I came across this in London Review of Books:
“It’s the Oil”:
“The costs – a few billion dollars a month plus a few dozen American fatalities (a figure which will probably diminish, and which is in any case comparable to the number of US motorcyclists killed because of repealed helmet laws) – are negligible compared to $30 trillion in oil wealth, assured American geopolitical supremacy and cheap gas for voters. In terms of realpolitik, the invasion of Iraq is not a fiasco; it is a resounding success.”
