By Faith Alone

That’s what the AP is now reporting about the motives of the Boston bombers. I should caution that this doesn’t preclude some kind of interaction by Tamerlan with terrrorist elements when he visited Russia – and the evidence searches continue. But faith – especially fundamentalist, violent strains of Islam – is by itself a sufficient explanation. Many don’t understand this. But, as anyone with familiarity with strong religious faith will tell you, there are few things more powerful.
