<h1>U.S. proposes direct Russia-Ukraine summit to negotiate war end while backing European security guarantees without combat troops</h1> The U.S. president announced steps to arrange a face-to-face meeting between the Russian and Ukrainian presidents to negotiate an end to the war, while affirming U.S. support for European security guarantees to deter reinvasion. Details remain unsettled, including whether Russia has agreed, whether a ceasefire will precede talks, and whether guarantees will involve troops or a 'NATO-like' presence; the U.S. stopped short of pledging combat forces. European leaders signaled support for guarantees and warned of strengthened sanctions if negotiations fail. The proposal raises legal and diplomatic issues about territorial concessions, enforcement of guarantees, and the status of previously annexed territory.
