Book Description
".....And for the first time, author Howard Blum uncovers the role of the Egyptian double agent whose masterfully woven plot nearly succeeded in toppling Israel ...."
From Publishers Weekly
"........Howard Blum begins with a familiar question: how did Israel come to be not only caught by surprise, but so unprepared that after the first days of fighting many leaders believed the survival of the state was at risk? Part of his answer is a top-level spy, code-named "the In-Law" an Egyptian at the highest levels of government who for four years before the Yom Kippur War had provided Israel with a steady flow of valuable information. That data in turn convinced Israel's military and political establishment that war was impossible unless the Arab states were a unified coalition possessing missiles and long-range bombers."
Reviewer: Jeff Leach (see more about me) from Omaha, NE USA
"...... According to Blum, several important factors contributed to the near defeat of Israel in the Yom Kippur War. Mainly, and this factor supposedly appears in print for the first time here, the Mossad and Israeli politicians made the nearly fatal mistake of relying heavily on an Egyptian double agent when formulating their national security policies. Referred to by Blum as "The Concept," the information this agent fed Israeli intelligence gave rise to a belief that until Egypt acquired long-range missiles and bombers and the Arab states unified, Israel would be safe. This "concept" soon informed all aspects of Israeli military and political policy to the point that a secret visit to Israel by the King of Jordan about the Egyptian/Syrian war plans went ignored."
