Moving Iran's Uranium Around

.

As I mentioned in a previous post, Iran brought their enriched uranium stockpile out of its deeply buried bunker so that it could be enriched further.

Why would they do that and expose what may be almost their entire inventory of enriched uranium to attack?

Well, I figured it out.  A massive amount of enriched uranium in a building on the surface is fairly immune from attack by the US or Israel because it would scatter to the four winds causing a radiological disaster.  So there was little risk.  Unless we came in and stole it.

Once they drew off enough to feed their centrifuges,  they moved it back underground, where it is completely safe.
