This bombing was for show. The US did not use the required munitions to destroy these targets. Not even close.

12 of those bunker busters in succession? High chance the facilities really were destroyed.

They dropped 12 of the GBU-57s. What would you recommend?

There are limited ways to destroy Fordow. US is only country to possess them

They do have reactors though, do they not? Hitting the spent fuel pools and/or the reactors would produce detectable radioactive contamination. The HEU? Not so much as its half-life is 700 million years, and the stuff is dense and will quickly settle down.

Why would they have reactors? This is uranium enrichment, not plutonium production.

Why would they not have reactors? Plutonium bombs are more efficient than uranium bombs, so of course they should want to make some plutonium. Remember, they claim they need HEU for civilian reactors.

Plutonium bombs are massively more complex than a U-235 design.

For sure, but a) they have a civilian reactor program, which surely produces spent fuel, and if they run it with HEU then they probably have breeders, and they might think they can figure out how to make Pu bombs. After all, the W88 bomb design got leaked in the 90s, remember?
