A school history textbook needs to record the facts about what happened and not "claims" or "contentions" by war propagandists. Anyone who says that there is an Arab and an Israeli "version" of the war of independence is a liar. There is only one version of the facts about what happened although there may be different interpretations of those facts. It is not normal, though, to teach interpretations at this level of the education system. Before they are ready to study interpretations the students need to know the basic facts so that when they study interpretations later they can understand them. This textbook seems to have been a politically motivated exercise in trying to forcefeed the children Palestinian propaganda before they have the knowledge to recognise it. That is not education, that is brainwashing.
