Iran is going to inspect to see whether Iran was building weapons?

"The agreement in question diverges from normal procedures by allowing Tehran to employ its own experts and equipment in the search for evidence of activities it has consistently denied - trying to develop nuclear weapons."

"That wording suggests that - beyond being barred from physically visiting the site - the agency won't get photo or video information from areas Iran says are off-limits because they have military significance."

I mean, it's still a great deal and all, but does this at all concern any of the deal's champions?
