This, by James Woolsey in the recent Vanity Fair article about the chastened neocons, is a good start:
[Woolsey draws a] historical parallel, to the U.S. campaigns against Native Americans in the 19th century, to make another point: that the absence of Iraqi auxiliaries deprived coalition soldiers of invaluable local intelligence. “Without the trained Iraqis, it was like the Seventh Cavalry going into the heart of Apache country in Arizona in the 1870s with no scouts. No Apache scouts. I mean, hello?”
But we need much more where this came from. The lack of this is, I think, what has caused so much ill-will towards us among Iraqis. Only when they hear the United States constantly comparing them to Native Americans will they understand how truly glorious the future we have planned for them is.
