The belief in a threat was manufactured by cherry-picking any weak scraps of intelligence that could be assembled into a believable marketing pitch for an invasion. Your average mouthbreathing intel analyst wouldn’t recommend invading a taco stand based on the shady sources and thin reporting used to justify this war.

Although I am certainly not well informed, as I could not predict this scale of military operation, I'd like to say that "consensus of international media" is not worth much at times of war. Because I feel like there is never a lot of disagreement in media during such crises. Maybe after, when the situation calmed.

It wasn't piss-poor intelligence. It was misinformation crafted specifically for the purposes of justifying invasion to USA voter.
