More than 80 years after the Yalta conference reshaped post-war Europe, some observers fear a new era of great-power diplomacy could once again shape the continent's future. Reports of a possible meeting between Donald Trump, Vladimir Putin and Xi Jinping have prompted questions about what role Ukraine would play in any discussion about ending the war. 
The speculation comes amid a sharp deterioration in relations between Washington and Kyiv. From disputes over Starlink access to growing concerns about Trump's outreach to Moscow, Ukrainian officials worry they are losing influence with their most powerful ally. 
At the centre of the debate is a simple question: does Trump see Ukraine as an indispensable partner, or an obstacle to broader deals with Russia? 
The Global Story’s Tristan Redman speaks to Simon Shuster of The Atlantic about the state of the war, the future of US support and why Kyiv is increasingly worried about being left out of the room.
