This is how I explain the WMD discussion to liberals, every one of them convinced he never had any.
I blow someone away with a chrome .357 revolver and it is covered in media around the world. I use this weapon with proficiency because it is well documented, again all over the world, that I used this weapon in Iran previously.
Then Uncle Sam kicks my homie’s asses after they raid their neighbors house (Kuwait). Part of my groveling to save my hide is I promise to show that I have destroyed my chrome .357. I don’t and obfuscate for a dozen years, then Uncle Sam writes me letters saying he will search my 170,000 sq mile home. 6 months later they start a search.
Does the fact that they did not find my .357 chrome revolver prove conclusively that I never owned it? Or that I never used it?
And just before the search starts, you are seen shipping boxes to your Syrian neighbor.
