Changing Direction is essential reading for anyone interested in the emerging Cold War and the new edition contains remarkable new material from the latest declassified files. It reveals the furious arguments of Whitehall warriors on the brink of a dangerous new community - everything is here." Professor Richard Aldrich, University of Nottingham

"When this book was originally written as an Oxford D.Phil., in the early 1980s, its heavy typescript was regarded as worth its weight in five-pound bills to eager historians of the origins of the Cold War: the lucky ones were tipped off by their supervisors about its existence, and the word about it was spread most confidentially...The second editon was occasioned by the release of more documentary material in the Public Records Office in Kew...Dr. Julian Lewis has drawn upon these to fill in blanks in his earlier careful reconstruction of the discussions and arguments which led British defence planners to develop contingency plans for the event that the United Kingdom's Ally, the Soviet Union, should begin to pose a threat to Britain." - RUSI Journal'an invaluable source for recent British history' - Contemporary Review'Lewis is a meticulous historian who writes clearly and persuasively, and with great authority.
