sooner or later. Iran now suspended cooperation with IAEA. 1. The bill is passed by parliament. But it has to be approved by Iran Guardian Council to become law. Don't forget Iran parliament also passed the bill to shut down strait of Hormuz. But the stait still is opening now. 2. Suspension of cooperation with IAEA is temporary, not permanent. Again, sooner or later Iran has to accept inspection from IAEA if they remain the member of NPT.
Fordow nuclear site is buried in mountain and is hardest one among 3 nuclear sites to damage. But satellite image shows the hole hit by GBU-57 is right above the main lobby of underground at Fordow. Also from satellite 2 entrances' area were hit by GBU-57. So, the bombing is accurate. As for its damage, just like bombing a building, you don't have to completely destroy it. If your bombing has impact on its structure caused a safety hazard and its repair is not cost effective, this building then can not be used. So, from practical perspective there is no difference between a damaged building that can not be used anymore and the building that is completely destroyed.
