So, when I was in Iraq, the Army had this program where you could attend sessions to learn about Islam with local nationals who had a security clearance. It was basically Sunday School for grown-ups, but they used the Qur'an instead of the Bible. It was led by a Muslim chaplain at the height of the hearts and minds campaign. One thing that struck me was how many questions the native Muslims had (much like Christians do about scripture when they're discussing it with more knowledgable clergy), and how easily a bad person could use their illiteracy to convince them that God wanted them to become terrorists and that they would find Paradise if they became a suicide bomber. The Qur'an is very specific about not harming innocents, and that intellectual jihad is far superior to violence. But if a group with money and growing political power assures you that your family will be taken care of, you'll escape the impoverished hell on earth you're living in, and you'll find favor with God and you can't read your Holy Book to discover that this contradicts the truth...well, that's how terrorists are made.
