The Jewish Naqba and how its story is suppressed

There is a great article by Michelle Huberman "Where are the Ashkenazim?" that describes how the Ashkenazi liberal elite in Israel have continually downplayed the catastrophe that befell the Jews living in Arab lands after 1948. While the whole world has been brainwashed into accepting the narrative of the Palestinain 'naqba' - where about 600,000 Arabs fled Israel at the request of the invading Arab armies - few people are aware of the far greater number of Jews who were forcibly expelled from their homes in Arab countries.  
The article struck a special chord with me because this subject came up last September in a talk by Dr Noam Leshem who is the archetypal Israeli liberal that Michelle refers to. Leshem, who is apparently employed by BICOM to 'promote Israel' and also 'advises senior Israeli politicians',  actually presents only the standard Palestinian anti-Zionist narrative. A member of the audience asked him specifically about why the Israeli government did not make more political capital from the Jewish naqba. His response was abrupt and rude. He said something like 'that is a dead subject - there is absolutely nothing to be gained from raising it'. The problem for people like him, of course, is that it does not fit in with his narrative, so in the traditional leftist way he simply refuses to acknowledge it.
