In the debate about Iraq, it has become a convention in hawkish American circles to blame the Bush administration for bad execution of a good idea (i.e. invading a large Middle Eastern nation). “Generation Kill,” a powerful new HBO miniseries, offers a reality-based counter-narrative that shows how the American military had more than enough built-in deficiencies to undermine even a well-planned conquest. Bad execution and bad idea. I wrote a review of the series for Slate.
