First, I didn't post the post about debunking the AP article. The above is really long. However, it gives you the history of conflict between Iran and IAEA.
Apply a little common sense, if possible. Given the history between the two why would the IAEA give Iran anything that it wants, especially after the P5plus1 agreement with Iran. The IAEA is now going to look the other way, so Iran can cheat on the agreement that took close to two years to agree upon. How does that make any sense?
