Read a long review in the 5/24/2012 London Review of Books by Jackson Learse about the biography of George Kennan called George Kennan by a Yale professor named George Lewis Gaddis. It's informative. Covers a whole period of diplomacy with regard to Russia during the Stalin regime and the nuclear arms race. It's critical of Gaddis. Lears feels that Gaddis does not fully represent Kennan's regret about his position of how to contain Russia, which was characterized as "appeasement" by the Right Wing.
