high tech bunker busters that were only developed since the conflicts in Afghanistan...deep penetrators.
Without those the deep underground nuke facilities can only be marginally damaged. Even with those the nuke facilities can only be set back greatly, not totally destroyed.
Shouldn't the damn CIA know EXACTLY how deep those bunkers are? What are we paying them for?
Second point: Don't you suppose Iran has an engineer or mathematician who can calculate the depth at which bunker busters become inefficient, and then build the bunkers deeper than that?
