No they won't..
Israel long realised most Arabs arent as unified as everyone thinks, same as with Hispanics..
This ain’t about unification.
I worked with a dude who was an Arab translator in Afghanistan.
I told me the majority of the terrorist they caught were just dudes from other ME countries who were just paid to kill American soldiers by elites in other ME countries.
Dudes didn’t care one way or the other about the future of Afghanistan. Just money to send to their families.
Israel obviously got a hell of an intelligence apparatus but a bunch of random unorganized attacks may outwit even them.
