Depends. Will Angelina Jolie still be trying to adopt a kid from there? If not, I'd say no one would really care.
Hadn't considered that angle, but you might be on to something.

I suppose it's possible that we would all spontaneously explode. After all, it's where 9/11 was plotted!
In all seriousness, I think we'd save a lot of money, time, and lives, while giving up very, very little in security.
