If a phrase is repeated often enough does it become true, or does the truth become meaningless?

Echolalia is the meaningless repetition of words or phrases associated with forms of dementia and asphasia. In the build-up to the war in Iraq certain phrases were endlessly repeated, even by members of the opposition, to the point where these empty rhetorical phrases were confused with concrete facts. I tried to record as many instances of people repeating the phrase "weapons of mass destruction" as I could stand and represent these statements in a way that draws attention to the deadening effect of their repetition, however emphatically they are expressed.
