The problem is AIEA wants to go to the sites which are not in its jurisdiction, this is unacceptable!, given that iran has not yet signed the additional protocols which would render those sites accessible to aiea. So AIEA should play by its rule, not outside the rules.
In this move, i understand the iranians very well and they are right not to let them do so!, a country should not open its military barracks for inspection just to please the zionists.
Remember, it is AIEA which gave the iranian scientists names to the zionists and lead to them being killed in a cold blood by mossad, what do you think gonna happen to iran if it let these AIEA (spy agents) go inspect its military hardware?
