Zelenskyy escalates rhetoric as Ukraine strikes Moscow; NATO reviews European posture

Ongoing war in Ukraine continues with escalating military strikes on civilian infrastructure and calls for nuclear weapons use.
If Ukraine burns, your Moscow will burn.
Zelenskyy's warning after overnight drone strikes on Russian refineries, signaling Ukraine's willingness to escalate while demanding Western economic pressure on Russia.

On the evening of June 18th, Ukrainian President Zelenskyy arrived in Brussels carrying both a warning and a plea — that the war consuming his country would not be contained by borders alone. As Ukrainian drones struck Moscow's oil infrastructure for the second time in a week, Western leaders gathered to speak of 'new momentum' and historic negotiations, even as the deeper question of who bears the burden of this conflict — and for how long — remained unresolved. The summit revealed not a unified alliance but a shifting architecture of responsibility, with the United States pressing Europe to stand more fully on its own, and Ukraine pressing everyone to understand that its survival is inseparable from theirs.

  • Zelenskyy's declaration that Moscow will burn if Ukraine does marks a deliberate escalation in rhetoric, signaling that Ukraine will no longer absorb Russian aggression without mirroring its consequences.
  • Ukrainian drone strikes on Moscow's oil refineries twice in one week have forced the world's third-largest oil producer to import fuel by sea, exposing the real fragility beneath Russia's wartime posture.
  • US Defence Secretary Hegseth's blunt accusation that NATO is a 'paper tiger' and a 'one-way street' has injected urgency into European capitals, with Poland and Lithuania racing to secure permanent American troop deployments before the review reshapes the alliance.
  • Russian hardliners are openly calling for nuclear retaliation on state platforms, while the Kremlin devotes nearly half its budget to defence — a pressure that NATO's secretary general describes as economically 'crazy' but strategically unresolved.
  • The summit's optimism about Ukraine's accession and Western solidarity rests on a fragile condition: that European support remains sustained, consistent, and sufficient — a condition no one at the table can fully guarantee.

Volodymyr Zelenskyy arrived at the European Council summit in Brussels on June 18th with a warning still reverberating from the night before. 'If Ukraine burns, your Moscow will burn,' he had told reporters, his words sharpened by overnight drone strikes that had hit the Russian capital's oil refinery for the second time in a week. Beyond the military message, Zelenskyy was making a demand: that Europe and the United States tighten sanctions on Russia's defence and energy sectors, and understand that Ukraine would not absorb escalation alone.

In Brussels, Western leaders spoke of 'new momentum.' European Council President António Costa called it a historic week, with formal accession negotiations underway and G7 support reaffirmed. Ursula von der Leyen declared the tide was turning. The diplomatic language was optimistic — Ukraine was holding, Russia was straining economically, and the narrative of Western capitals was one of resilience against attrition.

But a harder reckoning ran beneath the surface. US Defence Secretary Pete Hegseth delivered blunt assessments of NATO's posture, calling the alliance a 'paper tiger' and accusing European members of free-riding on American security. He announced a comprehensive review of US force positioning in Europe, making clear it would carry real consequences. Poland and Lithuania moved quickly to secure permanent American deployments on their soil, with Warsaw's defence minister reporting a positive US response and Donald Tusk saying things were moving faster than expected.

The human cost of the war remained relentless. Ukraine and Germany signed an agreement on anti-ballistic capabilities, and Zelenskyy pressed urgently for long-range artillery and unmanned systems before winter. US Undersecretary Elbridge Colby acknowledged that Europe had stepped up, but warned that Ukraine's defensive position could only hold with continued, sustained support — a condition that left an unspoken fragility in every commitment made.

In Moscow, the strikes had provoked calls for nuclear retaliation from hardliners on state platforms, while Russia's economy bent under the weight of war — importing fuel by sea and spending nearly half its state budget on defence. NATO Secretary General Mark Rutte offered a measured but sobering frame: Putin would eventually have to decide whether to negotiate, but until then, the West's task was simply to keep Ukraine as strong as possible. The war would continue. The repositioning would continue. And the question of how long this could be sustained, and at what cost, hung quietly over every handshake in Brussels.

Volodymyr Zelenskyy arrived at the European Council summit in Brussels on the evening of June 18th with a stark warning still echoing from the night before. "If Ukraine burns, your Moscow will burn," he had declared in a voice message to reporters, his rhetoric sharpened by the overnight drone strikes that had torn through the Russian capital for the second time in a week. The attacks had found their mark again—Moscow's oil refinery, a target Ukraine has learned to hit with precision. But Zelenskyy's words carried a different weight than military communiqués. They were a statement of resolve, and a demand. He called on Europe and the United States to tighten the economic noose around Russia, pushing sanctions deeper into the defence and energy sectors, into the broader machinery of Putin's economy. "We don't want this war, we never did," he said, almost as an aside. "Everyone knows it. Our partners know it." The message was clear: Ukraine did not choose escalation, but it would not absorb it alone.

In Brussels that same evening, the mood among Western leaders tilted toward what they called "new momentum." António Costa, the European Council president, greeted Zelenskyy as he arrived, flanking him alongside Ursula von der Leyen of the European Commission. Costa called it "a historic week for Ukraine"—formal accession negotiations had begun, and the G7 had pledged what they described as "clear and strong support." Von der Leyen echoed the optimism, noting that "the tide is turning." Ukraine was holding the line, even clawing back territory in places. Russia, by contrast, was struggling. Its economy was suffering. Digital censorship was tightening. The narrative of Western capitals was one of Ukrainian resilience and Russian strain.

