There is a possiblity!
They can fly over Red Sea, Indian Ocean, Arabian Sea and then Iran is within their reach
They can also have midair refeuling over the international waters!
The only problem is not to be identified by any body on the way to Iran
Why shoot, Israel should make no secret, but rather start sending out these sorties randomly and fairly frequently, with the first ones stopping just short of Iran, till Iran gets the picture or else the bomb hits the bunker.
