So you admit that we are the more giving/forgiving culture, but at the same time imply that we are just as, if not more savage then radical muslims. We are civilized, they are not. We are Rome, they are barbarians. Even Rome had to be ruthless when pushed.
If you want to elicit the benefits of imperialism (the average American citizen is not eliciting any benefit from us being over there; gas prices keep rising. Only the elite are benefiting through the awarding of contracts to rebuild the infrastructure),
then you have to accept that 'barbarians' are going to fight back and retaliate (terrorism) any way they have to, since we have all the technology.
Also, I don't believe in killing and bombing people whether they're considered barbarians or not--they're still human.
