Senator Barack Obama said something at the presidential debate last week that almost perfectly encapsulates the difference between his foreign policy and his opponent’s: “Secretary of Defense Robert Gates himself acknowledges the war on terrorism started in Afghanistan and it needs to end there.” I don’t know if Obama paraphrased Gates correctly, but if so, they’re both wrong.

If Afghanistan were miraculously transformed into the Switzerland of Central Asia, every last one of the Middle East’s rogues gallery of terrorist groups would still exist. The ideology that spawned them would endure. Their grievances, such as they are, would not be salved. The political culture that produced them, and continues to produce more just like them, would hardly be scathed. Al Qaedism is the most radical wing of an extreme movement which was born in the Middle East and exists now in many parts of the world. Afghanistan is not the root or the source.

Al Qaeda’s politics are a product of the Arab world, specifically of the radical and totalitarian Wahhabi sect of Islam founded in the 18th Century in Saudi Arabia by the fanatical Muhammad ibn Abd-al-Wahhab. He thought the medieval interpretations of Islam even on the backward Arabian peninsula were too liberal and lenient. His most extreme followers cannot even peacefully coexist with mainstream Sunni Muslims, let alone Shia Muslims, Jews, Christians, Hindus, Buddhists, secularists, feminists, gays, or anyone else. Their global jihad is a war against the entire human race in all its diversity and plurality.
