Simplicius should be reading our own @MarmiteLover123@hexbear.net, as a lot of those assertions are just plain wrong. For example, they have way more of those bunker busters and manufacture 6-8/month. The 20 refers to a specific model number of them, presumably the one with the George H. W. Bush memorial tailfin.
I agree that clearly Israel/the US didn't deliver a knockout blow to Iran's nuclear program, but they did hit a lot of anti air, suppressed missile launchers, and more critically, they demonstrated willingness and ability to indiscriminately bomb civilian infrastructure. Missile launchers can hide, apartment blocks and universities can't.
fair, I should have said willingness and ability (i.e. stealth/SEAD/DEAD)
