Oren emphasizes that war was intended by neither side, rather, as with the July Crisis starting World War I, war resulted from an escalating series of events, some of them purely accidental. For example, in November 1966 three Israeli policemen were killed when they drove over a mine presumed to have been left by Palestinian fedayeen operating from Jordan. For unclear reasons, the usually efficient U.S. Ambassador to Israel Walworth Barbour allowed several days to pass before transmitting a condolence message from Jordan's King Hussein to Israeli Prime MinisterLevi Eshkol. In the absence of a condolence message Israel retaliated, reasoning that although the Jordanian state was not behind the attack, the people of Jordan had offered shelter to the attackers — this became one of the series of episodes that led to war. Another example was the decision of the Israelis to refrain from parading armour in their 1967 Independence Day parade in Jerusalem: although this was designed to lessen tension as Jerusalem was divided by the 1949 armistice, it was actually interpreted as a sign that the Israelis were concentrating their armour for an invasion of Syria.
Why Israel Won
Arab leaders and commanders were locked in a battle with one another to prove their militancy and outdo each other in their hatred of Israel: in the case of the Ba'athist leadership of Syria, Oren argues that war was central to their ideology, while for the Egyptians bellicose rhetoric over Israel was an attempt to gain pan-Arab leadership — even though Egypt did not want a war. Inside Egypt the leadership was dangerously split, with different factions using anti-Israeli rhetoric as a way of faction fighting inside the regime. As a result, there was no effective way for the Arabs as a whole to use their numerical superiority in a multi-front war while the armed forces of the largest Arab state were caught between confusing orders and strategies. The Israelis worked hard, planning meticulously for the possibility of war with an army that drilled diligently. By contrast, one Syrian general predicted total defeat of Israel in four days "at most." President Gamal Abdel Nasser of Egypt insisted that the Israeli Air Force was incapable of attacking Egyptian Air Force bases — in fact the successful Israeli attack on Egyptian air fields was a key factor in Israel's victory. One Egyptian official described his country's leadership as believing that "the destruction of Israel was a child's game that only required the hooking up of a few telephone lines at the commander's house and the writing of victory slogans."
Reception
The book was widely praised by critics and won the Los Angeles Times Book Prize for History. It spent seven weeks on the New York Timesbestseller list. The New York Times Book Review wrote positively of Six Days of War, as did the Washington Post which calls it "not only the best book so far written on the Six Day War, it is likely to remain the best." Positive reviews have been published by the Atlantic Monthly, the New Republic, The Guardian, Newsweek International, The Economist, and by noted historian John Keegan and noted Israeli New HistorianBenny Morris. Norman Finkelstein wrote a critical review, calling Six Days of War an "apologetic narrative" in which Oren "basically reiterates the official Israeli version of the June war."
