I really don't think it would be that easy to fake this evidence and not get caught.
If you read all the conspiracy posts on FR you would assume the opposite. According to them, all the US G does is cover up with hundreds (a US Destroyer) in on the cover up. And not one peep from anyone - in this age of cell phones, internet and hungry reporters. I do agree with you. The US would be foolish to try and fake any WMD. Every gov agreed they had them otherwise, why the inspectors? He had years to hide them.
