There's a brilliant bit of triangulation in the works, but most Americans can't see it. Ignorance of Islam and a mindless MSM, I suspect.
Islam is unified in core theology, but fractured organizationally into the two major divisions Sunni and Shiite, much the same as Protestant and Catholic in Christendom. Sharia law (Islamic legal system) has evolved slowly largely in response to Islam's decline in the face of Western civilization's gains. In general, the more "westernized" the application of Sharia law, the more prosperous the people in the 20th century. The Islamic world is seriously divided into the "haves" and "have nots".
The 1700's saw the birth of a fundamentalist movement known as Wahhabism, strong in Saudia Arabia, Quatar and W.Iraq. Appart from oil, Wahhabism would likely vanish.Wahhabism does not use Sharia law, as developed by Sunni and Shia legalists, but instead relys on interpeting the words of Mohammed directly for guidance. Wahhabists view Sunnis and Shia's as heretics. Wahhabists don't watch TV or listen to the radio - very isolated from ideas. Osama is a Wahhabist. Kind of like the Amish but without a penchant for slitting throats.
So we have two groups with bad blood who make up 99% of those involved. Then we have a 3rd group convinced the other two groups are going to hell, propped up by oil, that has provided the religious justification for hyper-violent organizations like Al-Qaeda.
Along comes Bush the younger who topples the dictatorship and forms a democratically elected republic in its place. A new model for the region offering an attractive alternative. A clear distinction between the opportunity of the "haves" versus the intellectual retreat of the "have nots". Bloody brilliant I would say.
Iraqi Muslims don't have to starting eating bacon or listening to Madonna to enjoy a 21st century democracy. But at some point they must realize that fighting over the Sunni, Shia and Wahhabist issues will just leave them dead and "have nots". Bacon and Madonna will continue. And a little girl will ask "Why don't we vacation in Afganistan Daddy?".
