This is a dictionary definition:
Terrorize: (verb) to create and/or maintain a state of extreme fear in (someone)
If this is the meaning of terrorism, then I think we're more the terrorists than anybody else in this situation, except maybe Saddam when his regime was in power. The terrorists in the 'war on terror' didn't do much to maintain our fear, and I wouldn't even call it extreme fear, at least not after the initial 9/11 press fiasco died down. Not next to a nation of people living in fear of occupying forces right outside their door.
