Re: Me personally? No...
If they have that evidence, they'd be wise to disclose it before going to war. Anything discovered during or afterward will be tainted by suspicion that we planted it. Working through the UN inspectors distances the US from that suspicion.
Has the US ever manufactured a pretext for war? Hell, yes, the Gulf of Tonkin springs easily to mind. We need to be honest with ourselves and acknowledge that the US doesn't have perfect credibility, and pay attention to conserving and improving what we do have.
