those that could fight for a Caliphate government are in Iraq fighting or died there.
I believe Iraq has helped all the middle east.
I think that the Islamists are in Iraq to defend "their ME world" and the Islamists are in the Balkans to make inroads into "our Western world". It's not an "either/or" -- it's an "and".
Unfortunately, while we are fighting them on one front, we are holding the door for them in the other.
