These "insurgents" have one goal. They execute whatever plan they can to achieve it. There is no doctrine of "do unto others", or "be careful to blow up only the soldiers".
Fanaticals like the young man in the video know they will probably pay the ultimate price for their actions and in most cases in their own minds they are already dead so.... THEY DON'T CARE!!!!
THEY WILL KILL AT ANY COST.
Now, Someone please tell me how do you defend yourself, or your platoon, or the Iraqui citizens against fanaticals?
My answer is ANY WAY YOU CAN. I hate killing as much as anyone. Like millions of Americans, I certainly wish it would stop.
These insurgents and fanatics are not going to stop. Ever. It's been that way for longer than you or I have been alive.
