NATO Commander to Warn Russia Against Attacking Alliance
NATO deterrence will take center stage on Monday as the alliance’s senior military commander prepares to address potential Russian attacks. US General Alexus Grynkewich, Supreme Allied Commander Europe, is expected to outline his approach during a security conference in Warsaw, Poland.
His remarks come amid growing concerns among NATO members about alleged Russian sabotage, interference, and other activities targeting countries supporting Ukraine. Consequently, alliance officials want to demonstrate their readiness to respond to potential aggression while reassuring members along Europe’s eastern border.
Grynkewich plans to explain what he calls his “theory of victory,” outlining how NATO could maintain its military advantage during a confrontation. According to his spokesperson, Colonel Martin O’Donnell, the approach relies on existing deterrence and defence plans. However, the commander also believes allies must prepare now for an increasingly complex international security environment.
O’Donnell said the strategy aims to discourage aggression while ensuring the alliance can respond effectively if an attack occurs. Therefore, Grynkewich’s address is expected to communicate NATO’s preparedness without revealing sensitive operational details. The alliance traditionally protects its military plans, particularly those concerning a potential confrontation with Russia.
The planned speech follows several incidents that Western officials associate with Russian hybrid operations. These activities can include sabotage, cyberattacks, interference, and other actions that fall below the threshold of conventional warfare. Moreover, officials have expressed concern that such incidents could cause serious harm if they escalate or affect civilian infrastructure.
One recent incident involved the discovery of a drone carrying explosives at a German airport, intensifying concerns about potential security vulnerabilities. Nevertheless, publicly available details do not establish responsibility for every incident attributed to suspected Russian activity. NATO members continue assessing these threats while considering appropriate ways to strengthen their defences.
The alliance faces a difficult challenge because hybrid operations often create uncertainty about how and when to respond. Unlike a conventional military assault, these activities may involve unclear responsibility and actions designed to remain below the threshold of open conflict. As a result, NATO must balance deterrence with careful assessment to avoid unnecessary escalation.
NATO civilian chief Mark Rutte has urged member states to remain calm while continuing their support for Ukraine. He has also stressed that allies should understand the risks posed by Russia without underestimating the alliance’s collective strength. Meanwhile, European governments have continued reviewing their military capabilities and security arrangements.
The debate comes as uncertainty surrounds the future scale of the US military presence in Europe. The Pentagon is reviewing American deployments across the continent, with officials expected to announce findings toward the end of 2026. Consequently, European allies are considering how to maintain defence readiness if Washington changes its force commitments.
Several European countries have already begun strengthening their armed forces amid concerns about regional security and long-term reliance on American support. Grynkewich’s speech will therefore serve both as a message to Moscow and as reassurance for NATO members. Ultimately, NATO deterrence remains a central part of the alliance’s effort to prevent conflict while preparing for potential threats.
