Starlink restrictions hampering Ukraine’s war effort are “a planned operation,” Ukrainian President Volodymyr Zelenskyy said on Saturday.

The satellite service operated by Elon Musk’s SpaceX is still deactivated in Ukraine at speeds over 160 km/h, which prevents some of its drones to intercept high-speed Shahed drones used by Russia, Zelenskyy told reporters in a WhatsApp chat.

He added that Ukraine conducted a test by sending Starlink-equipped vehicules to European Union countries, at speeds over 180 km/h. “Starlink kept working … The conclusion is this: the restrictions are in effect in Ukraine, but they are not in effect in European Union countries. So, this is a planned operation,” Zelenskyy said.

The restrictions have revived questions on Ukraine’s reliance on the satellite system operated by a U.S. company amid escalating tensions between Kyiv and the White House. “This will cost many of us our lives,” an experienced Ukrainian officer told POLITICO and the Axel Springer Global Reporters Network earlier this week.

“We’re reaching out to everyone at the military level, at the Ministry of Defense level, and at the diplomatic level, including to SpaceX. Right now, no one is responding to our military or the Ministry of Defense,” Zelenskyy told reporters.

The European Union is under increasing pressure to provide Ukraine with an alternative to Starlink. But negotiations between Brussels and Kyiv over access to the bloc’s Govsatcom program — which gives participating governments secure communications capabilities— have been stalling. And IRIS², the EU’s in-house planned network to match Starlink, is only expected to come online in 2030.

“The Europeans are now raising the question of alternatives themselves. And they’re already working on them. They’re already making progress, and they’ll succeed in this area. I can already see that,” Zelenskyy said.

SpaceX did not immediately responded to a request for comment.

Earlier on Saturday, Zelenskyy accused Russia of looking to create a blackout across Ukraine, amid attacks on energy infrastructure and the waiver of U.S. sanctions on Moscow.

“Russia is trying to cause a blackout in Ukraine right before winter. Russia is trying to leave millions of our people without electricity and heating. Pressure is needed to stop this,” he said on Telegram.

“An American sanctions blackout, easing pressure on the aggressor, monetary rewards for [Russian President Vladimir] Putin: all of this only encourages him to keep striking,” he added.

The Ukrainian leader’s comments come after Russia carried out strikes on the war-torn country’s energy sector, including power generation and transmission facilities, with more than 320 jet-powered Shahed drones, loitering munitions, cruise and ballistic missiles. Power was reportedly cut for about 1 million people.

They also come as U.S. President Donald Trump signed on Friday an executive order that waived key sanctions on Russia — a decision that Kirill Dmitriev, Putin’s special envoy for investment and economic cooperation, described as “an important and truly historic moment.” Trump’s move comes only a few days after he made a deal with Putin over supplying barrels of diesel, leaving European countries and Ukraine stunned.

“A decision was unfortunately made in America to completely ignore Lindsey Graham’s bill, which was supposed to introduce truly effective pressure on Russia to end this war,” Zelenskyy said. “This bill could have helped a great deal, and it still can! But the law needs to actually work, and every vote for it matters.”

NATO’s top commander U.S. Gen. Alexus Grynkewich on Monday vowed to block, blunt and break any Russian attack as part of a new “Theory of Victory,” and underlined that alliance troops would fight even if U.S. forces were engaged elsewhere.

Speaking at the Warsaw Security Forum, Grynkewich outlined how the 32-member alliance would respond to an invasion of NATO territory as concerns grow that Russia could be capable of attacking a NATO member by the end of the decade.

“Our alliance exists to preserve peace,” he said, “but let there be no doubt: should war come, we will block, blunt any attack, and then, if it does not cease, we will break the forces conducting aggression against us.”

The rare intervention by the four-star general to discuss a military blueprint underscores NATO’s effort to deter Russia. It is also aimed at sending a message of NATO unity after a grueling year for the alliance, which was rocked by Donald Trump’s threats to annex Greenland and infighting over the U.S.-Israeli war in Iran.

Under the three-part blueprint, NATO would initially use land-based troops — buttressed by air, naval, cyber and space capabilities — to stop an assault, targeting attacking forces and preventing them from seizing territory, Grynkewich said.

NATO would then use sensors and autonomous systems among other capabilities to “overwhelm enemy formations … and their advance,” he said, before using “highly effective precision munitions” and unmanned systems if necessary to “break the [enemy] warfighting system” and “everything that supports” it.

Lithuanian Defense Minister Robertas Kaunas said the theory laid out by Grynkewich “will send a strong message to our adversaries that we are going to defend ourselves.”

NATO’s Supreme Allied Commander Europe said he does “not assess that conflict is imminent or inevitable.” But “we will … ensure any attack against any ally proves utterly futile.”

The speech describes a more forceful response if a foe attacks, but its credibility depends on allies having the forces, infrastructure, and coordination to implement the plan.

Asked whether the plan factored in a scenario where the U.S. was engaged elsewhere, Grynkewich said: “It absolutely does account for that, and in fact, it must.”

Under Trump, the U.S. has sought to refocus its military on other priorities such as the Indo-Pacific, homeland security and the Western Hemisphere. U.S. ambassador to NATO Matthew Whitaker said in Warsaw on Monday that Europe only ranks fourth among Washington’s strategic concerns.

The Pentagon has already cut its contributions to NATO crisis forces and is set to unveil a review of U.S. forces in Europe by the end of the year.

“No one should question the commitment of the United States to this alliance,” Grynkewich argued, but added that “ultimately, it’s a political decision about who’s providing troops where.”

Camille Grand, NATO’s former assistant secretary-general for defense investment, said the plan was “a very deliberate effort” to signal that the alliance would be ready to fight with or without large-scale involvement of U.S. forces.

“For my country, fighting with Russians is with or without Americans,” said a separate senior European defense official, who was granted anonymity to speak freely. “We expect them to come, but if they won’t, we will fight anyway.”

Grand added that the blueprint is also an indication that NATO is ready to take a bolder approach toward Moscow by threatening the destruction of its war machine even deep behind the front lines.

That comes as Moscow sent a letter to NATO last month threatening to use its nuclear arsenal if the alliance tried to isolate its Kaliningrad exclave.

Grynkewich warned that NATO would be ready to respond — even with its nuclear arsenal.

“Should an adversary threaten escalation by saber-rattling, or should one actually decide to escalate during conflict, it will not fracture our alliance,” he said. “We should take comfort in our ability to deliver mass effects and the implicit warning that we could match any enemy move up the escalation ladder.”
