An informative, realistic account of British policies, beginning with postwar illusions and post-Suez depression to the present, somewhat grating mood of Mrs. Thatcher's "We now have a new Britain, confident, optimistic, sure of its economic strength. . . ." The authors, both with earlier Conservative positions and now with major responsibilities at Chatham House, emphasize the economic aspect of foreign policy, and point to the need for greater political openness in regard to the realities of foreign policy-in which traditional sovereignty plays ever less of a role. Not by stealth can the necessary domestic consensus be created.
