Al-Qaeda has succeeded in several of its main goals. It had been trying to convince Muslims that the United States wanted to invade Muslim lands, humiliate Muslim men, and rape Muslim women. Most Muslims found this charge hard to accept. The Bush administration's Iraq invasion, along with the Abu Ghuraib prison torture scandal, was perceived by many Muslims to validate Bin Laden's wisdom and foresightedness.
After the Iraq War, Bin Laden is more popular than George W. Bush even in a significantly secular Muslim country such as Turkey. This is a bizarre finding, a weird turn of events. Turks didn't start out with such an attitude. It grew up in reaction against US policies.
