Putin refuses to meet Trump's ultimatum to end the Ukraine war, aiming to capture four regions.

Russian President Vladimir Putin is unlikely to meet US President Donald Trump's ultimatum to end the war in Ukraine. Putin aims to capture four Ukrainian regions and believes Russia is winning despite US sanctions. Trump threatened new sanctions and 100% tariffs on Russian oil buyers if Putin does not agree to a ceasefire. Talks between Russia and Ukraine have made little progress. Putin might consider an air truce to avoid further sanctions but remains focused on military goals.
