We kill their people it is natural for some of them to seek revenge by killing us. Frankly I do not care if I die from bullets, from terrorist bomb, in car crash,...... The only thing that scares me is finding myself paralised from neck down and not be able to do anything about my state. To sum up for some of you that are "pant shiters" his the "brave new world" I would not let it get to me if I were you.
