An attack on Iran's nuclear facilities with a risk of Chernobyl. Not how much Splenda to order next month.
That's a pretty big assumption; if a nuclear event were considered a viable risk, then the levels of oversight within our existing government would be in play. However, if the President had already stated his desired end state accepted as risk a possible catastrophic event, then there would be no need for him to make that call as it was already inherent to his original decision. In this case, a nuclear event was not even a potential result. This was harassment, designed to delay. If a Chernobyl event was an acceptable risk, then cyber was the wrong tool for the job, and believe it or not, we have some pretty smart tool users in the DOD.
Do you suppose the entire US military complex is usually idling in park awaiting the next objective to spring forth?
