All the Iranians have to do is say come on in and look around. Instead, they want to play chicken. Even some of their own leaders are getting tired of Ammadatjean for his theatrics.
The Iranians are already cooperating with the IAEA on the nuclear issue, and yet the Security Council is still divided when it comes to harsher sanctions, or any type of military strike in the near future. But, I will agree with your comment that the Iranian president's rhetoric isn't helping their case.
