ROGER KIMBALL GIVES credit where credit is due. “Regular readers of this column know that I am not a paid-up member of the New York Times Book Review fan club. Quite the contrary. But, every now and then, that once-mighty organ manages to hit one out of the park, and ‘The Age of Kennan,’ the long, exquisitely thoughtful review of John Gaddis’s new biography of George Kennan by Henry Kissinger is a case in point. Secretary Kissinger’s essay is more more than a review, it is a masterpiece of intellectual and historical compression, illuminating in a few thousand words, the complex and sometimes contradictory edifice that was George Kennan’s strategic thought.”
