I think about ten fuel air bombs with James Foley written on the side and dropped in the vicinity of Isis headquarters ought to do the trick.
Which is precisely why Obama won't do it.
“”dropped in the vicinity of Isis headquarters””
Do they have a headquarters? I doubt if they even have homes - tents maybe. Just drop bombs on anything moving in the vast desert of Iraq...If that doesn’t do the trick, move on to Mecca.... Get their attention and be ready to take them on here. Lice!
