Emphasis Added

From today's Washington Post:

Much of the focus on prewar expectations vs. postwar reality has been on the failure to find weapons of mass destruction. But while that was the central justification for the war in Iraq, the administration also made a wide range of claims about the ease of the invasion and the benefits that would result. Though comparisons between expectations and results are complex, it appears that the administration, based on limited human intelligence and conversations with a small corps of Iraqi exiles, was overly optimistic.

Kind of sums it all up, doesn't it?
