We wouldn't have ISIS if Saudi Arabia hadn't lost control of Al Queda over a disagreement over why the targets should be chosen by America, rather than be America.
And we wouldn't have that if it wasn't for Iran having a leadership Saudi Arabia don't like.
And we wouldn't allow that unless they also had a leadership we didn't like.
We they wouldn't have if we hadn't deposed the leader before last and imposed our own mad dictator
And we wouldn't have that popular leader if we hadn't run the country as our personal oil field
.....
And we wouldn't have that if Ug the caveman hadn't worshipped the moon in the wrong way according to Blurg the caveman.......
