We will see in the next few days what demolition of Gaza actually means. By killiing and kidnapping Israeli civilians, Hamas has lost Palestinians all international sympathy. There will be no constraints on IDF as it extracts revenge on the hapless Palestinians.
The whole operation was a cynical ploy to derail the Saudi- Israeli rapprochement. I am sure MBS is extremely pissed, but I doubt Saudi Arabia will go out of its way to restrain Israel. Delaying the Saudi- Israeli helps just Iran and keeps neutral countries like Jordan, Egypt, Qatar, Turkey, China and India relevant in the mediation process a little longer, but apart from that everyone loses- most of all ordinary Palestinians.
