There were a lot of indications that it was wrong even at the time, like the inspectors’ reports. We knew about the unreliability of the dodgy dossier and how baseless Khidir Hamza was. The satellite evidence was sketchy and the rest was contradictory. Al-Qaeda was also not there and we also knew that. Let’s not rewrite history: there is no certainty in intelligence, but anyone not in the CIA’s pocket knew it was most likely wrong, a far cry from what you need to legitimately attack a country.
The intelligence networks there were weak, and if people were talking about it, they may have assumed wrongly that there was something there.
Politicians hunting for excuses to do what they already want to do though, is definitely a thing.
