If and I mean a very big IF , the IS state did in fact carry out this atrocity , it is just one of many atrocity` s .
When are the powers that be , which includes the USA ,UK ,and there allies , going to exercise there authority , and once and for all put an end to this murderous bloodthirsty ,barbaric ,organization and wipe them out forever .
They obviously have the power , but not the will to do so ....So much for Western Democracy ,the USA as the leader of the free world , and her allies to back her up .Such as the UK , France , and Australia.
How pitiful
You have to come to the conclusion that they are happy to leave things as they are without a resolution.
All they are doing is keeping the status Quo.,.Content to let IS do what it want in their own land , just so long as they don`t try it on our territory .
