The lede in a Wall Street Journal article goes like this:
Western leaders are beginning to have a clearer vision of how they hope the war in Ukraine will end.
What is missing is any plan to make it happen.

Ukrainian President Volodymyr Zelenskyy has articulated that vision since the day the barbarian hordes swarmed over the borders: all Russian forces out of all Ukrainian territory. Full stop.
