Nah. I never swallowed that one.
C’mon, give me one I’m not aware of.
You know, I should start a thread about this…
Remember that Jim Carrey film The Truman Show? It was a fictional representation of a real show, called the TVAA Show, that everyone except you watches on TV every day.

You underestimate the tenacity and resourcefulness of the international press. Recall the aluminum tubes and the so-called chemical weapons trailers? Bush, Cheney and company said the aluminum tubes were for enriching uranium and the trailers were for manufacturing biological or chemical weapons. The international media discredited those statements, providing information indicating the tubes were for artillery rockets and the trailers were for manufacturing hydrogen.
That’s true. But that’s because the tubes and the trailors where really Iraq’s material. If we suppose that somebody wants to create evidence, then the guys will make sure that the material they bring over is used for WMDs only.
If we also suppose that the stuff you buy on the black market (from ex-soviet labs etc.) is not traded with invoices anyway, then it should not be hard to create convincing evidence.
As Mr. Duality points out, such an operation would be exceptionally risky. If any kind of chemical or forensic test established that the finds were not genuine, it would very definitely be a matter for resignation similar to Watergate.
Of course, this whole thread is about the same being said about the entire cassus belli in the first place. What makes it special is that it was being said by conservatives!
hmmmm,
One has to wonder if they are, at some level, considering it.
I mean, they have done stuff like that in the past.