Yet beneath the diplomatic language lay a harder calculus. US Secretary of Defence Pete Hegseth had spent the day delivering blunt assessments of NATO's posture. He called the alliance "a paper tiger and a one-way street," accusing European members of becoming dependent on American military might and of "free riding" on US security guarantees. His criticism sharpened when he addressed the refusal of some NATO allies to support American strikes in Iran—"shameful," he called it. But Hegseth was not merely venting. He announced a comprehensive review of US force positioning across Europe, one he made clear would not be ceremonial. "It's a review that some countries will fail and others will pass with flying colours," he said. The message was unmistakable: NATO would be restructured around the principle that Europe must take primary responsibility for its own defence. "Where other allies do not spend with urgency, our dues, contributions will go down. NATO will be a two-way street."

Poland and Lithuania heard this language and moved quickly. Both nations saw in Hegseth's review an opening to secure what they had long sought: permanent US military deployments on their soil. Poland's defence minister, Władysław Kosiniak-Kamysz, announced after meeting Hegseth that the US had responded positively to the proposal. No final decision had been made, but the trajectory seemed clear. Poland's Donald Tusk, arriving at the summit, told reporters the process was moving faster than expected and things were "on the right path." Lithuania's government had already added the pursuit of increased US troop presence to its formal programme.

Meanwhile, the human cost of the conflict continued to mount in ways both visible and obscured. Ukraine and Germany signed an agreement on anti-ballistic capabilities, with Zelenskyy calling urgently for long-range artillery and unmanned vehicles to be delivered by winter. The war was not abstract—it required constant replenishment of weapons, constant infusions of Western support. US Undersecretary of Defence Elbridge Colby stressed this reality to his European counterparts. The shift of primary responsibility for Ukraine's support to Europe had worked, he argued. European allies had stepped up financially and militarily. But this transition, he warned, could only hold if sustained. "Ukraine's defence does hold, but continued and sustained support from allies is essential to maintain it," he said. The implication hung in the air: if Europe faltered, Ukraine's position would crumble.

In Moscow, the overnight strikes had triggered a different kind of response. Russian hardliners demanded retaliation. Konstantin Malofeev, an ultraconservative billionaire, posted on Telegram asking why Russia was not using nuclear weapons. Andrey Gurulyov, a retired general and state Duma deputy, called for Russia to "strike the enemy mercilessly." Russia itself was beginning to feel the economic weight of the war—the world's third-largest oil producer was now forced to import fuel by sea to manage shortages caused by Ukrainian attacks on refineries. The Kremlin was spending up to 48 percent of its state budget on defence, figures that NATO Secretary General Mark Rutte called "crazy numbers."

Rutte, speaking at the summit, offered a measured assessment of the path forward. Putin "one day has got to take a decision whether he wants to play ball or not," he said. In the meantime, the West's task was clear: keep Ukraine as strong as possible in the fight. NATO itself was strong, Rutte insisted, and would make clear to Russia that any attempt to attack the alliance would be "their biggest mistake." But the subtext was one of prolonged competition, not imminent resolution. The war would continue. The support would need to continue. The repositioning of American forces across Europe would continue. And somewhere in the calculation of every Western leader present was the question of how long this could be sustained, and at what cost.

Why does Zelenskyy's warning—"if Ukraine burns, your Moscow will burn"—matter more than the usual rhetoric of war?

Model

Because he's not threatening escalation for its own sake. He's saying Ukraine has already absorbed the fire. The drones hitting Moscow twice in a week are a response, not an opening move. He's telling the West: we're doing this ourselves, but we need you to finish it through sanctions.

Inventor

The EU leaders are talking about "new momentum" and "the tide turning." Is that real, or diplomatic theater?

Model

It's both. The accession negotiations are genuinely starting—that's concrete. But the "tide turning" language masks something harder: they're betting everything on sustained European military support because the US is signaling it's stepping back. That's not momentum. That's a shift in burden.

Inventor

Hegseth keeps calling NATO a "paper tiger" and a "one-way street." What does he actually want?

Model

He wants Europe to spend more, faster, and to take primary responsibility for its own defence. The review he announced isn't an audit—it's a restructuring. Some countries will get permanent US bases. Others won't. It's leverage dressed up as strategy.

Inventor

Poland and Lithuania are both pushing for permanent US troops. Why now?

Model

Because they understand what Hegseth is really saying. If Europe has to lead its own defence, then the countries closest to Russia need to be the strongest. A permanent US base isn't just military—it's a guarantee that America won't leave them exposed.

Inventor

What about the Russian hardliners calling for nuclear weapons? How serious is that?

Model

It's a pressure valve. They're frustrated because the war isn't going as planned, and they're demanding Moscow "fight for real." But the fact that they're making these arguments publicly suggests the Kremlin hasn't shut them down. That's a sign of internal strain, not strength.

Inventor

Is there any path to peace in this conversation?

Model

Rutte said it plainly: Putin has to decide if he wants to "play ball." Until he does, the West's only move is to make sure Ukraine stays strong enough that perpetuating the war becomes too costly. That's not a path to peace. That's a path to exhaustion.
