I find this argument hard to believe. Israel had complete air superiority for a week and was monitoring all the sites, routinely hitting the above ground nuclear facilities. I’m skeptical Iran could transfer anything significant from Fordow and not be immediately spotted by Israel.

I still consider the main report to not be substantiated. Israel claims that they know where the stockpile is and that they have been monitoring sites[1][2]. Some official even claimed it’s mostly under the rubble. Not sure why one is to believed and the other not when neither have hard evidence.
Israel could not spot hundreds of Hamas terrorists rehearsing the 7 of October attacks, and using cell phones for weeks, 20 miles from their Urim base in the Negev desert. [1]
