That certainly sounds like the contemplation of an imminent attack to me.
Much of this alarm is centered on the International Atomic Energy Agency (IAEA) report last fall that suggested strongly that Iran was developing a weapons program. Iran has denied that, claiming any nuclear facility development was for peaceful purposes, like domestic energy requirements.
The IAEA has been strangely reticent in the wake of preliminary talks last week, to characterize Iran's defense, saying only that the talks were "good" and that more talks will take place next week.
A clearer picture, however, is given by the reactions of both French and Chinese diplomats have been urging Iran to better cooperate with the IAEA inspectors, who may already have a report in the pipeline that paints a not-flattering picture of Iran.
Today's events make it likely that Iranian policy will stiffen.
