The sad part is this thing happens all over the world: Iraq, Iran, China, Et al.
However, Most Americans don't see our (and when I say "our" I mean the US Govt.) "enemies" as people, they see them as "savages."
Only 20% of Americans have passports, so whatever the TV tells them about these people is Gospel.
I have been to About 20 countries on 4 continents and there is one thing I am certain of: there are good people and bad people everywhere.
