A nation must think before it acts.
President Trump arrived Sunday in Helsinki in the manner of most of his predecessors: with little awareness of recent Russian history and in apparent confusion about what a meeting with Vladimir Putin can achieve. Reacting to concerns about Mr. Putin’s career in Russian intelligence, Mr. Trump said at a recent rally: “Putin’s fine. He’s fine. We’re all fine. We’re people.” According to a news report, White House advisers describe the Trump-Putin meeting “as a chance to reset a tense relationship.”
