In July 2011, in an exclusive interview with the Associated Press in Washington, D.C., Jafarzadeh exposed for the first time the reorganization of Iran's nuclear program and the formation of a new organization run by the Defense Ministry, known by its Persian acronym, SPND, which oversees all nuclear weaponization work under the direct supervision of Iran's top nuclear scientist, Mohsen Fakhrizadeh Mahabadi. The information was compiled by the network inside Iran of Iran's opposition group, the MEK. This information provided by Jafarzadeh was later reflected in the November 2011 report of the International Atomic Energy Agency (IAEA).
