Spy Vs. Spies: Why Deciphering Putin Is So Hard For U.S. Intelligence

American intelligence officers are trained to tackle tough targets.

But there are tough targets, and then there's Russian President Vladimir Putin, who plays his cards so closely that it's hard for his own advisers to divine what he's thinking, says Gregory Treverton, chairman of the National Intelligence Council.

"Putin is so isolated that the chances that he might miscalculate and do something rash are top of my list for things I worry about," says Treverton. "I am fond of distinguishing between puzzles — those things that have an answer, though we may not know it — and mysteries, those things that are iffy and contingent. And so how Putin is going to behave is presumably a mystery, and probably even a mystery to Putin."
