None of what she says will be news to many, but Einat Wilf does a rather nice tour d'horizon, I thought. In the end it's "power over time".
From the comments at Harry's Place :
Very good. My only niggle is that she failed to say that there had always been Jews in the region - both pre Zionist (say,1890s) Palestine and in the Arab world itself more widely. While small in numbers Jews never "left" either Middle East generally or the Levant specifically.
