NATO Warns Russia: If You Attack, We Will Break Your Forces and Destroy 'Anything and Everything'

Gen. Alexus Grynkewich outlined NATO's strategy to 'block, immobilize and break' enemy forces at a security conference in Warsaw amid rising Russia tensions.

Expert: NATO should take the threat of Russia's Kaliningrad "very seriously".

Professor Azim Ibrahim says Russia's heavily militarized Baltic region has become a testing ground for hybrid warfare targeting European infrastructure.

NATO's top military commander warned on Monday that what he called a "deadly coalition" would destroy "anything and everything" that supports an attack on allied territory and "destroy" enemy combat systems to thwart any possible future Russian attack.

"If the enemy decides to press the offensive or make his reserves, we will break the war system that is stacked against us," Gen. Aleksos Grinkiewicz told a security meeting in Warsaw, Poland, in an apparent warning to Moscow.

During a panel discussion entitled "Theory of Victory: How can we achieve military success against Russia in deterrence and defense?" "This includes not only the attacking force itself, but anything and everything that supports, maintains and controls that force," he said. On the first day of the forum

Grinkovich, NATO's supreme commander in Europe, also outlined a three-pronged strategy to "block, slow and break" enemy forces, making clear that while NATO is a defensive alliance, it is prepared to respond decisively to an attack on any of its 32 members.

"If someone is stupid enough to attack us, we will fight," he said. We will stop the attack and deny them the ability to achieve their goals, whatever they are. In short, we will ensure that any attack, against any ally, will be completely futile."

The warning came amid heightened tensions between Russia and Western countries following a series of drone attacks and suspected sabotage operations that European countries have linked to Moscow.

"Today, here in Poland, we stand together stronger than ever in our shared vision for a more balanced, ready and lethal alliance," Grinkiewicz also said.

European officials have accused Russia of waging a hybrid war involving sabotage, arson and cyber attacks, along with increasingly provocative military activities near NATO territory.

In 2025, several Russian drones entered Polish airspace during a massive attack on Ukraine, prompting a response from Polish and allied aircraft.

NATO launched Operation Eastern Guard to strengthen defenses along its eastern flank.

Romania has also reported Russian drone strikes, while Estonia has accused Russian military aircraft of violating its airspace.

Grinkovich's comments came after a tense week between Russia and Ukraine, with Moscow launching new attacks on Ukraine's energy infrastructure despite diplomatic efforts to ease hostilities.

US President Donald Trump announced that he and Russian President Vladimir Putin have reached an agreement to increase the supply of Russian diesel to the US and global markets.

The reported deal included exemptions from some US sanctions on Russian energy exports.

Zelensky went on to accuse Russia of continuing attacks on Ukrainian energy facilities and cast doubt on the prospect of a broader ceasefire.

These tensions have also been accompanied by Moscow's recent nuclear warnings.

On September 30, Russia warned NATO that it could use nuclear weapons if the alliance tried to isolate Kaliningrad, its heavily militarized enclave on the Baltic Sea between Poland and Lithuania.

According to the memo, Russia warned that it could use its full military arsenal, including nuclear weapons, to defend Kaliningrad, raising the possibility of attacking decision-making centers in NATO countries early in the conflict.

NATO Secretary General Mark Rutte dismissed the threats, emphasizing the alliance's defense mission and calling on Moscow to end its war in Ukraine.

"Putin knows he can never win from NATO," Rutte said at the Euronews Defense and Space Summit on September 30.

Putin has also emphasized that Russia has no plans to attack European countries and wants peaceful coexistence with its neighbors.

Grinkovich did not mention Russia during his time in Warsaw, but his warning was aimed at Moscow, and with NATO's 2022 strategic concept, he introduced Russia as the most important and direct threat to the allies' security.

"My theory of victory is simple: We stop the initial attack. If the attack continues, we slow it down and stop the enemy from advancing," Grinkovich said Monday.

And if necessary, we will break the enemy's forces and the operational system of war that is arranged against us.

NATO has already implemented this strategy through military maneuvers, increased military readiness and investment in new capabilities, Grinkovic said.

"If attacked, we are ready to fight tonight, but we are not satisfied," he said.

The general clarified that NATO's response would not necessarily be limited to enemy forces directly involved in an attack, but could extend to the broader military infrastructure that enables an attack.

Meanwhile, Trump has pressed European allies to increase defense spending and questioned whether countries that default should expect American support.

Grinkovich sought to downplay concerns about Washington's commitment, recalling Trump's positive comments about the alliance during the 2025 NATO summit in The Hague, Netherlands.

"I was in the room and I felt the love," Grinkovich said of the 2025 event.

"What I want to do is to reassure the billions of citizens of our alliance that we have this. We know what we have to do. We know how we're going to do it."

He also indicated that he would be willing to speak more openly about suspected hybrid attacks if NATO governments wanted him to address their concerns.

"If a nation asks me, I'm happy to talk about it," he said.
