If you tried using that argument in Iraq or Afghanistan or Yemen or Pakistan you would be laughed out of town.
People there see and hear drones and aircraft every day killing muslims.
Best estimate is the US has killed 30 muslims for every American that has been killed and a good number of those have been innocent civilians or collateral damage as they say.
From the perspective of people in those countries it's a crusade.
As a matter of fact, the guy that shot up these recruitment centers in TN strictly speaking can't be called a terrorist because he attacked military troops in a time of war.
********. You can call him what you want; but he's still a terrorist.
