After the damp squib of a summit with Russian president Vladimir Putin, Trump said that it was up to Putin and Ukrainian president Volodymyr Zelenskyy to work things out between them. It was never clear that Putin had agreed to such a meeting and it seems unlikely that he would. Then it was announced that Trump would meet with Zelenskyy at the White House tomorrow (Monday) again with no clear statement about what purpose it would serve, other than perhaps to tell Zelenskyy that he had better make a deal with Putin that gives up territory that Russia has already seized. He could just have easily conveyed that through other channels.
The map of the current state of affairs is below and the mood in Ukraine is strongly against such concessions.
