That is like saying, "In June 1944, the US Army invaded France and killed thousands of people."
The statement is true, but it is totally lacking in context. The Arabs who fled did so because they were defeated in wars that THEY started. You neglect to mention that fact.
Sorry, your information is outdated. Please, do not rely on the IDF propoganda machine as a factual source.
" Finkelstein focuses on one aspect of Morris historical scholarship. While Morris reveals political and military leaders, he steadfastly - but according to Finkelstein falsely - maintains that the Arab exodus was not the result of a general, premeditated Yishuv (Jewish) policy (quoted on p.64 of Image and Reality). The Morris thesis is that the mass exodus of Arabs from their major population centers all over present-day Israel was not the result of a well-formulated plan to get rid of as many Arabs as possible, as quickly as possible. Rather, Morris maintains that Arab flight was a by-product of war. As in all wars things happen! Finkelstein shows that Morris obfuscation of the widely-known Plan Ds real objective is a falsification of the facts, plain and simple."
