Trace Gallager: All this comes amid a tense nuclear standoff between Iran and Western leaders. Terrorism expert Steve Emerson joins us now. He is executive director of the Investigative Project on Terrorism which is a non-profit research group focusing on radical Islamic and extremist groups. The fascinating thing to me about this whole thing Steve is that this bug was actually able to go in and kind of disable many of Iran’s centrifuges – those are the things that spin uranium to make it pure. And at the same time it was able to monitor the damage it was causing to those centrifuges.
Emerson: This was the most amazing and unprecedented virus ever conceived of precisely for what you said. One, it infected the system and it actually destroyed– the code actually made it more destructive as it spread throughout the system. Plus it gave the ability for the Israelis and the Americans to monitor the damage and also to actually remotely control how it spread throughout the system. It was a devastating virus and it has still infected part of the Natanz plant which is why Iran had to build redundant facilities to build centrifuges that had been corrupted by the Stuxnet virus.
