A sensational story is rocking Israel this week – alleging that the Israeli military defied orders from its commander in chief, Prime Minister Benjamin Netanyahu.

Leading Israeli journalist Ilana Dayan is reporting that Netanyahu ordered his military to prepare for an attack on Iran's nuclear facilities nearly two years ago. Dayan's story documents that both the army chief and the head of Mossad (Israeli intelligence) refused to comply with Netanyahu’s order.

In an interview with CNN’s Christiane Amanpour Thursday, Dayan said the information came from officials who were in the room with Netanyahu when the conversations took place, during a meeting of Israeli ministers.

“It happened in the course of 2010 and all of a sudden, just when they are at the door, the chief of staff [of the Israel Defense Forces], then Gabi Ashkenazi, and the head of Mossad, Meir Dagan, are given an order by the Prime Minister Netanyahu to step into a pre-attack alert and be ready to strike in Iran.”

Dayan told Amanpour that she believes this is the closest Israel has ever come to striking Iran, but the dramatic rift between the military and political establishments stopped it.
