Perhaps some of the targeted scientists were too educated and so not as stupid to follow a religion as much as their power mongers wanted? or were thought to be working too closely with the international atomic agency in negotiations for the benefit of Irans future, and not the zealots dreams of meglomania.
As to the other hinted at possible culprits, they do have a strong history of using any means they are able to get away with to achieve their assignments. In recent years a few of their cell groups have been thrown out of a countries, like Canada, Germany, Russia, UK etc for something.
Also after WW2, were they not the first modern terrorist/freedom fighters, killing many French, British locals to earn a claim, and have sometimes attacked and destroyed 'accidentaly' USN ships and aircraft.

It is that last point, that hypocritical dichotomy, that angers even some of their own supporters at times, not only the wider World who understand at least a bit of both sides of the argument - Some of it goes back to the wars between them and the Caananites too amongst all others who also moved into that area.

Sometimes I like the childishness of some topic themes and the humour of posters, other times, a few only bring themselves down to those others levels whom they critisise and seem almost racist or religous-ist towards.
