There’s only one person who’ll be genuinely pleased with the Intelligence and Security Committee’s Russia report, finally revealed on Tuesday, and that’s Vladimir Putin. Russia emerges as an amorphous and formidable enemy — all the more so because the inconclusive and much-redacted report contains next to no substantiated allegations. Instead Russia appears as a phantom, unknowable menace, and this will spawn a thousand conspiracy theories far more corrosive and confusing to our politics than any Moscow–generated Twitter-storm or document leak.
