Vladimir Putin wanted a lot of things from his visit to Alaska. A ceasefire in Ukraine was not one of them. Throughout the summer, his troops have been grinding out advances along the frontline, and they achieved a sudden breakthrough in the days before the Alaska summit.

The push for a bilateral meeting comes after the US president met Putin in Alaska last week, and welcomed seven European leaders and Zelensky to the White House on Monday. Trump admitted the conflict was "a tough one" to solve and conceded it was possible the Russian president was not interested in ending hostilities.
