This is an important book. As America hires anthropologists into its forces, Porter reminds us culture is a concept that should be handled with care.
His is a cautionary note against the new enthusiasm for 'culture' within the Pentagon and elsewhere, by survey of past intellectual engagement by western militaries with non-Europeans they confronted. Whether the British observing the Japanese in 1904, or Athenians observing Persia at the time of Salamis, the exercise has had more to do with domestic agendas in the observing country, and flattened out dissimillitude, flux and volition amongst the society being scrutinised; the new cultural turn comes across as deterministic, simplistic and unreflective.
This is all rather ahistorical; and Porter is an historian.
Amid this effort within a military to rearm culturally, we see perhaps an author's own reflections on the failure of an initial project to remake the world through putatively benevolent American power - viewed this way, ancient enmities, irrationality, tribalism, different rules and alien logic represent the converse of the stubborn failure in the last ten years of Arabs and Afghans to have become Americans.
Scrupulous as a researcher, Porter evinces instance after instance of the Taleban reinventing their cultural codes as they go, whilst Americans (and, one supposes, Brits) on both sides of the debate compete toward headier reaches of Orientalism about the 'Wild East'. (How, he poses, can Afghans both be driven by revenge and tribe, yet bound together uniquely by a charismatic mad mullah; if tribalism is supreme how can the Taleban encompass mutually contentious tribes; if the reactionary desire to return to the premodern is absolute, how can the Taleban nimbly adjust their views on the growing of opiates, the education of women or the beards of men?) He quotes Fred Burton: this is not your father's Taleban.
But Porter sees opportunity too. He maintains his essay is friendly criticism, applauds efforts of the American military to reform itself whilst fighting a war, and senses a chance to urge a military from sweeping, mystical views of culture as scripts for action towards a pragmatic sense of rival narratives, selectively enforceable taboos and competing practises which may be manipulated and instrumentalised.
Poetry comes easily to Porter, an erudite stylist at home equally with hoplitai as Hizballa. Pearls include that Anthony Eden, Prime Minister at the time of Suez, was fluent in both Persian and Arabic and holder of an Oxford First in Oriental Studies; and the 'Iraq Culture Smart Card,' distributed to American forces and illustrating static animosities amongst tribes and sects. One hopes this seductive read will wend its way to the bedtable of Stanley McChrystal and Sir David Richards.
