George Bush did nothing of the sort, but there is no lack of dishonesty in the spin of those who refuse to report honestly but would rather spread flat out lies to the willing and gullible who continue to spread them.
Maureen Dowd in her syndicated May 14, 2003 column, was the one to spin that so dishonestly, and despite the fact that Andrew Sullivan and others thoroughly discredited the lie, the blindly partisan will just keep repeating it anyway.
What Dowd said was this:
Busy chasing off Saddam, the president and vice president had told us that Al Qaeda was spent. "Al Qaeda is on the run," President Bush said last week. "That group of terrorists who attacked our country is slowly but surely being decimated... They're not a problem anymore."
What Bush actually said that you quoted accurately but interpreted as Dowd did was this:
Al Qaeda is on the run. That group of terrorists who attacked our country is slowly but surely being decimated. Right now, about half of all the top Al Qaeda operatives are either jailed or dead. In either case, they're not a problem anymore.
Obviously Bush was saying that those who had been jailed or killed were not a problem any more. He never, at any time, ever said that al Qaida is not a problem any more.
One wonders how we will ever achieve the common goal and purpose as a people to fight terrorism or for any other purpose when the politics of personal destruction are constantly placed ahead of everything else?
