United States | September 26, 2025—In a stunning about-face, President Donald Trump has reversed his long-standing stance on the war in Ukraine, declaring that Kyiv can—and should—reclaim all territory lost to Russia. The announcement, made during the United Nations General Assembly and amplified on Truth Social, marks a dramatic shift from Trump’s earlier calls for Ukrainian concessions and a swift diplomatic resolution.

“Ukraine, with the support of the European Union, is in a position to fight and WIN all of Ukraine back in its original form,” Trump posted. “With time, patience, and the financial support of Europe and, in particular, NATO, the original borders from where this war started is very much an option.”

From Concessions to Combat

Just months ago, Trump had told Ukrainian President Volodymyr Zelenskyy in a tense Oval Office meeting that Ukraine lacked the leverage to challenge Russia militarily. Now, following a more cordial meeting in New York, Zelenskyy says he was “very surprised” by Trump’s rhetorical pivot.¹

Behind closed doors, Trump reportedly expressed frustration with Russian President Vladimir Putin, citing battlefield losses and alleged deception. Vice President JD Vance later clarified that the shift was “an acknowledgment of the reality on the ground,” not a wholesale policy change.^{2 3}

Mixed Signals and Market Ripples

While Kyiv greeted the reversal with cautious optimism, Moscow responded with mockery. Kremlin spokesman Dmitry Peskov dismissed Trump’s characterization of Russia as a “paper tiger,” retorting, “Russia is a real bear”.⁴

Meanwhile, global markets reacted swiftly. Defense stocks surged across Europe and Asia, reflecting investor anticipation of increased military spending and potential new contracts.⁵

Allies Wary, Experts Skeptical

Despite the bold rhetoric, NATO allies remain wary. European diplomats warned that Trump’s statements may reflect the influence of recent conversations rather than a durable strategic shift. “It’s great to put that pressure on the Russians—for now—until the administration decides something else,” one Brussels-based official said.²

Security experts echoed the concern. Former CIA Moscow station chief Dan Hoffman cautioned that Putin is unmoved by words alone. “He wants to show Ukraine the United States doesn’t have the ability to project power in that part of the world,” Hoffman said.⁶

What Comes Next?

Zelenskyy has requested new weapons systems to counter Russian infrastructure strikes, though Trump has yet to commit publicly. The president emphasized that U.S. weapons would continue flowing to NATO “for NATO to do what they want with them,” sidestepping direct pledges to Ukraine.⁴

As the war enters its fourth year, Trump’s reversal injects fresh uncertainty into an already volatile geopolitical landscape. Whether this shift leads to tangible support—or proves another rhetorical detour—remains to be seen.
