Maybe the Israelis are taking their program down one scientist at a time.
That was one of my first thoughts, but as has been further revealed, *this* particular scientist was not part of the Iranian Nuke program, but a teacher at a college and a public supporter of the opposition movement. It makes much more sense that this was a killing sanctioned by the Iranian hardliners and carried out by the Iranian secret police, who wanted to make it look like it was carried out by the “enemy”. Two birds as it were. Making for further justification for their brutal crackdown.
Besides *they* are the ones who have the explosives and who’s Hizballah forces, Quods fgforces, and imported Lebanese thugs sent by Nasrallah, to beat the Iranian people, are the ones who are trtained in such murder attacks.
If you bomb physical facilities they will rebuild them.
If you kill key personnel they wait until more graduate from university...
