“Mike [Hayden]’s report clarified my decision,” Bush wrote, adding that he called then-Israeli Prime Minister Ehud Olmert, who wanted the United States to destroy the reactor. Bush says he told Olmert, “I cannot justify an attack on a sovereign nation unless my intelligence agencies stand up and say it’s a weapons program.”

Bush didn’t reveal, however, that his vice president wanted a military strike in the face of “low confidence” intelligence that the reactor was part of a nuclear weapons program. Cheney said he wanted the United States to commit an act of war to send a message, demonstrate seriousness and enhance credibility — a frightening prospect given the doubts.

Two participants in the key National Security Council meeting in June 2007 said that after Cheney, the “lone voice,” made his arguments, Bush rolled his eyes.
