‘Apparently not the thin red line. I don’t think anyone is going to attack Iran. Many of their facilities are 70 feet underground, and moving around concrete will not do the job.’

Actually, given the centrifuges used, a well placed piece of very heavy ordinance could in fact seriously disrupt the program. You require thousands of these things spinning at very high rpms, so high that ‘negotiating’ several speeds is a tedious, dangerous process all by itself. A ‘good shake’ from a weapon dropped perfectly, or even a act of nature like a earthquake could wipe them all out just because of the physics involved, from what I’ve read.

I thought Iran had spread around their facilities all over the country. I know we have bunker busters, but given how many of Saddam’s bunkers survived, I wonder how many days of bombing would it take.
I suppose the USA could get the job done, if persistent. However, Israel using conventional weapons probably doesn’t have the ability to destroy all the nuke facilities.
