"......Bolger explains that the traditional Arabic method of waging war – as described by such luminaries as T.E. Lawrence – involves raids and ambushes....." Er, yeah, in the First World War. Saddam's forces lost for exactly the same reasons the Arabs lost every war against the Israelis - the Arabs relied on outdated Soviet strategy and tactics that were meant for large-scale operations, and were consistently surprised and too slow to react due to more flexible tactics and strategies used by the Coallition (and the Israelis). The only people using the 'traditional Arab' strategies of raiding and hostage taking (an Arab tradition) are the Taleban and IS, and even they are tempering their battle tactics with those copied from the Coallition forces.
".....Bolger is ridiculously polite to his bungling political masters.... “The military offered advice hardly worth hearing”....." Like the surge, asked for by the generals on the ground, bitterly resisted by the politicians (especially by the Democrats for little other reason than "Predient Bush asked for it"), eventually agreed to and which worked? http://en.m.wikipedia.org/wiki/Iraq_War_troop_surge_of_2007
"......There was also a problem with the status of prisoners, who were not accorded the normal rights of prisoners of war. Bolger believes in a rare criticism of the politicos: “Leaving the detention situation so loosely defined would come back to bite them.".....The disasters of de-Ba'athification and the Abu Ghraib prisoner scandal....." So all political problems, resulting from political decisions, not those of the military.
".....unlike the locals, “the Americans lacked faith and staying power”....." Which has been the 'insurgent' mantra since first used by the Vietnamese (actually stated as such by Vo Nguyen Giap) against the US - that they cannot win a straight fight with a Western power and hence resort to a long-term grind in the hope the Western politicians will cave. Ironicly, Vo Nguyen Giap got the military training he needed from the American "Deer Team" during WW2 when he fought with the Allies against the Japanese. The lack of 'staying power' he predicted was as a political problem, not a military one.
TBH, it looks like Bolger was angling for a job with the politicians, he just timed his book release too late for Chuck Hagel's job. The next time the Sec of Defence slot is open he'll probably have to deal with Republicans, not Democrats, and I expect the latter might not be as willing to accept his whitewash.
