Peace in Ukraine remains as elusive as when Russian tanks first streamed across its borders more than three years ago. This week’s talks in Istanbul—talks that Vladimir Putin himself proposed—show he isn’t yet ready to do a deal.

Trump said he will speak to the Russian president, who recently skipped peace talks with Ukraine, on Monday morning.

Trump has repeatedly claimed that he will end the war, initially promising that he would stop the fighting in Ukraine before even taking the oath of office.
