Last night I went to the official ceremony, held at Yad Vashem. Israel’s president, Reuven Rivlin, spoke about the need for Jews to free themselves of Holocaust trauma: “The Jewish people was not born in Auschwitz,” he said. “It was not fear that kept us going through two thousand years of exile, it was our spiritual assets, our shared creativity. . . . The Holocaust is permanently branded in our flesh. . . . Still, the Holocaust is not the lens through which we should examine our past and our future.”
