I will tell you where I get the impression that their was attempted ethnic cleansing. When I say ethnic cleansing, I accept the same definition used by Ilan Pappe, barrowed from Drazen Petrovic, in "The Ethnic Cleansing of Palestine". "... a well-defined policy of a particular group of persons to systematically eliminate another group from a given territory on the basis of religious, ethnic, or national origin." (2006, p.1) In Benny Morris' "1948 and After: Israel and the Palestinians" , a report is referenced from the IDF intelligence service that discusses the primary reasons for the Palestinian exodus. The first three listed have to do with operations by the Haganah and other paramilitary groups. Falling at number 4 is decrees of Arab leaders to flee. (2003, p.88-9) The following 2 have to do with psychological warfare and "expulsion orders".
