Today is Yom Hashoah, Holocaust Remembrance Day. On Israeli t.v., Schindler’s List is playing. The other channels have been showing discussion shows and reflections on the Holocaust all night.

Making the day more resonant are the ravings of Iran’s president, Mahmoud Ahmadinejad, who calls for the destruction of the Jewish refuge even as Iran races to develop nuclear weapons.
