewich names the hybrid campaign and attributes it to Moscow, or keeps the warning general. Second, Moscow’s reply: dismissal is certain, but its register matters — a snap exercise near the Baltic would signal the warning was received as a threat. Third, the next incident: the hybrid campaign’s tempo after Warsaw will be read as the Kremlin’s answer.
In the best case, the speech does what deterrence statements should: nothing happens, and the nothing is the proof. In the middle case, the hybrid campaign continues — deterred from escalation, undeterred from harassment. In the worst case, a misjudged probe meets a misread warning, and the “theory of victory” gets its first field test. NATO’s bet is that saying the words makes the third case less likely.
Through the Western lens, the Warsaw speech is overdue clarity. The hybrid campaign — drones at airports, sabotage of infrastructure, interference operations across Europe — is read as a coherent Kremlin strategy to punish Ukraine’s backers without triggering Article 5, and the only answer to grey-zone pressure is to make the conventional threat unmistakable. Grynkewich’s “theory of victory” is, in this frame, the military counterpart to the political message: attack us and you lose; harass us and the same machinery answers.
This lens also treats the public nature of the speech as the point. NATO’s plans have always existed; what was missing was Moscow’s certainty that they would work. Deterrence is a psychological transaction, and a Supreme Allied Commander describing — even in outline — how the alliance wins is meant to close the gap between NATO’s real capability and the Kremlin’s perception of it. The eastern flank’s reassurance is the dividend: after months of anxious diplomacy over Ukraine’s future, Warsaw, the Balts, and Bucharest hear that the guarantee is not rhetorical.
Through the Eastern lens, the speech is theatre with a budget line. Moscow’s standing position — voiced most recently by Foreign Minister Sergey Lavrov in answer to NATO’s “defensive alliance” claims — is that the alliance’s eastward posture is the aggression, and that talk of “victory” over Russia is the confession of an offensive doctrine wearing defensive clothes. In this reading, Grynkewich is not warning against an attack; he is normalising the idea of a NATO–Russia war to publics being asked to fund it.
This lens also disputes the premise of the hybrid campaign narrative. Russia denies directing sabotage inside NATO states, and treats Western attribution — the German airport drone prominent among the cited incidents — as assertion without evidence, useful for justifying the defence-spending surge. From Moscow’s vantage point, the “theory of victory” changes nothing in practice: Russia’s planning already assumes NATO’s full conventional weight, and a speech does not move a single battalion.
Through the Global South lens, the Warsaw speech is a reminder that Europe’s security conversation is still conducted as if the rest of the world were the audience rather than a stakeholder. The “theory of victory” is framed entirely around a NATO–Russia contingency; the wars actually killing people this week — in Sudan, in Gaza, in the Sahel — do not appear in it. For capitals that have spent two years being lectured about a rules-based order, the spectacle of the alliance publicly gaming out victory over a nuclear power reads as the order’s authors reserving the right to escalation they condemn elsewhere.
There is also a material reading. Every euro spent on the eastern flank’s reassurance is a euro not spent on the development finance and debt relief the South was promised. The speech will be heard in Jakarta, Nairobi, and Brasília as confirmation of a hierarchy: European security is existential and funded without debate; everyone else’s is a line item.
US General Alexus Grynkewich is NATO’s Supreme Allied Commander Europe — the alliance’s top military commander, responsible for all NATO operations. He is expected to use a Warsaw security conference on Monday to outline his “theory of victory,” warning Russia that the alliance can counter any attack. His spokesman, Colonel Martin O’Donnell, describes the theory as maintaining NATO’s advantage within existing deterrence plans.
It is the framework, articulated by General Grynkewich’s staff, for how NATO would defeat a Russian attack on allied territory: maintain the alliance’s advantage, grounded in existing deterrence and defence plans, and “set conditions now to deter aggression and, if necessary, win if attacked.” Presented in unclassified form, it is meant to signal capability without revealing operational detail.
Western officials describe a Russian campaign of sabotage and interference targeting Ukraine’s backers — arson, cyber intrusions, intimidation operations, and incidents such as an explosive-laden drone found at a German airport. They say the attacks have grown more reckless as Russian forces stall in Ukraine and risk significant loss of life. Moscow denies directing such operations.
NATO insists it remains a defensive alliance with no intention of attacking Russia, and officials say the Warsaw speech will reveal no new offensive detail. The “theory of victory” is framed as a counter-attack doctrine — what the alliance would do if attacked — not a first-strike plan. Moscow rejects the defensive framing as a fiction.
