I suspect what Israel is hoping for is that if they disrupt Iranian internal security enough, Iran wont be able to put down protestors. In the past there have been protests that Iran had to put down violently, so its not crazy. At the same time, hard to imagine anyone going out to protest while bombs are falling, and external threats tend to increase support for incumbants. So probably a long shot.
What they will probably settle for is blowing up their nuke stuff and missles, hoping that the economic disruption of the war is enough that its too expensive for iran to rebuild it.
Of course, nobody really knows.
