Former Mossad agent Victor Ostrovsky, in his 1990 book By Way of Deception, has accused the Mossad of knowing the specific time and location of the bombing, but only gave general information to the Americans of the attack, information which was worthless. According to Ostrovsky, then Mossad head Nahum Admoni decided against giving the specific details to the Americans on the grounds that the Mossad's responsibility was to protect Israel's interests, not Americans.
