Iran’s nuclear program has been setback by a computer virus for at least 3 years not that long ago by Isreal.
Islam is not even interested in high yield nukes. They just want fissile material. Dirty bombs would be fine. Nobody can broadcast news footage of a yigh yield nuclear ordinance blast @ 10,000 feet AGL. The landscape becomes something else. They want thousands of half walking dead victims puking their internal organs out to show the glory of Allah against his enemies, and the film crews to shoot it.
Unfortunately, that didn't deliver much "Shock and Awe" to the rest of the neighborhood.
