Yes, GWB and his handlers have studied the writings of Herr Goebbels quite thoroughly. They understand that if you tell a lie often enough and consistently enough, most of the people will believe it.
A good example is the WMD bullshit. From the start, the Bush regime had to know sooner or later they would be caught out in a very big lie.
Their options now:
1) Shine it on and people will forget.
2) Make up a story like "camels ate them".
3) Bring in some of your own chemicals and bury them. "Discover" them a few months later.
My guess is that #3 is the most probable course of action and pretty well explains why Bush doesn't want UN Inspectors around.
After all, what other rationale could the US offer for keeping them out?
