Kevin Drum has a nice rundown of the Bush administration's incredible shrinking claims about Iraq's alleged weapons and the lack thereof:
March 2003: Weapons of mass destruction.
June 2003: Weapons of mass destruction programs.
October 2003: Weapons of mass destruction-related programs.
January 2004: Weapons of mass destruction-related program activities.
I've mentioned this before, but this reminds me of the Cheetoh-factor, in which every additional adjective makes the noun in question less true:"Cheese" = cheese
"processed cheese" = cheese, sort of
"processed cheese food" = cheese, sort of, plus other stuff that's not cheese
"processed cheese food snack product" = the food in question is orange, but contains no actual cheese.
