Hehe. The saddest part of such a war would be the siege of Austin. But I'd pay to watch it.
I have a lot to learn about the historic tensions in the region. But unyielding religious fanaticism seems to be the universal mechanism of unrest. As for the reasons, take your pick. I couldn't care less about Israel - at least, not any less than I cared about all the other existential genocides we've watched from a distance. If Dune was a parable for the middle East, we await only the rise of Muad Dib to create a "united Arakis" (pan-Arab state,) take control of the "spice" (oil) that makes "space travel" (modern industry) possible, and conquer much of the "stars" (who knows, but nuclear war would be involved.)
If you think a nuclear Arabia would be satisfied with holocausting just Israel, I'd love to buy you a beer and hear your story! For myself, in my ignorance, I'm kind of OK with disunity in the region.
