Donald Trump’s second term began with his inauguration on January 20, 2025, and there was no peace treaty or formal end to the Russia‑Ukraine war on that day or in the weeks immediately following; instead, the war continued and only later did talks about a temporary ceasefire emerge. (en.wikipedia.org) Reporting on Trump’s early Ukraine diplomacy notes that his promised 24‑hour resolution did not occur and that an initial U.S. proposal tied to aid and economic arrangements went unsigned by Kyiv because Zelenskyy judged it unacceptable and said he could not “sell Ukraine away,” indicating a refusal to accept the demanded terms. (en.wikipedia.org) Throughout early and mid‑2025, Zelenskyy repeatedly and publicly ruled out territorial concessions as the price of peace or a ceasefire, stating that Ukraine would not recognize occupied land as Russian and would not give up territory under any circumstances. (eadaily.com) As of late 2025, Ukrainian officials still insist they will not cede territory even though draft peace plans from the U.S. and Russia explicitly require Ukraine to surrender land, underscoring that Kyiv has not been willing to make the key concessions Trump and Moscow have sought. (theguardian.com) While Russia’s own maximalist demands are also a major obstacle, the specific claim that Trump could not end the war on “day one” because Ukraine was not yet prepared to make the concessions his kind of deal would require is well supported by the subsequent record, so the prediction is best judged as right.
