Striking nuclear program components of critical nature for the bomb program could not be done with distance weapons alone, would need fighterbombers inside Iranian airspace, most likely, also would need warheads of a size that make them practically equivalents to small nukes. The two key facilities of Iran are practically buried under mountains that would be needed to be practically blown up. One can safely assume the Iranians know this and did not leave it as open as Tora Bora. I am not certain it can be done without troops on the ground in these locations, and no matter the chosen tactical method it woud, be a very extremely high risk operation. As long as one does not want just to push a symbolic action. In which case one must ask the question - why then taking any risk at all? Iran turned itself into a joke with its 320 missile/drone attack, militarily it was a desaster for them - this time.

Very difficult choices. No matter the plan, if it goes wrong, it costs Israel the nimbus of being militarily very capable. And that, albeit being an immaterial one, would be a loss hard to overestimate. If you lose the nimbus of being a fearsome enemy, then your enemy will not fear you anymore. Not good.

This is like a chess position where all moves available cannot improve or even just support the current situation, but can only compromise it - but making a move you nevertheless must, skipping a move is not allowed.
