Just a few of the many points which come to mind. 1. Nearly all Arab states threatened to launch a war against Israel before the state was even formed, if it did form. This was from the time of the UN partition decision in 1947. 2. While Arab and Jewish fighting broke out at the local level before the Arab armies arrived, this was provoked by the coming battle they had promised. 3. As to whether more Arabs left under pressure to do so, or left despite Jewish calls for them to stay (each happened in different areas) is debatable. I note Arabs often cite the willingness of Jews to recognise both occured, but only cite them for evidence of admission that Arabs were forced out. 4 the state of Israel won territory in the 73 war also (they gave the Sinai back to Egypt with peace - something Lebanon and Syria should remember).
