I’ve thought since 9/11 that if they were smart, they’d do as many simultaneous attacks as possible on smaller, second and third-tier cities. Hitting NYC and DC is one thing, and certainly bad enough, but it’s very far removed from most of America. Hitting places like Cleveland, Buffalo, Baltimore, Des Moines, Milwaukee, Portland, etc. would be, I think exceedingly frightening in a way that hitting NY, DC and LA might not be.
They might opt to hit Middle America - places like Omaha, Wichita, Cincinnati, Denver.
