STEP‐BY‐STEP BID FOR MIDEAST PEACE SEEN LIKELY BY U.S.
June 1: US officials believe that likelihood of resumption of step-by-step approach toward peace settlement in Middle East is increasing; reporters aboard Air Force 1 carrying Pres Ford and Sec Kissinger from Brussels to Madrid are told that Ford's meeting with Egyptian Pres Sadat in Salzburg will be 'very important, crucial meeting'; are told that unless there is some progress toward peace 'it is mathematically certain' that war will break out in 6 mos to 2 yrs; US officials believe there has been resurgence of interest in step-by-step efforts toward peace and that USSR, which has been strongest proponent of Geneva peace conf, has become aware of complexities of full-scale Geneva meeting and consequences of failure; do not expect any 'spectacular' announcements after Sadat-Ford meeting because developments at Salzburg will have to be presented to Israeli Premier Yitzhak Rabin on June 11 and 12 before they become public (M)
