BERLIN – “The idea is to learn from the first one [Holocaust] so the second one will not be able to exist,” Dan Tichon, chairman of the International Holocaust Task Force and a former speaker of the Knesset, told The Jerusalem Post on Wednesday, in a wide ranging interview about combating Holocaust denial and modern anti-Semitism.Tichon and former ambassador to Jordan Jacob Rosen, the coordinator of the Task Force (Israel holds its rotating chairmanship for 2010), are in Berlin for two and half days to prepare for a Task Force meeting in Jerusalem in October and a plenary meeting slated for Haifa in December to involve 350 people.
