President Trump told reporters in the Oval Office on Thursday that "there's going to be an agreement" on Ukraine, one that will involve more than Ukraine and "might involve all of Europe." He promised a "big, beautiful agreement" that would leave everyone "thrilled." The remarks came after he privately met Kirill Dmitriev, the special envoy of Russian President Vladimir Putin, at the White House. Trump offered no details on what the agreement would contain, who would be part of it, or when it might be reached. Earlier that day, First Lady Melania Trump had hosted a rare face-to-face event with Russian and Ukrainian officials, and Trump said he had not met the Ukrainian officials who were there.

That event marked a six-day ceasefire in the Russian-held city of Oleshky, which Melania Trump helped broker and which expired on Sunday. A U.S. delegation is now scheduled to mediate talks between Russia and Ukraine in Abu Dhabi on November 10 and 11. Trump has been pressing Kyiv to reach a peace deal with Moscow, and his latest words raise big questions. What exactly would an agreement covering "all of Europe" look like, and would European governments and Ukraine accept it? For now it is a promise rather than a signed deal, and none of its terms have been made public.
