President Donald Trump said on 15 Aug that the United States could "maybe" extend security guarantees to Ukraine together with European partners, but "not in the form of NATO," leaving open the possibility of a new, ad-hoc framework outside the Atlantic alliance. Trump’s remarks follow a 13 Aug conference call with European leaders that was first reported by Politico and publicly confirmed by French President Emmanuel Macron. According to Macron, Trump told the leaders that the United States and “all willing allies” should participate in any future security architecture for Kyiv, while explicitly ruling out NATO’s formal involvement. Trump offered no timetable or operational details, and diplomats said the guarantees would likely be considered only as part of a final peace agreement. The U.S. president added that he might meet Russian President Vladimir Putin to discuss Ukraine and broader business issues if “progress” is achieved, warning the encounter "could have severe consequences." The comments underscore Washington’s search for alternative security arrangements for Ukraine as the war enters its fourth year and NATO membership remains off the table.
