Donald Trump was not. When the leaders of Russia and the United States shook hands on stage after failing to reach a deal at their Alaska summit, President Trump had a look on his face that his four predecessors might have recognized after their own encounters with the former KGB agent who has defied the world in his determination to rebuild an empire.

After leaving Alaska, Trump says he would prefer to "go directly to a peace agreement" to end the war in Ukraine as he prepares to meet Zelensky on Monday.

President Trump and Russian President Vladimir Putin held a high-stakes summit in Alaska, but the talks did not yield a ceasefire in Ukraine.
