Re: What would you do if you were Bush?
Hire many more people in the intelligence services.
Not only to infiltrate the terrorist groups but also to be able to make the difference between what's important for the security of the country and what's not, in the enormous flow of data they get all the time. Like trusting warning messages coming from abroad.
Require some kind of device in planes that would enable the pilots to give complete control of the plane to air trafic controlers, outside of the plane.
And of course, drop NMB which is obviously useless.
