I left another comment to you elsewhere about this, but no this conflict is not ancient. Israel likes to claim it is as justification of their actions, but Arab Jews and Arab Muslims lived together reasonably peacefully in this area for centuries. The current conflict was created by the European Jews immigrating, buying land, and refusing to hire anyone except Jews for jobs the Muslims typically held. It removed any hope of creating a livelihood from these people and giving them resistance as the only option left available. This is where the violence starts. It's only about 100 years or so.
