There was more than a “group inside” questioning the evidence – most of the intelligence community created the NIE, weighed all of the evidence, and produced the balanced view discussed by John Mace. More than 95% of us (I was in the community at the time) did our jobs in an intellectually rigorous way, despite the Administration’s drumbeat which was constantly in the news and coloring opinions around and above us.
The way it worked was that the document was composed of an outline, and under each heading was a one or two-page report by the expert on that topic. The articles were passed up the chain, edited for persuasiveness and clarity, strung together into a coherent argument, and then circulated to other experts in the field for review. When the consensus was reached, the NIE was passed up the chain for approval. The community position on almost any topic is reached that way: the expert in his cubicle writes the report after seeking peer approval, the paper floats its way up, and the CIA (and possibly the expert) gets to brief the President on the topic a few days (or hours) later.
At the same time, VP Cheney had created the Office for Special Plans. I didn’t know anything about them at the time, but I sure saw their work. At the time, I couldn’t understand how a sentence beginning “We have no evidence to suggest…” would get edited to “It is likely that…” but now I’m pretty sure I’ve figured it out based on open press reporting.
These guys were a cell of maybe 20 political types who, for some reason or another, were given a seat in the morning briefings with Bush and permitted to present their opinions on the intelligence as though they had equal credibility (I assert that they did not have anything approaching equal credibility, and that’s about as nicely as I can put it). They were not intelligence professionals. Their goal was not to examine the evidence and present the conclusions that make the most sense; their goal was to search for evidence to support the conclusions they were asked for. Someone at that high-and-mighty political level lost a fight, and the OSP guys were allowed to include their opinions in the NIE right alongside the entire community’s consensus, and wherever the positions diverged, the community position was overruled, or given equal weight at best.
Imagine that the Oscars are being given out next year by a new process: the Academy will meet and name their picks, but they can’t present their list until (a drunken college fraternity / Bill O’Reilly and Sean Hannity / a group of Muslim fundamentalists / a panel of seven-year-olds) have edited the list to their liking. If the two can’t agree, then the latter group gets to pick first place, but the Academy can “footnote” the announcement with their pick. This is how the OSP helped write the NIE. This is why we are in Iraq.
