That's a really good post, thank you Battuta.
Mefustae, this article makes it clear that the information was lies - but were we lied to on purpose or not? If the government was functioning properly, I imagine they'd use more than just ONE person's testimony as a reason for war...so either they asked around and other people said so, or they were incompetent, or worse, actively and knowingly acting illegally and wrongfully by lying to the people and betraying their office.
I had relatives who were in the loop regarding the intelligence at hand at the time, and after they retired they were
intensely bitter about what happened and therefore somewhat talkative. You are greatly overestimating the indications of Iraqi WMD capability before the war. CIA interviewed defectors...and questioned their reliability. CIA's people on the ground weren't able to confirm or deny, but turned up plenty of circumstantial evidence that Saddam could not afford his old WMD programs anymore. The Defense Intelligence Agency's overheads were pressed to the limit, as they always are, but overhead photography can only reveal so much; they
could be engaged in WMD research, maybe. NSA, the cryptology guys as always being the most reliable and voluminous source of intelligence in the modern age, were resoundingly negative.
But intelligence gathering via people, and even photographs, is not a game of absolutes. If you collect the opinions and reports of everyone from the field, some of them will be deliberately falsified by people who are telling you what you want to hear, some will be more innocently wrong. Photos are interpreted; and misinterpreted on occasion.
The administration, seeking a reason to invade Iraq, embraced the reports that were in the minority. They clung to the improbable, despite being warned of its likely falsehood. They ignored the NSA. Were we lied to? No, not directly. But we were most definitely mislead.
