I have now read the latest International Atomic Energy Agency (IAEA) report on Iran. It is clear that the IAEA is being pressured to toughen their stance.
The tough language is almost completely rhetorical. They still clearly assert that "the Agency continues to verify the non-diversion of declared nuclear material in Iran," which is the bottom line. Aside from this there is barely anything new in the report.

To the extent that Iran is condemned for its nuclear activities, it is on the basis of broad and unsubstantiated speculation ("concerned about the possible existence in Iran of past or current undisclosed nuclear related activities") and on the current assertion that the Additional Protocols and the Code 3.1 modifications are binding on Iran. This is an evolving situation. In previous IAEA Reports, Iran was asked to implement these additional protocols, or a hope was expressed that they might do so. Merely declaring them to be binding does not make them so--as those disappointed with the fate of the Kyoto accords in the United States will attest.

One wonders how much the United States contributed to this report, because the technical aspects are cut and dried. The final sections have all the dark speculation -- speculation that mirrors what we hear from the U.S. administration.
