I usually start at the beginning of the 20th century. Things were quiet under Ottoman rule. Sure, there had been murderers, thieves, land swindlers, corrupt officials, bigoted assholes, organized crime, etc., but for four centuries the society was as peaceful as we human beings can usually manage. The millet system the Ottomans employed made their empire very egalitarian. The problems associated with it, namely that it fostered separatism, had been addressed by the reforms of the 19th century. All subjects of the Empire were equal in status, and all were equally protected. And since Palestine had been peaceful for centuries up to that point, I think it's sensible to start with the question "what changed?", and to seek the answer to the question " what can we learn from that time to help people living in Palestine find peace again?".
Start wherever you like. But if you find that the things you are discussing appear to have come out of nothing and nowhere, you are probably ignoring something important about the initial conditions.
