It is a book that cares about liberty, choice and a moral compass, that warns against hubris' Roger Boyes, The Times John Lewis Gaddis, the distinguished historian and acclaimed author of The Cold War, has for almost two decades co-taught the grand strategy seminar at Yale University with his colleagues Charles Hill and Paul Kennedy.
