On this International Holocaust Remembrance Day, half the members of the Israeli Knesset have traveled to Poland,
with its old Jewish cemeteries,
and ghostly streets of Auschwitz.
There are concentration camp memorials where many light candles for a murdered six million.
Often young people will wear an Israel flag over their shoulders on this journey to the past,
the same blue and white flag that flies at the Israeli Knesset building.
Let us remember.
