1) Hamas jihadists cultivate decades of repression of the Palestinian populace into a spectacular terrorist strike on Oct 7th.
2) Israel, an apartheid ethnostate, where Rabbis call for extermination of Palestinians in response to the Hamas strike (after decades of dehumanization), drops a nuclear payload worth of bombs on Gaza - which kills thousands of Palestinians (but only a few dozen Hamas soldiers).
3) In the US, Christianist pastors and churches back the Israeli government's push to ethnically cleanse Gaza - primarily because apocalyptic prophesy requires Jews to be in the "holy land" - all of whom are prophesied to perish.
In all of these cases, all of the involved religions make the conflict unavoidable. There were steps to peace in previous decades but religious extremists assassinated key figures to prevent peace.
This isn't exclusive to this region or these religions, of course.
