Ukrainian President Volodymyr Zelenskyy has issued a stark warning to the international community after former U.S. President Donald Trump confirmed plans for a private, in-person meeting with Russian leader Vladimir Putin. Speaking during a televised address streamed on the Ukrainian president’s official website, Zelenskyy said such talks could “reshape the battlefield” and carry “grave consequences” for both Ukraine and NATO allies. His tone was uncharacteristically grim, describing the upcoming meeting as “a moment that could decide the future of Europe.”
Trump’s announcement came during a rally in Pennsylvania, where he told supporters that his meeting with Putin would be aimed at ending the war in Ukraine “in 24 hours.” He offered no specifics on how such an agreement could be reached, but emphasized that it would be conducted “man-to-man” without advisers present. The remarks were later amplified in a video posted on Truth Social, where Trump claimed he could “cut through the nonsense” of traditional diplomacy.

For Zelenskyy, the idea of a closed-door meeting between Trump and Putin is not just political theater — it’s a potential national security nightmare. “When someone speaks privately with Putin, without transparency, without the world knowing what is said, we must ask ourselves: what promises will be made, and at whose expense?” Zelenskyy said, his voice tightening. He urged the U.S. Congress and the Biden administration to “safeguard the principles of the free world” ahead of the talks.

Behind the scenes, diplomatic sources told the Financial Times that Kyiv has already reached out to European capitals to coordinate a unified response if Trump’s meeting leads to concessions on territory or sanctions. One EU official called the situation “deeply concerning,” adding that Trump’s previous praise of Putin during his presidency has only heightened fears in Ukraine.
Putin’s spokesman, Dmitry Peskov, confirmed to Interfax that the Kremlin welcomed Trump’s proposal and was “ready to arrange a mutually convenient location” for the talks. Russian state television has already begun framing the meeting as a “historic turning point” that could bypass current Western leadership, airing montages of Trump shaking hands with Putin during the 2018 Helsinki summit.
In Washington, reaction was swift and divided. Several Republican lawmakers praised the move, with one telling Fox News that “real diplomacy requires bold moves.” Meanwhile, Democrats slammed the idea as reckless, with Senator Chris Murphy warning on MSNBC that “Putin doesn’t attend meetings without extracting something in return.”
National security analysts are voicing similar concerns. Retired Lt. Gen. Ben Hodges told BBC News that any private agreement could undermine existing military aid arrangements. “If Trump tells Putin something that suggests U.S. support is weakening, that signal could be catastrophic on the battlefield,” Hodges said.

Complicating matters is the timing: the meeting is reportedly scheduled just weeks before a critical NATO summit in Brussels, where member states are set to finalize long-term defense commitments for Ukraine. Diplomats fear that if Trump strikes an informal understanding with Putin beforehand, it could weaken the alliance’s negotiating position.
