Lots of questions, so let's get to them. But first I want to mention that some readers last week took me to task for poking fun at Herman Cain's concerns about the mountains in Iran possibly thwarting an attack on its nuclear facilities. Perhaps I was a bit too quick off the mark (that's the problem with a chat format.)
One reader send along an interesting report by the Institute for Science and International Security, which noted:
"Commercial satellite imagery ... indicates that Iran is building a tunnel facility inside a mountain about two kilometers south of the Natanz uranium enrichment complex. The construction activity is taking place in the closest mountainous area to the Natanz site, strongly suggesting that the site is affiliated with Natanz.
***
"Iran earlier built a tunnel complex near the Esfahan Uranium Conversion Facility to protect a range of nuclear-related equipment and materials and natural uranium hexafluoride from that facility. Iran may be constructing a similar facility near Natanz, fearing that the underground halls at Natanz are vulnerable to destruction by military attack. Such a tunnel facility inside a mountain would offer excellent protection from an aerial attack. This new facility would be ideal for safely storing nuclear items, including centrifuge manufacturing and assembly equipment, centrifuge components, natural uranium, and low enriched uranium."
So while Cain could have phrased his answer better, he may have had a point. So I withdraw my earlier comment. Thanks to the readers who questioned me about this statement.
