Very astute indeed. Cox and Forkum need to make a comic involving soccer(football for you Europeans), and the Leftists. If anyone can do it, it is them.
That's a parody, right?
The people who "moved the goalposts" are the ones who said that there was an imminent threat from WMDs, that Iraq could attack with WMDs within an hour, that the US had proof that WMD arsenals existed, and so on.
For well over a year after the above WMD allegations were made, war opponents have generally acknowledged the possibility that some chem and/or bio weapons existed somewhere (realizing that the US provided Iraq with chemical weapons technology in the past), but disputed the magnitude of the WMD threat in Bush admin's claims, claims that the Bush admin have since acknowledged were false.
