Believe me,” President Sadat understated recently, “we are in an era of wonders.” Despite all the hopeful allusions to pensive deserts, moody mirages, monumental pyramids, and lifesustaining rivers, it is still hard to express the sheer audacity of President Sadat's pilgrimage to Jerusalem— not primarily a pilgrimage to Al Aksa for Greater Bairam, but one to the Knesset for peace. We will not likely in our lifetime see again an event so Tolstoian; a single man, a single act of will, and a history that, with the unlikely exception of an assassination followed by a complete and immediate reversal, can never be quite the same again.
