Not sure what's the historical validity for that one source saying it was fraudulent, but this sure reads like anachronism. As someone that tries to defend him being part of selling ballistic missiles to Iran a very short time before it turning into a theocracy.

I am not completely inclined to believe Bergman because of me personally knowing one case where he published something completely wrong, and also this doesn't align with the cooperation Israel had with pre-revolution Iran.

In any case, it's theoretically possible, I guess
