I was disturbed by the implication that the researchers should stop investigating Stuxnet (or refrain from publishing) because of the possibility that it was a US or Israel covert op. There are so many problems with that reasoning, and I'm glad they weren't swayed by it.
Furthermore, even if Iran does make WMDs, they do not pose a serious threat to Israel or the United States. Their delivery systems (missiles/rockets) are very antiquated and can be reliably intercepted and a suitcase nuke has extraordinary low yield. And even if they somehow gain the capability to effectively use their WMDs they would not do so due to MAD.
You cannot say the same of True Religious Believers.
This is incredibly naive. A simple ship sailing into NY harbor could easily deliver a nuclear weapon, even if it was large and unrefined. This is especially the case for a U235 gun-type (ie Little Boy) weapon, which requires relatively little sophistication.
And even if they somehow gain the capability to effectively use their WMDs they would not do so due to MAD.
Nobody would fly airplanes into a buildings because human beings want to live, right?
