ISIL do not recognise any god, that is just BS.
They are simply 'free riders' killing off anyone that stand in their path.
We have them planted all around the world and bs everyone with their crap.
All they do is go around and find what they have called 'caliphates'.
Now if you believe their 'intent' then take another look.
They are what your president call them, LOSERS no more no less and use FEAR to obtain a life as leeches do.
So talking will not change them, cold steel run up their backsides is all they understand.
God will eventually end their cruelty.
Live by the sword, die by the sword.
