The history of the first Intifada shows that Arab demonstrations and rock throwing which caused few serious injuries, were met with Israel's reponse with 'rubber' a.k.a steel bullets and live fire which killed many. Your notion that Palestinian demonstrations might evolve into resumed bombing demonstrates the weakness of your argument, for you know very well that at the moment the Palestinian demonstrations are in the main non-violent. The truth is Israel does not want them to demonstrate at all, under any circumstances.
