Didn't they target some bank building specifically in NJ? New Jersey isn't really "densely populated" in any cetain area. It's more like a big, sprawling suburb, and it's pretty small. If the terrorists wanted to go for sheer numbers of deaths, I don't think they would do it in NJ since the people aren't cramped together like in other places. Unless they hit a mall or something like that.
Truthfully, I don't think Bush even knows where to start cuz these attacks could come from anywhere. I mean they could just start bombing us right now and Bush couldn't do anything cuz he wasn't for sure when and where it was going to happen.
