How will we lose the war against "radical Islam"?

Well, it won't be in a tank battle. Or in the Sunni Triangle or the caves of Bora Bora. It won't be because terrorists fly three jets into the Oval Office, Buckingham Palace and the Basilica of St Peter's on the same Tuesday morning.

The war will be lost incrementally because we are unable to reverse the ongoing radicalization of Muslim populations in South Asia, Indonesia, the Balkans, Western Europe and, yes, North America. And who's behind that radicalization? Who funds the mosques and Islamic centers that in the past 30 years have set up shop on just about every Main Street around the planet?

For the answer, let us turn to a fascinating book called "Alms for Jihad: Charity And Terrorism in the Islamic World," by J. Millard Burr, a former USAID relief coordinator, and the scholar Robert O Collins.
