If this is Mossad, then they seem to have found a way to delay Iran's weapons programe without Iran retaliating. The issue is: Is this enough? Will this stop Iran or just anger them? If Mossad know these attacks are just pin pricks, what is their real goal? Perhaps they want Iran to strike Israel, so that American can get involved, and crush Iran, so these attacks are just provocations to make the regime do something foolish.
