i think maybe you missed the news over the last few years from iran.
the people did rise up and disclaim the dictator, but they all went to jail or were executed. maybe you missed that? remember neva?
they even arrested rafhsanjani.
it is not as simple as you think, but if they would use anti personnel long range standoff glide bombs on the headquarters of the republican guard and the secret police along with kamani and akhmadinajad, then there would be the opportunity for a popular insurrection to overwhelm the regime forces.
instead of widespread bombing, it will be strategic. there supposedly is a cruise missile package which will fly along the high tension power lines dispensing chaff at each pylon of the line so that the lines will short out a little on each pylon leading to failure of the rebreakers at the hub. that will shut off the centrifuges and when they shut down then all the partitioned gases will diffuse backwards through the centrifuge chain.
i expect the saudis will conveniently ignore the israeli jets and i bet they will even allow them to land in saudi after their mission, then work out the details of repatriation afterwards.
