The only way to destroy a hardened facility deep underground is from within and the Israeli’s have some ballsy operatives who can get high explosives into a secure facility.
You wonder if they didn’t have Saudi help in getting this done. Next to Israel the Saudi royal family has the most to lose if Iran goes nuclear.
The biggest threat to Israel comes not from Iran but from the Muslim terrorist in the White House.

The only scenario that I can imagine would be the Israelis threatening the family of an employee, forcing the employee to smuggle in explosives. But it’s hard to imagine an employee smugglling in a significant amount of explosives.
My alternative theory is a tunnel. But that’s probably too far out.
Just last week there was a news story about how the US has finally completed work on a giant earth-penetrating bomb, intended for just this type of application. So perhaps the US or Israel has dropped one of these on this factory.
