To the Wahhabis of Saudi Arabia there were two great sources of religious heretics: the Shiites, who ruled in Iran and represented a majority population in several Arab nations, including Iraq, and worse still, the Sunni Arabs, who rejected the true path as represented by the teachings of Wahhab. The puritanical form of Islam pushed by the Wahhabis was difficult to export, however, until the oil crisis of 1973, after which the Saudi government was able to fund the printing of Wahhabi literature and training of Wahhabi missionaries. In Iraq, there was some attraction to the puritanical teachings of Wahhabism among the Bedouin of the western deserts. However, with the rise to power of Saddam Hussein, Wahhabism and those who proselytized in its name were treated as enemies of the state. Wahhabism was still practiced in the shadows of Sunni mosques throughout Iraq, but anyone caught doing so was immediately arrested and put to death.

Wahhabi concerns over the weakening of the Muslim world by those who practiced anything other than pure Islam were certified in the minds of the faithful when, in April 2003, American soldiers captured Baghdad in what many Wahhabis viewed as a repeat of the sack of the city at the hands of the Mongols in 1258. Adding insult to injury, the role of Iraq's Shiites in aiding and abetting the American conquest was seen as proof positive that the only salvation for the faithful could come at the hands of a pure form of the Islamic faith, that of Wahhabism. As the American liberation dragged on into the American occupation, and the level of violence between the Shiites and Sunnis grew, the call of jihad as promulgated by the Wahhabis gained increasing credence among the tribes of western Iraq.

The longer the Americans remain in Iraq, the more violence the Americans bring down on Iraq, and the more the Americans are seen as facilitating the persecution of the Sunnis by the Shiites, the more legitimate the call of the Wahhabi fanatics become. While American strategists may speak of the rise of al-Qaida in Iraq, this is misrecognition of what is really happening. Rather than foreigners arriving and spreading Wahhabism in Iraq, the virulent sect of Islamic fundamentalism is spreading on its own volition, assisted by the incompetence and brutality of an American occupation completely ignorant of the reality of the land and people it occupies. This is the true significance of Baghdad, and any answer not reflecting this will be graded as failing.

A pop quiz, consisting of one question in two parts. Most readers might complain that it is not realistic to expect mainstream America to possess the knowledge necessary to achieve the level of comprehension required to pass this quiz. I agree. However, since the mission of the United States in Iraq has shifted from disarming Saddam to installing democracy to creating stability, I think it only fair that the American people be asked about those elements that are most relevant to the issue, namely the Shiite and Sunni faithful and how they interact with one another.

It is sadly misguided to believe that surging an additional 20,000 U.S. troops into Baghdad and western Iraq will even come close to redressing the issues raised in this article. And if you concur that the reality of Iraq is far too complicated to be understood by the average American, yet alone cured by the dispatch of additional troops, then we have a collective responsibility to ask what the hell we are doing in that country to begin with. If this doesn't represent a clarion call for bringing our men and women home, nothing does.
