Robert Menendez actually said...

I am deeply, deeply disappointed of their unwillingness to come in any session, public or classified, to have a discussion.

The entire inspection regime, the entire verification regime, depends upon the IAEA.

If you do not have economic sanctions to stop that Iran, then you really only have military force, or you concede.

My worst-case scenario is that, as you have described, a much stronger Iran, a much more economically resilient Iran.
