This account by Mr. Arthur Schlesinger, Junior, and Mr. Rovere of the Great Debate on American foreign policy, which was precipitated by General Douglas MacArthur's recall, is authoriative and, at the same time, highly readable. Both the authors are well-known commentators on public affairs, and Mr. Schlesinger is, as well, an historian of high repute. He has a Chair at Harvard, and his The Age of Jackson was deservedly acclaimed, being awarded a PPulitzer Prize. Their approach to their subject is that of Liberal, passionately concerned that free institutions should survive in the world, but realistically aware that their survival depends, in the last resort, on American power and how it is exercised.
