Maybe they will kill each other. But thats no comfort at all. If you read the article carefully he isn’t interested in ‘uniting muslims’. It ultimately means he & his type will kill regardless, unless we ALL subscribe to their belief. This will come to western countries sooner than one thinks. We have already let his type breed in the west.
I'd assume that ISIS has followers in place globally. This group has been so savy about their onslaught and about media message.
It's inconceivable that they haven't been anihilated already, before they become further integrated in populated areas. They're a vicious cancer, and can't wait while countries with the power to stop them play their stupid games.
What makes me sick is US culpability. ISIS in Syria benefited from US training, weapons, and financing....and our leaders are still not helping Assad fight them.
