An excerpt from, "Newly declassified documents reveal how U.S. agreed to Israel's nuclear program" by Amir Oren, Haaretz, August 30, 2014:
The Obama administration this week declassified papers, after 45 years of top-secret status, documenting contacts between Jerusalem and Washington over American agreement to the existence of an Israeli nuclear option. The Interagency Security Classification Appeals Panel (ISCAP), which is in charge of approving declassification, had for decades consistently refused to declassify these secrets of the Israeli nuclear program.
The Johnson and Nixon administrations concluded that, in talks with Rabin, it had been stated in a manner both “explicit and implicit” that “Israel wants nuclear weapons, for two reasons: First, to deter the Arabs from striking Israel; and second, if deterrence fails and Israel were about to be overrun, to destroy the Arabs in a nuclear Armageddon.”
