For example, the precise details of how the International Atomic Energy Agency will inspect and monitor Iranian facilities is likely to be secret because the agency doesn't want to tip off other proliferators. The names of Iranian scientists associated with the program whom the agency would like to interview will also not be shared with the public.
This actually makes sense. We already know that Israel assassinates Iranian scientists suspected of involvement in the Iranian nuclear program, let's just give them the names of the ones that actually are. I can see why the P-5 +1 would wish to keep that secret. And disclosing the exact movements of the IAEA would be beneficial to any other countries that may wish to get around inspectors. Not to worry.
