1) I don't believe that Israels enemies are able to create a lasting alliance before and during a prolonged war against Israel. Egypt and Syria did something like this before 1973, but even that failed. Egypts demands on when the war should start deprived syrians of seven hours of daylight in Golan. And then syrians demands on Egypt forced them to leave the SAM umbrella at Suez, getting shred by the IAF. Why should an alliance with more parcipiants, more goals and far more losses work any better? Sooner or later some countries will withdraw - either openly or de facto, refusing to advance/defend.
2) Since the war is ignored by the rest of the world Israel could take its time. No running against a UN deadline (like 1956, 1967 or 1973). And they get to keep any arab army they bag. Which arab country would keep fighting after seeing the equivalent of Egypts Third Army being marched off to POW camps?
3) Israel could blockade Egypts, Syria, Lebanons and Jordans ports. Just declare the off-limits to everyone. Do the same to the Suez channel, just to deprive Egypt of cash. That should be a hard blow in the long run.
