What math are you looking at where 1500 < 10?
Yes some ignorant bigots are able to delude themselves into seeing the entire history of the world as just one Muslim crime.
But some of us are not so simple minded. We have eyes and brains.
We know what Iraq was before the US terrorist attack and brutal decade long occupation and we know this sectarian violence that the US act of terrorism unleashed didn't exist and hadn't existed in over 200 years.
We know that the military leadership of ISIS is former Iraqi military that lost a job after the US brutal act of terrorism against the Iraqi people.
We know that the US was the major supplier of weapons to ISIS, albeit involuntarily, but the weapons would not have been there had the US not carried out it's massive act of terrorism against the Iraqi people.
