Ahead of the Trump-Putin summit in Alaska, a Chatham House analyst is saying Ukraine will not accept any deal imposed without its participation. U.S. President Donald Trump and Russian President Vladimir Putin are expected to discuss a possible deal to end the war in Ukraine when they meet on Friday. Jaroslava Barbieri, Research Fellow at the Ukraine Forum at Chatham House, points out that Trump has said any peace deal would involve "some swapping of territories to the betterment of both" Russia and Ukraine, prompting consternation in Kyiv and European capitals as virtually all the territory in question is Ukrainian.
