Mind you... I'd agree with many in this thread that Israel would surely be struggling to attack Iran's "nuclear facilities". Apart from anything else, there are a LOT of "nuclear facilities" to attack !
On the other hand, I wouldn't rule out them pulling off some sort of "Entebbe on Steroids" commando-raid-type mission. After all, a nuclear facility under a mountain blows up just FINE if you plant the bombs INSIDE it.
With this bomb, all they have to do is drop it. It will penetrate 200 feet of 5,000 psi concrete before exploding. MOP.
