First published in 1981. The Council of the London Institute of World Affairs has carefully reconsidered the lessons to be drawn from the Institute's record in its first half-century and reshaped its plans of activities for the 1980s. As in an earlier "cold peace" era, the Council is united in its resolve not to be taken by surprise by any of the contingencies that, on a darkening world scene, must be anticipated in medium-range planning.
