We know that the source, DEBKAfile,  is not always completely reliable, but this report seems to us to ring true:

President Mahmoud Ahmadinejad’s personal cameraman, Hassan Golkhanban, who defected from his UN entourage in New York on Oct. 1, brought with him an intelligence treasure trove of up-to-date photographs and videos of top Iranian leaders visiting their most sensitive and secret nuclear and missile sites.

The cameraman, who is in his 40s, is staying at an undisclosed address, presumably a CIA safe house under close guard.

He stayed behind when Ahmadinejad, after his UN speech, departed New York with his 140-strong entourage. For some years, Golkhanban worked not just as a news cameraman but personally recorded visits by the Iranian president and supreme leader Ayatollah Ali Khamenei of top-secret nuclear facilities and Revolutionary Guards installations.

When he left Tehran in the president’s party, his luggage was not searched and so he was able to bring out two suitcases packed with precious film and deliver it safely into waiting hands in New York.

The Iranian cameraman has given US intelligence the most complete and updated footage it has ever obtained of the interiors of Iran’s top secret military facilities and various nuclear installations, including some never revealed to nuclear watchdog inspectors. Among them are exclusive interior shots of the Natanz nuclear complex, the Fordo underground enrichment plant, the Parchin military complex and the small Amir-Abad research reactor in Tehran.

Some of the film depicts Revolutionary Guards and military industry chiefs explaining in detail to the president or supreme leader the working of secret equipment on view. Golkhanban recorded their voices. …

Although Golkhanban’s defection to the United States and request for asylum was disclosed to the media some days ago, Tehran has not made any comment.

The report may be telling the truth, but is the defector? It is more than possible, even very likely, that an asylum-seeker bearing valuable information is on a mission to deceive. As the report says:

From his years as a member of the loyal Bassij militia, the cameraman earned the complete trust of Iran’s security services and was able to reach his professional pinnacle as personal photographer for the two most eminent figures in the country, Khamenei and Ahmadinejad, with the task of recording their most confidential pursuits.

Were they fooled? Or is the US being fooled?

If the information is genuine, will it prompt an attack on those nuclear installations? Not, we think, while Obama is (absurdly!) Commander-in-Chief.
