This is CBSI on the world. I'm John Batchel. It's a pleasure to welcome someone I've depended

upon for years about the suspect Iranian nuclear weapons program, David Albright, the president

and founder, chief executive of the Institute for Science and International Security.

David, a very good evening to you.

The question of bomb damage, I am understanding that it takes some time.

It's a bit of an art form to do it from the air, which is what we've seen so far.

Nonetheless, there are things to say about the sites that have been struck by the Israeli

Air Force and then the U.S. Air Force.

We begin with Fordo, the mountain, the nuclear mountain.

There are images that are reproduced routinely everywhere of holes in the mountain,

three holes bunched and three holes bunched.

What are we looking at, David, and what can we measure about what's down underneath?

Good evening to you, David.

Good evening to you.

The poles are from these massive ordinance penetrators, and it looks like 12 were used in total, in a sense,

And what we've found from satellite imagery and our information about Fordow is that

they found two vulnerabilities in the mountain, one of which is a ventilation shaft that's absolutely

critical to the operation of the enrichment plant that goes from the surface all the way down

to the facility. And three of them, three holes are right aligned with the ventilation shaft.

There was the other three holes are aligned with some kind of structure that was on the surface.

And we don't really know what that is, but it looks to be a vulnerability.
