Scientists associated with Iran’s nuclear program are being killed at a good clip. Most suspect that Israel is behind their deaths. While publicly such acts are denied it does seem to be with not only a wink but with the tacit approval, if not covert assistance, of other states in the region.
Mostafa Ahmadi Roshan: Mostafa Roshan was a supervisor at a department at the Natanz uranium enrichment facility in Isfahan Province. He was killed after a motorcyclist attached a magnetic bomb to his car on 1/11/12.
Darioush Rezaeinejed: Nuclear scientist killed 7/23/11.
General Hassan Tehrani Moghaddam: On 11/12/11 seventeen members of the Revolutionary Guard, including Moghaddam, were killed in an explosion at Moddares missile depot that also destroyed 180 Shahab 3 missiles.
The methods may make us deeply troubled. A nuclear Iran should make us more-so.
