(V): Yes, but you concluded with "radiation signiture" as though that was the only relevant tool.

You also said "I'm talking about actual intelligence, not the 'WMD' fiasco type".

You mean the "intelligence" that concluded because something wasn't there it was never there? There was plenty of evidence that those weapons had been there, and been there recently. That fact was conveniently ignored. The only mistake Bush made was to telegraph our intentions of taking looking around well in advance. Plenty of time for moving those weapons elsewhere. We actually caught up to a ship containing those weapons. It was reported but apparently underplayed, because no one seemed to think it was important. Maybe it's because by that time it was old news, and the main stream press felt the public was ready for the next new and exciting news story...
