DEBKAfile's intelligence sources report that the Stuxnet malworm which played havoc with Iran's nuclear program for eleven months was not purged after all. Tehran never did overcome the disruptions caused by Stuxnet or restore its centrifuges to smooth and normal operation as was claimed. Indeed, Iran finally resorted to the only sure-fire cure, scrapping all the tainted machines and replacing them with new ones.
Iran provided confirmation of this Tuesday, July 19 in an announcement that improved and faster centrifuge models were being installed.
