The European leaders in the State Dining Room were there to manage a global crisis. Which meant they also had to manage the mood of one famously mercurial man. The subject of this high-level diplomatic summit was diplomacy mixed with psychology.
Adding to the surreal nature of the thing was the way that President Vladimir V. Putin of Russia hovered over it all, just out of sight, like a character offstage. Mr. Trump kept bringing up Mr. Putin’s perspective. “Vladimir Putin wants it to end,” he claimed. He repeatedly mentioned that he needed to call Mr. Putin to update him on how the meetings were shaping up.
The Europeans looked stoic at every mention of Mr. Putin, as though they hardly needed to be reminded of the Russian leader’s viewpoint.
