There will never be peace in the ME until the King of Kings returns to reclaim what is rightfully His, and that is all of Creation redeemed through the blood of His Son. This feud, and that's exactly what it is, stems all the way from Abraham's sons Isaac, who is his proper firstborn through his wife, Sarah, and Ishmael, the bastard son conceived through Hagar, Sarah's handmaid. This is the real reason why Arabs will never be at peace with Jews (and to some extent, Christians either) as G-d's blessing was extended ONLY to the descendants of Isaac.
