But Tusk had a different take on Trump’s apparent U-turn. Reading between the lines, the U.S. president was seemingly backing away from his pledge to end the conflict, the Polish leader warned Thursday.

“President Trump has stated that Ukraine could, with the support of the European Union, regain all of its territory. This surprising optimism conceals a promise of reduced U.S. involvement and a shift of responsibility for ending the war to Europe,” Tusk wrote on social media. “Truth is better than illusion.”

Trump has previously threatened to walk away from negotiations between Ukraine and Russia, and has admitted the war is proving more difficult to end than he expected — though he shocked Western allies with Tuesday night’s missive.

“I think Ukraine, with the support of the European Union, is in a position to fight and WIN all of Ukraine back in its original form,” he wrote on social media shortly after a meeting with Ukrainian President Volodymyr Zelenskyy on the sidelines of the United Nations General Assembly.

“We will continue to supply weapons to NATO for NATO to do what they want with them. Good luck to all!” he added.

His whiplash-inducing pivots on the conflict, from denouncing Russian President Vladimir Putin as “absolutely CRAZY” to embracing him at a summit in Alaska a few months later, or pausing, then restarting delivery of military aid to Ukraine, have left Kyiv and its allies anxious about where Washington really stands.

Regnier took aim at specific platforms in his remarks, stating that for example in Germany, “TikTok is used by half of children between 6 and 13 … That’s even below the legal threshold established by TikTok in their terms and conditions.”

Paolo Ganino, head of policy communications for TikTok in Europe, said in response that the site removes “around 6 million underage accounts globally each month” as part of a “broader trust and safety programme … designed to support the safety and well-being of teens and families.”

Amid vocal concerns from the U.S. government and tech companies about the implications of the EU’s content rules on civil liberties and free speech, Regnier said: “We will not, as a public institution, decide what social media our citizens can use. This is not our role. We take the problem the other way around. We want companies to follow our rules to make sure our citizens can use it in a safe way.”

Regnier stressed the Digital Services Act “is not the legal basis that will allow us to set the minimum age.”

European governments have increasingly been rallying behind strongly enforcing age limits on social media, whether pushing for national action or backing a bloc-wide crackdown.
