Israel won’t have a choice to not attack because Iran has already declared numerous times that they will destroy Israel. The choice is either to wait it out and hope for an open miracle when Iran does use the bomb that they will create or the other choice is to prevent them from getting the bomb (which would also be miraculous tbh).
Iran is no more and no less commited to destroying isran based on this deal. Their goal to destroy Israel is totally unrelated to the outcome of the deal. However, because of the deal, they will now have the means to create a bomb. They are not more interested in destroying Israel because of this deal, however, before they financially and realistically could not do so. Now, however they can.
