Cut me a break. Just months into GWB's presidency he was supposed to shut down ALL air travel in the US indefinitely because some analyst added "might fly planes into buildings or things" to his long list of possible ideas that terrorists might someday come up with?
I'm sure that would have gone over really great with the public, the media, Congress, and the entire world.
How about enhanced airport security? Maybe profile Arab men a bit?
To say he could have done nothing is ludicrous.
