Sadly, the story will never change. These fanatical cells will pop up like whack a moles because they rarely receive the same injustices they committed against others of a different religion or skin tone.
When I was on tour, we had to follow Geneva Laws to a Tee, and these "Mooslims" were hiding behind civilians, beheading people, and running a muck.
To defeat the enemy one must adapt to the enemies methods. That would ultimately lead to us committing the same level of violence towards them as they have towards us. AKA you behead one of ours, we behead ten of yours.
Of course this will never happen because the media and its presence has altered the nature of war so drastically that a straight and narrow line must be walked by the military at all times of conflict.
