So...do we go after Douglas J. Feith?

I'm left to wonder after reading this Washington Post article as to who is responsible and why Feith wrote what he did considering what is now known:

The report, in a passage previously marked secret, said Feith's office had asserted in a briefing given to Cheney's chief of staff in September 2002 that the relationship between Iraq and al-Qaeda was "mature" and "symbiotic," marked by shared interests and evidenced by cooperation across 10 categories, including training, financing and logistics.

Instead, the report said, the CIA had concluded in June 2002 that there were few substantiated contacts between al-Qaeda operatives and Iraqi officials and had said that it lacked evidence of a long-term relationship like the ones Iraq had forged with other terrorist groups.

Then a later paragraph of interest:

When a senior intelligence analyst working for the government's counterterrorism task force obtained an early account of the conclusions by Feith's office -- titled "Iraq and al-Qaida: Making the Case" -- the analyst prepared a detailed rebuttal calling it of "no intelligence value" and taking issue with 15 of 26 key conclusions, the report states. The analyst's rebuttal was shared with intelligence officers on the Joint Chiefs of Staff, but evidently not with others.

I recommend reading the entire article, as it contains quite a bit of information but I'm left with wondering what is next? More importantly, how we can avoid something like this happening again...
