U.S. special envoy Steve Witkoff said Sunday that President Donald Trump and Russian President Vladimir Putin agreed during their summit in Alaska on a framework to grant Ukraine “robust security guarantees.” In a CNN interview, Witkoff described the prospective commitments as “game-changing,” adding that the United States and several European nations could extend Article 5-style protections to Kyiv outside the NATO treaty structure. Witkoff also claimed Moscow offered concessions involving five Ukrainian regions and pledged not to pursue additional territorial claims once a peace accord is formalised. He did not specify which regions were discussed or outline enforcement mechanisms, and said the language would be legislated both in the United States and in Russia. The Kremlin, NATO and the Ukrainian government have yet to confirm the reported breakthrough. Trump is scheduled to meet Ukrainian President Volodymyr Zelensky in Washington on Monday alongside European leaders including France’s Emmanuel Macron and Germany’s Friedrich Merz. The gathering is expected to review the Alaska proposal and wider military and economic support for Ukraine.
