As reported yesterday by Iran's Fars News in an article entitled "DM: Iran Not to Allow IAEA to Inspect Every Site":
"Iranian Defense Minister Brigadier General Hossein Dehqan warned on Wednesday that Tehran would not allow the International Atomic Energy Agency (IAEA) to visit every site and facility that it wishes.
'Iran does not plan to issue permission for the IAEA to inspect every site,' Dehqan said in an interview with al-Mayadeen news network on Wednesday.
. . . .
The Iranian Defense Minister reiterated that the time had come for the Americans to realize that they were not the world's super power and no one recognizes them as such any longer."
Or stated otherwise, the IAEA can inspect where Iran is not advancing its nuclear weapons development program, but not where the program is being implemented.
Yup, Obama's nuclear deal with Iran isn't worth the paper it's printed on.
