With regard to massacres perpetrated by the IDF at the end of the war and particularly during Operation Hiram, where around 10 massacres occurred, Morris and Yoav Gelber consider that lack of discipline cannot explain the events. Gelber points out the "hard feelings the soldiers towards the Palestinians" and the fact that the Palestinians had not fled like in former operations. Benny Morris thinks that they were related to a "general vengefulness and a desire by local commanders to precipitate a civilian exodus".
