US officials seek final end to Russia-Ukraine war as Abu Dhabi talks begin

US officials began trilateral talks in Abu Dhabi on Tuesday seeking a "final end" to the Russia-Ukraine war, marking the first substantive negotiations between the two countries since February and the first since US joint strikes with Israel against Iran. The Trump administration's proposal includes a new "long-term security architecture" between Russia and Europe, potentially reviving the Nato-Russia council and lifting sanctions. European officials worry Russia will demand Nato roll back its military footprint across eastern Europe, leaving allies vulnerable amid historic tensions. US negotiators, including Jared Kushner, have discussed security guarantees for Ukraine similar to Nato's article 5, though critics question what would trigger them. European delegations from Germany, France, the UK, Italy and the EU will meet US negotiators in Abu Dhabi, bracing for potential concessions to Russia.
