The Iranians seem pretty upset over no damage.
Discussion
The IAEA D.G has said that nobody is in a position to assess the underground damage at this time. Anybody saying it was destroyed, or anybody saying it wasn't is talking out of their ass cheeks. We will all wait and see.
Assuming that the government information is correct...
The visible damage in satellite photos is very minimal. Some subsidance is visible. Six bombs minimum with 15,000 lbs explosive each is a lot of energy. It had to go somewhere.
Logic says it went down and inside the facility.
Damage will be extensive.
How much is yet to be determined.
