IS are currently using many bestial techniques against civilians in Iraq with the intention of creating terror in these communities. Is it not time that we responded with a little terror of out own, perhaps?
I actually agree that in the case of these people we all need to fight fire with fire, they do not abide by any convention that ties our hands and have clearly demonstrated that they have 'interpreted' the Koran to their own requirements to justify their barbaric behavior.
But while we have politicians who are probably trying to keep the moral high ground, when I don't think they need to, we will never defeat these sort of people, but just wait when they get back here and start back at home again and watch the 'turn the other cheek, living in a peaceful diverse population crowd' start bleating for the governments to do something, but it is too late now and these politicians will play at being 'big on the world stage' while more of our troops will be ham strung yet again and get nowhere other than more unnecessary loss of lives for no gain.
