Raider,
I think you are reading too much into that paragraph. I don't see that as indications that intel is being fabricated to form a justification, just that the intel that supports it is being considred as not changing or going to change. In other words confirm the intel as best they can but nothing different is expected to be found.
That's going to be a problem with using "minutes" from a meeting as they aren't going to capture all of the meeting but contain a synopsis. In reading the memo I got the impression there was a lot more discussion other than what was placed into the minutes.
Certainly the UN wasn't going to change their mind regarding changing the saddumb regime, big on rhetoric and short on action regarding the region.
