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.

In an effort to halt the escalating violence, President Trump plans separate discussions with Vladimir Putin and Volodymyr Zelenskyy this week.
