Hmmm...now, who would to kill an Iranian nuclear scientist? Beats *coughmossadcough* me.
This same sort of thing started to happen right before the 79 revolution except it was drive-by shootings mostly from motorcycles. The victims were normally government officials, police or US military people. We had a rash of these right before I was rotated back to the US. A couple of weeks before I left, an Army officer and his driver were killed in front of his house about six homes down the street from ours.
This is what I was waiting to see to signal the serious start of the new revolution. It would have happened sooner if the “man-child” would have at least given serious moral support to the protestors back in June.
