a thought.
the US and Israeli authorities have no intention of bombing the Fordow site. doing so would possibly release radioactive material which would contaminate the surroundings possibly for many years. and moreover, the victors will want to have convenient access to inspect the site and clear out all sensitive material and enrichment technology, and solidly account for what's there and ensure that no one (official Iranian regime or otherwise) has absconded with equipment or materials. the site would be much more difficult to safely inspect and contain if it had been smashed with a 5000lb bomb than if not.
what they want rather is for the site to be surrendered without a fight.
all the talk of bombing Fordow is bluster and distraction until either Iran surrenders or US+Israel kill Khamenei.
failing either of those, Israel would assault the site. but that's messy (for the same reasons bombing with the GBU-57 would be) and could cost Good Guy lives.
