What Lawrence Wright says about the effect of domestic and international politics on groups like Al Qaeda is authoritative and should be listened to:
The best ally in the struggle against violent Islamism is moderate Islam. The unfounded attacks on the backers of Park51 and others, along with such sideshows as a pastor calling for the burning of Korans, give substance to the Al Qaeda argument that the U.S. is waging a war against Islam, rather than against the terrorists’ misshapen effigy of that religion. Those stirring the pot in this debate are casting a spell that is far more dangerous than they may imagine.
