Western intelligence has known it for years"
The military blogosphere -if blogs picked the story up at all - was not pleased. So far the only reactions I found considered the "news" to be horrible (if true).
Now think again. What would it mean if Iran has had operational nukes for years?
It would mean that they didn't even bother to use them for the purpose of deterrence, much less actually use them or even give them to terrorists: All the horror scenarios about Iran's behaviour as nuclear power would have been obliterated by recent history.
Yet, many people are so much conditioned to think that everything about Iran is bad that they don't really seem to think any more.
