Detailing the evolution of the Israeli Defence Force from its pre -world war one beginning as a private company of guards (Ha-shomer), through its War of Independence and its "finest hour" in the 1967 Six Day War, and up to the 1990s with its failure to act during the 1991 first Gulf War and first Intifada (1986-1993), "The Sword and the Olive" is a compelling portrait of Israel's army, and, as the IDF is one of Israel's central institution, of the Israeli State and of Israeli society in the 20th century.
A world renowned military historian, Martin van Creveld's book is very well written and highly informed. It covers the military, social and economic aspects of the IDF, touching on almost everything, be it the role of nuclear weapons in Middle East, gender roles in the IDF (most controversial is van Creveld's thesis postulating an inverse relationship between the role of women in the Army and its prestige p. 361), or the similarities between the IDF's strategy and that of the Whermacht.
I often lament the shortages of maps in Military history books, but van Creveld's book is more offensive then most in this regard, normally there is only one map to each campaign, and I doubt anyone but the initiated can follow van Creveld's description of Israel's wars.
I am no expert in Israeli military history, most of which I gather from reading Israeli newspapers, but I was particularly surprised of van Creveld's assertions that a main motive behind Nasser's commencement of hostilities in the Six Day War was his fear of the Israeli Nuclear program. Van Creveld emerges as a critic of Israel's policy of nuclear policies, arguing that opacity failed to prevent the Six Day war and the Yom Kippur war (pp. 220-221). As a cause for the Six-Day war, van Creveld hardly mentions the internal political consideration of the Arabs, particularly in Egypt (see Michael B. Oren's brilliant "Six Days of War" for a very different perspective).
I never realized how limited the Egyptian military's moves were in the Yom Kippur war (van Creveld always refers to it as 'The October war'). In essence, Israel's maintenance of the Bar-Lev line, on the west bank of the Suez canal, was costly in terms of human life and military material, and made little or no strategic sense. By fighting on the line, Israel subjugated itself to heavy anti-aircraft and anti-tank fire, and thus did not enjoy the superiority it had in mobile warfare as in the Six Days war and the 1956 war. Israel utterly failed to take advantage of the strategic qualities of the Sinai desert as a barrier against attack on itself.
The subtitle of "The Sword and the Olive" is "A Critical History", and critical it is. Van Creveld does not spare criticism of the early pre State Israeli forces and personnel, as well as of Israel's army in the first twenty-five years of its existence, blaming Israelis for inciting Syrian fire on its tractors and questioning performances in the Six Day War.
After the 1973 war, though, van Creveld's criticisms become truly devastating. As heads of state, Golda Meir "frankly admit[ed] she did not know exactly what a division was", and Menachem Begin "kept meddling [with army affairs] even though his military knowledge had been acquired during his kindergarten years and barely developed thereafter" (p. 108). Nor is van Creveld kinder to generals: Moshe Dayan "failed to carry his point of view in the Cabinet" and "as usual" "found a way to shift responsibility [for the Bar Lev line] to others" (pp. 211-213). General 'Motta' Gur's "greatest intellectual achievement[s]" were "a series of children's books about Azzit, a heroic shepherd she-dog" (p. 249). The general intellectual poverty of the Israeli high command was manifested in Rafael Eytan "for whom wider cultural horizons simply do not exist" (p. 263).
About the current state of the Israeli army van Creveld doesn't mince words. The state of the Israeli moral is so devastating that the army had to suppress research about it. "In an army that once prided itself on truthfulness, lying has become institutionalized" van Creveld writes (p. 350). Great public outcry about accidents led to a pre-approbation of exercises and to a sharp decrease in the quantity and quality of training (p.349). Indeed, the IDF has become "soft, bloated, frequently undisciplined and undertrained", and although every successive IDF chief of staff has promised to make the army "lean and mean" again, none delivered the promise (p. 318).
Van Creveld has little doubt as to the cause of the malaise: The Occupation and the war against the Palestinians. "War... is an imitative activity in which... the two sides will learn from each other and tend to resemble each other. Thus he who fights the weak will himself become weak, and he who by "fighting" the weak behaves like a coward will end up turning into one" (p.352).
You do not have to agree with every point of van Creveld opinionated study in order to appreciate its knowledge and learning. A Superb source about the IDF, "The Sword and the Olive" is a must read for anyone interested in Israel, the Middle East, or Military history.
