Most books and people Ive spoken to ultimately go towards religion. Religion plays such a big part historically in the Arab-Israeli conflict, especially in regards to rights to holy places and bilblical rights to land,but how far does it go?
What are the other reasons that previous peace processes have failed? And is religion interlinked with these failures? For example having religion behind political decisions, creation of settlemebts etc..
Do politics, culture and education of the generations play a significant part in allowing the conflict to continue and the hostility between the Arabs and Israelis to remain
Ultimately, although cultural and political decisions and actions fuel and effect the crisis, would you say that religion is the main hindrance and is the biggest fueler of this seemingly continuous conflict?
Given that peace processes between the Palestinians and Israelis directly have focused mainly on going through the Arab-Israeli conflict, and only began in earnest between Palestinians and Israelis extremely close to the 20-year rule (1991 Madrid Conference with the joint Jordanian-Palestinian delegation, and 1993 Oslo Accords), it's hard to answer this question. Before then, Israeli-Palestinian peace had never been sought except by the attempts of the Arab states: Egypt, for example, attempted to include talks on how to deal with the Palestinian territories of Gaza and the West Bank during the Camp David talks, though it was ultimately unsuccessful in any resolution being arranged as the continuation of the conflict shows.
The other attempts come before Israel was established, of course, with attempts at partition and peace carried out by numerous actors, though primarily the British (obviously).
To discuss all of these would require at least a book's length response. Why each process failed is difficult to address, and depends a lot on who one asks: to respond to each viewpoint is difficult. And because it toes the 20-year rule line of the sub, and is so contentious and disputed even today, historical answers on the subject will be lacking. It was, of course, not until the late 1980s that Israel became willing to negotiate with the Palestine Liberation Organization (PLO) after their renunciation of violence and terror, and the harsh Israeli response to the mostly nonviolent (at first) First Intifada that began in late 1987 certainly didn't help negotiations start any sooner.
For more information, I'm afraid you'll have to ask somewhere that doesn't restrict the dates and allows more speculative answers, since history is not conclusive on this just yet.
