Private: We beat England when we were the guerrillas, and we beat Hitler. We beat everybody in between. We're not gonna lose to a bunch of little Asian farmers.
Sgt: Yeah? You take a look at that farmer. He can march 100 miles on no food, through a jungle, slaughter his own people, even babies. That's a soldier.
Private: Firepower. He can't soak up our firepower. I saw a photo, one of our choppers coming back with arrows in it! How do you beat a helicopter with bows and arrows?
Sergeant: How you gonna beat an enemy brave enough to fight helicopters with arrows?
Apply that to now:
We are facing an enemy that will do ANYTHING to win. They will even strap a bomb to their children and send them into a crowded area, in the hopes that his child will kill just a few of you. Any culture that believes in their cause so strongly that not only are they willing to die, but they are willing to kill their own children to get at you, is willing to do anything to win.
You can't reason with that kind of faith. You can't negotiate. Even the normal rules of war do not apply. Normally, a war is one when one side grows weary of fighting, when one side decides that the cost they are paying is too high. That isn't going to happen here. They will not stop, because they believe that their god has ordered them to kill you.
No, the only way this modern version of the crusades ends, is for one side to eliminate the other. Not beat the other, bur eliminate them.
We have no choice. They have brought the fight to us. Fort Hood, Boston, Chattanooga, San Bernardino, and more. Now it is either kill, or be killed.
