By now, the basic facts of the case appear largely settled: hackers working in coördination with—or on direct orders from—Vladimir Putin’s government broke into the e-mail accounts of the Democratic National Committee and John Podesta, Hillary Clinton’s campaign chairman, passing the contents to WikiLeaks, which published them in slow drips over the summer and fall. Clinton, of course, lost last month’s Presidential election; Democrats quickly seized on the hacks, and the media coverage of them, to help explain the outcome. Anonymous sources at the C.I.A.—and, later, the F.B.I. and other intelligence agencies—told the Washington Post that aiding Trump’s candidacy was exactly the point of the Russian operation. Yet many important questions remain unanswered. What was the ultimate effect of the Russian hacks? Why did the Russians do it, and how, in his final days in office, should Barack Obama respond?
