Cultural historian Paul Fussell once noted that no one prior to World War I could have conceived of how many illusions it would shatter by the time it ended. No war since has affected the world so profoundly, much less the comparatively insignificant war in Iraq. But Fussell's observation has led Rod Dreher to reflect "what things I believed at the onset of the war, that I no longer do as a result of the war."
Such exercises can be instructive, particularly when, like with Dreher's short list, the reflections reach for the significant rather than political banality (i.e., trite Bush-bashing). Still, I don’t think Dreher's list goes far enough in separating the long term implications from the naively held delusions. For example, he says, "I no longer believe the Republican Party is superior in foreign policy judgment to the Democrats."
While I agree with this assessment it fails to illuminate the road ahead. Currently, the Republicans are exhibiting a level of foreign policy incompetence that is the birth-right of the Democrats. But will that always be the case or is Bush just exceptionally incompetent? A better observation would be to note that just as 9/11 proved political realism to be obsolete, Iraq has killed neo-con style idealism.
Rather than critique Dreher's attempt, I'll take up his challenge to "add your own personal list" by listing five of the illusions that the Iraq War has shattered for me:
