Not only do very specific arming circumstances need to happen for a nuclear weapon to detonate as designed, but they are typically in very hardened locations. And beyond THAT the weapons themselves are small and hardened enough that even a very close strike would just throw it around, at the worst, direct damage to the weapon might cause localized radiation effects at worst. You're just not going to vaporize the core of a nuclear bomb.
It doesn't help that Israeli nuclear weapons are entirely unofficial and don't technically exist, so lord knows you'd need better intel on locating them than a nation riddled with Mossad agents at the highest levels can muster. You also need a weapons platform capable of hyper-precise targeting, which we already know the Iranians don't remotely have, plus bunker-busting warhead capabilities.
So not an option, not a possibility, and that's for the best for everyone.
