What chance for the completion of the grand design -- Great Britain in the Common Market, the Commonwealth nations pacified, a partnership arrived at between the U.S.A. and this calarged Common Market. In a low-tariff trading area? After reading Mr. Lippman's articles this seems a major question mark. The deep rivalries within the Western World, with De Gaulle and Adenauer preferring to hold the trump cards, to sustain France's aspirations for independent nuclear strength so that the turn is not called by Washington: the danger- if this breaks up- of stronger lies between Germany and Russia: the age of the two European Leaders; the threat to a weakening of NATO. and internal difficulties Britain and the U.S.A. face over the plan add up to years of uncertainty. Mr. Lippman does not offer any solution. He simply charts the alluation, and for the average citizen helps clarify what seems able as a threat to peace.
