Seems to me IS is doing everything the west wants them to do; play the part of an implacable enemy which has to be eradicated by military force (kerrrr-ching!) and at a cost to our liberties.
I wonder who is really pulling IS’ strings? After all if they had released their hostages unharmed, and not gone on slaughtering rampages they would be in a far better position to argue that all they want to do is establish a strict but popular islamic state; examples of which already exist elsewhere in the region.
Ponder that thought for a while; and ask yourself if David Cameron would be grieving for a working class taxi driver, living in the north, most likely not a Tory supporter, in other circumstances.
