http://www.nytimes.com/2006/05/10/opinion/10powers.htmlWhat finally humbled and gutted the C.I.A. after decades of Washington bureaucratic infighting was a loss of support where it counted most: the refusal of the Bush White House to accept responsibility for the two great "intelligence failures" that prompted Congress to reorganize our services.
The first failure laid at the feet of the agency was the inability to prevent the surprise attacks of 9/11. In fact, the C.I.A. (and others) warned the White House often during the first eight months of 2001 that an attack was coming and where it was coming from, but the Bush administration did nothing. For reasons of broad national psychology, the White House's failure to stir itself was simultaneously overlooked and forgiven by the public, while the C.I.A. (and others) got held to strict account for failing to predict the day and the hour.
The second failure was the claim — "with high confidence" — in a National Intelligence Estimate sent by the C.I.A. to Congress in October 2002 that Iraq was making vigorous progress on programs for weapons of mass destruction. But this finding was in effect dragged out of the agency by the White House and the Pentagon. Agency analysts working on the issue assumed that Saddam Hussein was up to something, but they knew their evidence was thin and ambiguous; many of their superiors knew about contrary evidence but suppressed it.
Everybody at the C.I.A. — from George Tenet, then the director, down — knew the agency could not tell United Nations weapons inspectors where to find anything over a period of months. The C.I.A. knew it didn't know what sort of weapons program Iraq really had, and absent White House pressure the analysts would have written an intelligence estimate reflecting their uncertainties. (It is worth noting that the Senate Intelligence Committee, despite a promise to do so, has been conspicuously reluctant to examine the source of the pressure for the drumbeat of alarming weapons intelligence, or how the White House made use of it.)
