Defense Minister Moshe Dayan [told] the prime minister that “this is the end of the third temple,” referring to an impending collapse of the state of Israel. “Temple” was also the code word for nuclear weapons. Prime Minister Golda Meir...made the decision on the night of 8 October. The Israelis assembled 13 twenty-kiloton atomic bombs. The number and in fact the entire story was later leaked by the Israelis as a great psychological warfare tool. Although most probably plutonium devices, one source reports they were enriched uranium bombs. The Jericho missiles at Hirbat Zachariah and the nuclear strike F-4s at Tel Nof were armed and prepared for action against Syrian and Egyptian targets. They also targeted Damascus with nuclear capable long-range artillery although it is not certain they had nuclear artillery shells.
