One need to ask what is the driving force that cause these people to act with such barbarism. Don't tell me Islam! For they are killing Muslims more than anyone else.
CaribJ and others , you see when communism fell , it was predicted by experts that the next war will be with Islam.
FROM then to now, ask yourselves how many Muslim countries were totally destroyed by invading countrues especially our blessed America. Afghanistan gone, Iraq gone, Syria gone, Libya gone and the list goes on. One American President touted that democracy must exist , when the people of certain Islamic countries voted for a certain party, America said no they cannot recognize those Governments.
CaribJ the issue is bigger than " tribal interpretation of the Koran", that is just a smoke screen to blind you to the fact , as to who are the forces that are responsible to ensure that the Muslim.world remain in chaos and disarray .
