One of the one things I loved about geography in school was precisely seeing all those world flags in each unit of the textbook (usually broken up by continents), and then memorizing them. One flag is above them all, ours, but a lot of those flags were cool. Heaven help us if little kids can't memorize flags as part of school study. I guess we ought to just unplug ourselves from the rest of the world completely, too. (no outside telephone, no world travel, no foreign language study, not foreign students, no world maps. then, maybe we would be safe as a country, if we could only dig our bomb shelters a little bit deeper)
Well, if we were to do that, which we can't, the Islamo-facists like Bin Laden would love it. The one thing that makes the world a better place to live in, is having people from all cultures come into contact to learn about each other, share what each has to offer that is good, and find out what binds us together as a species. I hope we don't wind up isolated from the rest of the world.
