Ukraine’s President Volodymyr Zelensky might meet Russia’s President Vladimir Putin in Turkey on Thursday – if the Russian leader decides to show up for a summit that he himself suggested.

What will unfold remains unclear. The Kremlin has refused to confirm who’s going to Turkey and whether it will include Putin. Ukrainian presidential adviser Mykhailo Podolyak said Zelensky will only sit down with the Russian leader.

Each side is seeking to call the other’s bluff by demonstrating they alone want peace while the other is the obstacle.
