NATO commander outlines 'block, blunt and break' strategy for responding to attack on alliance

NATO's Supreme Allied Commander Europe, U.S. Air Force Gen. Alexus Grynkewich, publicly outlined a strategy for responding to a potential attack on the alliance. He spoke in Warsaw, Poland. The Wall Street Journal, Fox News and Le Monde reported on the remarks.

Grynkewich described the approach as "block, blunt and break." It involves blocking an initial attack and breaking the adversary's forces or warfighting capacity. The "break" phase would target not only attacking forces but also what controls and supports them. He also emphasized the alliance's military readiness.

Fox News quoted him as saying: "My theory of victory is simple: we will block the initial attack. If the attack persists, we will blunt it and prevent enemy advance." On the final phase, Fox News quoted him as saying: "This includes not just the attacking force itself, but anything and everything that supports, sustains, and controls that force." The Wall Street Journal describes the aim as breaking "the adversary's ability to control and support its forces."

The event

According to Fox News, Grynkewich spoke on Monday, the first day of the Warsaw Security Forum. The panel was titled "Theory of Victory: How Do We Achieve Military Success Against Russia in Deterrence and Defence?" Fox News reports that he did not name Russia in his address. Headlines in the Wall Street Journal and Le Monde present the strategy as directed at a Russian attack or threat.

According to Fox News, he said NATO was already applying the strategy through exercises, enhanced readiness and investment in new capabilities. He also recalled President Donald Trump's positive remarks at the 2025 NATO summit in The Hague. "I was in the room and I felt the love," Fox News quoted him as saying.

Le Monde reports that he downplayed the odds of an imminent conflict. TASS reports that he said a U.S. military base in Poland would take years to establish. The reports do not make clear whether that remark came at the same event.

Context

Fox News, citing Reuters, reports that on 30 September Russia sent NATO a diplomatic note. According to Fox News, it warned Russia could use its full arsenal, including nuclear weapons, if the alliance tried to isolate Kaliningrad.

What each side says

• Grynkewich: NATO is defensive but would fight if attacked. "If attacked, we are ready to fight tonight, but we are not complacent," Fox News quoted him as saying.
• Russian government: The note, as cited by Fox News, says NATO is pursuing a "dangerous and reckless course."
• Vladimir Putin: According to Fox News, he says Russia has no plans to attack European countries.
• NATO Secretary-General Mark Rutte: He rejected Russia's threats. "Putin knows that he can never win from NATO," Fox News quoted him as saying.
• European officials: According to Fox News, they say Russia is waging a hybrid campaign of sabotage, arson and cyberattacks.

The reports reviewed by Vocemundi do not include a full transcript of the remarks. Nearly all quotes come from Fox News. The "break" phase is described in broad categories, but the reports do not name specific targets. They do not include a Russian response to the speech.

Analysis

The speech publicly sets out how NATO's top commander says the alliance would respond if attacked. Supporters of deterrence may see such clarity as reducing the risk of miscalculation. Others may ask how far the "break" phase could extend, since Fox News quotes him defining it broadly as "anything and everything" supporting an attacking force. That question may matter for escalation risks, given the Russian note reported by Fox News. Much depends on details not yet in the reports reviewed: a full transcript, official NATO texts and any Russian reply. These could clarify whether the remarks describe existing plans or signal a change in posture.
