The Bush administration thinks we are all a bunch of idiots, too stupid to know the difference between truth and lies. Bush & Co. seem to think that, regardless of what the facts are, they can get us to believe the opposite. If it's day, they'll convince us is night. Black, white. You know the drill. They operate under the arrogant assumption that if they say it is so, we'll accept that declaration as the incontrovertible truth, even if that "truth" is unsupported by anything other than, "Trust us."
Why shouldn't Bush and his henchmen operate under the assumption that we're too moronic to know when they're lying to our faces? So far, their assumption has been all-too-true. Iraq was involved in September 11. Iraq nearly obtained uranium from Niger. Abu Ghraib was the work of a few bad apples. They feed us dung, call it pate, and laugh as we eat it up.
Take, for instance, the Bush administration's ongoing insistence that the U.S. does not engage in torture. As recently as November 7, 2005, despite the administration's vehement and open opposition to a Senate bill that would outlaw torture, Bush nonetheless declared (straight-faced and with all the appearances of sincerity), "We do not torture." Apparently, the administration believes that the word of our "straight-shooting" President is enough for most Americans.
