Since I've read his book, The Birth Of the Palestinian Refugee Problem this is no surprise. While typically categorized as a "New Historian", Morris, when he kept with the historical record was pretty good and indeed reflected exactly the blame he is indicating in this article, i.e, on the Arabs. It's when he started fooling around with the primary sources where the problems arose as Efraim Karsh pointedly showed in his book Fabricating Israeli History(2000).
