In his much-commented 60 Minutes interview this week, Donald Trump breezily dismissed the idea that accepting information on political rivals from foreign sources was untoward. “It’s not an interference, they have information,” he said. “I think I’d take it. If I thought there was something wrong, I’d go maybe to the FBI.” Thus the man who routinely indulges in the fantasy that a collective of American spies is arranging his downfall has no compunction about letting foreign spies arrange the downfall of his opponents. It all depends on what gifts they come bearing. But the trouble with inviting foreign countries into your political system is that once they accept the invitation they never leave. A new study I’ve co-edited, published by the Free Russia Foundation, offers a chilling tour d’horizon of how the Kremlin has walked right into the judiciaries, interior ministries, ballot boxes, campaign coffers and even spy services of Europe, all because domestic politicians initially waved them in. The broad conclusion of “Misrule of Law,” as the report is titled, is that instead of a Europe whole and free, we’ve got one partly subsidized and dangerously subservient to Vladimir Putin.
