Okay. Then explain why the attacks against Jews in the Levant have been taking place since way before the '48 war?  Please explain Mohammed Amin al-Husseini? 

As was the case in the Second World War and any conflict in general, an extreme action results in an equally extreme reaction. Unlike the Palestinians, at no time did the French Resistance or Tito's partisans not accept responsibility for their actions. The French Resistance took no prisoners, the Germans executed French Resistance members or sent them to Natzweiler. Tito's partisans committed mass murder, so did the Germans. If any murder of Israelis is justified in your mind, why isn't Israeli retaliation?
